The Intrigue of Garden-Path Sentences

Certainly! Garden-path sentences are a unique and useful tool for linguists and psychologists studying human language processing and memory. These sentences are constructed in a way that initially leads the reader to interpret them incorrectly, often causing confusion or a momentary misunderstanding. The term “garden-path” refers to the idiom “to be led down the garden path,” meaning to be deceived or misled.

Usually, the first part of a garden-path sentence sets up an expectation that is violated by the later part, which forces the reader to go back and reinterpret the sentence structure to make sense of it. This reanalysis process is of great interest to researchers because it reveals how people construct meaning from language, how they deal with syntactic ambiguity, and how comprehension and memory interact.

The classic example given,

“The old man the boat,”

relies on the structural ambiguity of the word “man.”

Initially, “The old man” reads like a noun phrase, leading you to expect a verb to follow.

But as you read “the boat,” confusion arises because “the boat” doesn’t function as a verb.

Here’s where the garden-path effect comes into play:

To make sense of the sentence, you must realize “man” is being used as a verb, meaning to operate or staff, and “the old” functions as the subject. The corrected interpretation is that older individuals are the ones operating the boat.

Other examples of garden-path sentences might include:

  • The horse raced past the barn and fell.” At first read, you might think the sentence is complete after “barn,” making “fell” seem out of place. However, the sentence means the horse that was raced past the barn is the one that fell.
  • The complex houses married and single soldiers and their families.” Initially, “complex” might seem to be an adjective modifying “houses,” but “houses” is in fact a verb, and “the complex” refers to a housing complex.

These sentences demonstrate the cognitive work involved in parsing and understanding language. By examining how people react to and remember such sentences, researchers can gain insights into the psychological processes underlying language comprehension and memory formation

ChatGPT’s Predictive Capability

Garden-path sentences, with their inherent complexity and potential to mislead readers temporarily, have allowed researchers to observe the processes involved in human language comprehension and memory. The study at the core of this discussion aimed to push boundaries further by exploring whether an AI model, specifically ChatGPT, could predict human memory performance concerning these sentences.

The study presented participants with pairs of sentences, where the second sentence was a challenging garden-path sentence, and the first sentence provided context. This context was either fitting, meaning it was supportive and related to the garden-path sentence, making it easier to comprehend, or unfitting, where the context was not supportive and made comprehension more challenging.

ChatGPT, mirroring human cognitive processes to some extent, was used to assess the relatedness of these two sentences and to predict the memorability of the garden-path sentence.

The participants then participated in a memory task to see how well they recalled the garden-path sentences. The correlation between ChatGPT’s predictions and human performance was significant, suggesting that ChatGPT could indeed forecast how well humans would remember sentences based on the context provided.

For instance, if the first sentence was

Jane gave up on the diet,” followed by the garden-path sentence

Eating carrots sticks to your ribs,” the fitting context (“sticks” refers to adhering to a diet plan), makes it easier for both humans and

ChatGPT to make the sentence memorable. On the contrary, an unfitting context like

The weather is changing” would offer no clarity, making the garden-path sentence less memorable due to a lack of relatability.

This reveals the role of context and relatability in language processing and memory. Sentences placed in a fitting context were rated as more memorable and, indeed, better remembered in subsequent tests. This alignment between AI assessments and human memory performance underscores ChatGPT’s predictive capability and the importance of cohesive information in language retention.

Memory Performance in Fitting vs. Unfitting Contexts

In the study under discussion, the experiment involved presenting participants with two types of sentence pairs. Each pair consisted of an initial context-setting sentence (Sentence 1) and a subsequent garden-path sentence (Sentence 2), which is a type of sentence designed to lead the reader to an initial misinterpretation.

In a “fitting” context, the first sentence provided would logically lead into the garden-path sentence, aiding comprehension by setting up the correct framework for interpretation.

For example, if Sentence 1 was “The city has no parks,” and Sentence 2 was “The ducks the children feed are at the lake,” the concept of feed here would fit with the absence of city parks, and the readers can easily understand that “the children feed” is a descriptive action relating to “the ducks.”

Conversely, in an “unfitting” context, the first sentence would not provide a supportive backdrop for the garden-path sentence, making it harder to parse and potentially less memorable.

If Sentence 1 was “John is a skilled carpenter,” and Sentence 2 remained “The ducks the children feed are at the lake,” the relationship between Sentence 1 and Sentence 2 is not clear because carpentry has no apparent connection to feeding ducks or the lake.

Participants in the study were asked to first rate the relatedness of these two sentences on a scale. The study found that participants rated fitting contexts as more related than unfitting ones.

The second part of the task was a surprise memory test where only garden-path sentences were presented, and the participants were required to recall them. It was discovered that the garden-path sentences that had a preceding fitting context were better remembered than those with an unfitting context—this indicated that context plays a critical role in how we process and retain sentences.

ChatGPT, a generative AI system, predicted this outcome. The model also rated garden-path sentences as more memorable when they had a fitting context, similar to human participants, demonstrating its capability to forecast memory performance based on context.

This highlights not only the role of context in human memory but also the potential for AI to predict human cognitive processes.

Stochastic Reasoning: A Potential Cognitive Mechanism

The study in question introduces the notion of stochastic reasoning as a potential cognitive mechanism affecting memory performance. Stochastic reasoning involves a probabilistic approach to understanding the availability of familiar information, also known as retrieval cues, which are instrumental in bolstering memory recall.

The presence of related, coherent information can elevate activation within our cognitive processes, leading to an increased likelihood of recalling that information later on.

Let’s consider an example to elucidate this concept. Imagine you are provided with the following two sentences as part of the study:

“The lawyer argued the case.”
“The evidence was compelling.”

In this case, the two sentences provide a fitting context where the first sentence creates a foundation of understanding related to legal scenarios and the second sentence builds upon that context by introducing “compelling evidence,” which is a familiar concept within the realm of law.

This clear and potent relation between the two sentences forms strong retrieval cues that enhance memory performance, as your brain more easily links “compelling evidence” with “lawyer argued the case,” which aids in later recollection.

Alternatively, if the second sentence was entirely unrelated, such as “The roses in the garden are in full bloom,” the lack of a fitting context would mean weak or absent retrieval cues. As the information related to law does not connect well with the concept of blooming roses, this results in less effective memory performance due to the disjointed nature of the information being processed.

The study found that when sentences are placed within a fitting context that aligns well with our existing knowledge and background, the relationship between the sentences is clear, thus providing stronger cues that streamline the retrieval process and lead to better retention and recall of information.

This reflects the significance of stochastic reasoning and the role of familiarity and coherence in enhancing memory performance.

ChatGPT vs. Human Language Processing

The paragraph delves into the intriguing observation that ChatGPT, a language model developed by OpenAI, and humans share a commonality in how they process language despite the underlying differences in their “operating systems” or cognitive architectures 1. Both seem to rely significantly on the surrounding context to comprehend incoming information and to integrate it coherently with the preceding context.

To illustrate, consider the following example of a garden-path sentence: “The old man the boat.” This sentence is confusing at first because “man” is often used as a verb, and the reader initially interprets “the old man” as a noun phrase.

The confusion is cleared up when provided with a fitting context, such as “elderly people are in control.” Now, the phrase makes sense—’man’ is understood as a verb meaning ‘to staff,’ and the garden-path sentence is interpreted correctly to mean that elderly people are the ones operating the boat.

However, if the preceding sentence was unrelated, such as “The birds flew to the south,” there is no helpful context to parse “The old man the boat” correctly, and it remains confusing, illustrating an unfitting context. This unfitness affects the recall of the garden-path sentence in the memory task, as it lacks clear, coherent links to preexisting knowledge or context that facilitate understanding and later recall.

The study’s findings depicted that when humans assess two sentences as being more related, which is naturally higher in fitting contexts than in unfitting ones, the memory performance for the ambiguous (garden-path) sentence also improves.

In a compelling parallel, ChatGPT generated similar assessments when given the same sentences, assigning higher relatedness values to fitting contexts over unfitting ones. This correlation suggests a similarity in how ChatGPT and humans use context to parse and remember new information.

Furthermore, the relatedness ratings were not just abstract assessments but tied directly to the actual memorability of the sentences. As with humans, ChatGPT’s predictions of memorability were also higher for sentences in fitting contexts, a phenomenon that may stem from its sophisticated language processing capabilities that crudely mimic cognitive processes involved in human memory.

This similarity in the use of context and its impact on memory retention is remarkable, considering the different mechanisms through which humans and machine learning models operate.

Broader Implications and the Future

The paragraph outlines the wider ramifications of the research findings on the predictive capabilities of generative AI like ChatGPT regarding human memory performance in language tasks. The research suggests that these AI models could have practical applications in several domains, including:

Education:

AI could be used to tailor learning experiences for students with diverse cognitive needs. By understanding how different students retain information, AI applications could guide educators in adjusting teaching materials, pace, and instructional approaches to cater to individual learning styles and abilities.

For example, if a student is struggling with remembering historical dates, the AI might suggest teaching methods or materials that align with their learning patterns to improve retention.

Eldercare:

The study indicates that older adults often face a cognitive slowdown, which could lead to more frequent memory problems. AI, once trained on data taking into account individual cognitive differences, could aid in developing personalized cognitive training and therapy plans aimed at enhancing mental functions in the elderly.

For instance, a cognitive enhancement program might be customized for an older adult who has difficulty recalling names or recent events by using strategies found effective through AI analysis.

Impact of AI on human cognition

The implications here go beyond just predicting human behavior; they extend to potentially improving cognitive processes through the intervention of AI.

These potential applications represent a synergistic relationship between AI and human cognitive research, where the insights gained from one field can materially benefit the other.

Furthermore, adaptive AI systems could continually learn and improve their predictions and recommendations based on new data, thereby creating a dynamic and responsive tool for cognitive enhancement and education.

That said, let’s have a quick look at the 5 most famous AI disasters that occurred recently:

 

5 famous AI disasters

ai disasters and ai risks

AI is not inherently causing disasters in society, but there have been notable instances where the application of AI has led to negative consequences or exacerbations of pre-existing issues:

Generative AI in legal research

An attorney named Steven A. Schwartz used OpenAI’s ChatGPT for legal research, which led to the submission of at least six nonexistent cases in a lawsuit’s brief against Colombian airline Avianca.

The brief included fabricated names, docket numbers, internal citations, and quotes. The use of ChatGPT resulted in a fine of $5,000 for both Schwartz and his partner Peter LoDuca, and the dismissal of the lawsuit by US District Judge P. Kevin Castel.

Machine learning in healthcare

AI tools developed to aid hospitals in diagnosing or triaging COVID-19 patients were found to be ineffective due to training errors.

The UK’s Turing Institute reported that these predictive tools made little to no difference. Failures often stem from the use of mislabeled data or data from unknown sources.

An example includes a deep learning model for diagnosing COVID-19 that was trained on a dataset with scans of patients in different positions and was unable to accurately diagnose the virus due to these inconsistencies.

AI in real estate at Zillow

Zillow utilized a machine learning algorithm to predict home prices for its Zillow Offers program, aiming to buy and flip homes efficiently.

However, the algorithm had a median error rate of 1.9%, and, in some cases, as high as 6.9%, leading to the purchase of homes at prices that exceeded their future selling prices.

This misjudgment resulted in Zillow writing down $304 million in inventory and led to a workforce reduction of 2,000 employees, or approximately 25% of the company.

Bias in AI recruitment tools:

Amazon’s case is not detailed in the provided sources, but referencing similar issues of bias in recruitment tools, it’s notable that AI algorithms can unintentionally incorporate biases from the data they are trained on.

In AI recruiting tools, this means if the training datasets have more resumes from one demographic, such as men, the algorithm might show preference to those candidates, leading to discriminatory hiring practices.

AI in recruiting software at iTutorGroup:

iTutorGroup’s AI-powered recruiting software was programmed with criteria that led it to reject job applicants based on age. Specifically, the software discriminated against female applicants aged 55 and over, and male applicants aged 60 and over.

This resulted in over 200 qualified candidates being unfairly dismissed by the system. The US Equal Employment Opportunity Commission (EEOC) took action against iTutorGroup, which led to a legal settlement. iTutorGroup agreed to pay $365,000 to resolve the lawsuit and was required to adopt new anti-discrimination policies as part of the settlement.

 

Ethical concerns for organizations – Post-deployment of AI

The use of AI within organizations brings forth several ethical concerns that need careful attention. Here is a discussion on the rising ethical concerns post-deployment of AI:

Data Privacy and Security:

The reliance on data for AI systems to make predictions or decisions raises significant concerns about privacy and security. Issues arise regarding how data is gathered, stored, and used, with the potential for personal data to be exploited without consent.

Bias in AI:

When algorithms inherit biases present in the data they are trained on, they may make decisions that are discriminating or unjust. This can result in unfair treatment of certain demographics or individuals, as seen in recruitment, where AI could prioritize certain groups over others unconsciously.

Accessibility and Equity:

Ensuring equitable access to the benefits of AI is a major ethical concern. Marginalized communities often have lesser access to technology, which may leave them further behind. It is crucial to make AI tools accessible and beneficial to all, to avoid exacerbating existing inequalities.

Accountability and Decision-Making:

The question of who is accountable for decisions made by AI systems is complex. There needs to be transparency in AI decision-making processes and the ability to challenge and appeal AI-driven decisions, especially when they have significant consequences for human lives.

Overreliance on Technology:

There is a risk that overreliance on AI could lead to neglect of human judgment. The balance between technology-aided decision-making and human expertise needs to be maintained to ensure that AI supports, not supplants, human roles in critical decision processes.

Infrastructure and Resource Constraints:

The implementation of AI requires infrastructure and resources that may not be readily available in all regions, particularly in developing countries. This creates a technological divide and presents a challenge for the widespread and fair adoption of AI.

These ethical challenges require organizations to establish strong governance frameworks, adopt responsible AI practices, and engage in ongoing dialogue to address emerging issues as AI technology evolves.

Large language model bootcamp

 

InstructGPT architecture

Let’s break down the architecture of InstructGPT in a way that’s easy to digest. Imagine that you’re building a really complex LEGO model. Now, instead of LEGO bricks, InstructGPT uses something called a transformer architecture, which is just a fancy term for a series of steps that help the computer understand and generate human-like text.

At the heart of this architecture are things called attention mechanisms. Think of these as little helpers inside the computer’s brain that pay close attention to each word in a sentence and decide which other words it should pay attention to. This is important because, in language, the meaning of a word often depends on the other words around it.

Now, InstructGPT takes this transformer setup and tunes it with something called Reinforcement Learning from Human Feedback (RLHF). This is like giving the computer model a coach who gives it tips on how to get better at its job. For InstructGPT, the job is to follow instructions really well.

So, the “coach” (which is actually people giving feedback) helps InstructGPT understand which answers are good and which aren’t, kind of like how a teacher helps a student understand right from wrong answers. This training helps InstructGPT give responses that are more useful and on point.

And that’s the gist of it. InstructGPT is like a smart LEGO model built with special bricks (transformers and attention mechanisms) and coached by humans to be really good at following instructions and helping us out.

Large language models (LLMs) are a fascinating aspect of machine learning.

Regarding selective prediction in large language models, it refers to the model’s ability to generate specific predictions or responses based on the given input.

This means that the model can focus on certain aspects of the input text to make more relevant or context-specific predictions. For example, if asked a question, the model will selectively predict an answer relevant to that question, ignoring unrelated information.

 

They function by employing deep learning techniques and analyzing vast datasets of text. Here’s a simple breakdown of how they work:

  1. Architecture: LLMs use a transformer architecture, which is highly effective in handling sequential data like language. This architecture allows the model to consider the context of each word in a sentence, enabling more accurate predictions and the generation of text.
  2. Training: They are trained on enormous amounts of text data. During this process, the model learns patterns, structures, and nuances of human language. This training involves predicting the next word in a sentence or filling in missing words, thereby understanding language syntax and semantics.
  3. Capabilities: Once trained, LLMs can perform a variety of tasks such as translation, summarization, question answering, and content generation. They can understand and generate text in a way that is remarkably similar to human language.

 

Learn to build LLM applications

 

How selective predictions work in LLMs

Selective prediction in the context of large language models (LLMs) is a technique aimed at enhancing the reliability and accuracy of the model’s outputs. Here’s how it works in detail:

  1. Decision to Predict or Abstain: At its core, selective prediction involves the model making a choice about whether to make a prediction or to abstain from doing so. This decision is based on the model’s confidence in its ability to provide a correct or relevant answer.
  2. Improving Reliability: By allowing LLMs to abstain from making predictions in cases where they are unsure, selective prediction improves the overall reliability of the model. This is crucial in applications where providing incorrect information can have serious consequences.
  3. Self-Evaluation: Some selective prediction techniques involve self-evaluation mechanisms. These allow the model to assess its own predictions and decide whether they are likely to be accurate or not. For example, experiments with models like PaLM-2 and GPT-3 have shown that self-evaluation-based scores can improve accuracy and correlation with correct answers.
  4. Advanced Techniques like ASPIRE: Google’s ASPIRE framework is an example of an advanced approach to selective prediction. It enhances the ability of LLMs to make more confident predictions by effectively assessing when to predict and when to withhold a response.
  5. Selective Prediction in Applications: This technique can be particularly useful in applications like conformal prediction, multi-choice question answering, and filtering out low-quality predictions. It ensures that the model provides responses only when it has a high degree of confidence, thereby reducing the risk of disseminating incorrect information.

 

Large language model bootcamp

 

Here’s how it works and improves response quality:

Example:

Imagine using a language model for a task like answering trivia questions. The LLM is prompted with a question: “What is the capital of France?” Normally, the model would generate a response based on its training.

However, with selective prediction, the model first evaluates its confidence in its knowledge about the answer. If it’s highly confident (knowing that Paris is the capital), it proceeds with the response. If not, it may abstain from answering or express uncertainty rather than providing a potentially incorrect answer.

 

 

Improvement in response quality:

  1. Reduces Misinformation: By abstaining from answering when uncertain, selective prediction minimizes the risk of spreading incorrect information.
  2. Enhances Reliability: It improves the overall reliability of the model by ensuring that responses are given only when the model has high confidence in their accuracy.
  3. Better User Trust: Users can trust the model more, knowing that it avoids guessing when unsure, leading to higher quality and more dependable interactions.

Selective prediction, therefore, plays a vital role in enhancing the quality and reliability of responses in real-world applications of LLMs.

 

ASPIRE framework for selective predictions

The ASPIRE framework, particularly in the context of selective prediction for Large Language Models (LLMs), is a sophisticated process designed to enhance the model’s prediction capabilities. It comprises three main stages:

  1. Task-Specific Tuning: In this initial stage, the LLM is fine-tuned for specific tasks. This means adjusting the model’s parameters and training it on data relevant to the tasks it will perform. This step ensures that the model is well-prepared and specialized for the type of predictions it will make.
  2. Answer Sampling: After tuning, the LLM engages in answer sampling. Here, the model generates multiple potential answers or responses to a given input. This process allows the model to explore a range of possible predictions rather than settle on the first plausible option.
  3. Self-Evaluation Learning: The final stage involves self-evaluation learning. The model evaluates the generated answers from the previous stage, assessing their quality and relevance. It learns to identify which answers are most likely to be correct or useful based on its training and the specific context of the question or task.

Helping businesses with informed decision-making

Businesses and industries can greatly benefit from adopting selective prediction frameworks like ASPIRE in several ways:

  1. Enhanced Decision Making: By using selective prediction, businesses can make more informed decisions. The framework’s focus on task-specific tuning and self-evaluation allows for more accurate predictions, which is crucial in strategic planning and market analysis.
  2. Risk Management: Selective prediction helps in identifying and mitigating risks. By accurately predicting market trends and customer behavior, businesses can proactively address potential challenges.
  3. Efficiency in Operations: In industries such as manufacturing, selective prediction can optimize supply chain management and production processes. This leads to reduced waste and increased efficiency.
  4. Improved Customer Experience: In service-oriented sectors, predictive frameworks can enhance customer experience by personalizing services and anticipating customer needs more accurately.
  5. Innovation and Competitiveness: Selective prediction aids in fostering innovation by identifying new market opportunities and trends. This helps businesses stay competitive in their respective industries.
  6. Cost Reduction: By making more accurate predictions, businesses can reduce costs associated with trial and error and inefficient processes.

EDiscovery plays a vital role in legal proceedings. It is the process of identifying, collecting, and producing electronically stored information (ESI) in response to a request for production in a lawsuit or investigation.

Anyhow, with the exponential growth of digital data, manual document review can be a challenging task. Hence, AI has the potential to revolutionize the eDiscovery process, particularly in document review, by automating tasks, increasing efficiency, and reducing costs.

The Role of AI in eDiscovery

AI is a broad term that encompasses various technologies, including machine learning, natural language processing, and cognitive computing. In the context of eDiscovery, it is primarily used to automate the document review process, which is often the most time-consuming and costly part of eDiscovery.

AI-powered document review tools can analyze vast amounts of data quickly and accurately, identify relevant documents, and even predict document relevance based on previous decisions. This not only speeds up the review process but also reduces the risk of human error.

The Role of Machine Learning

Machine learning, which is a component of AI, involves computer algorithms that improve automatically through experience and the use of data. In eDiscovery, machine learning can be used to train a model to identify relevant documents based on examples provided by human reviewers.

The model can review and categorize new documents automatically. This process, known as predictive coding or technology-assisted review (TAR), can significantly reduce the time and cost of document review.

Natural Language Processing and Its Significance

Natural Language Processing (NLP) is another AI technology that plays an important role in document review. NLP enables computers to understand, interpret, and generate human language, including speech.

Benefits of AI in Document Review

Efficiency

AI can significantly speed up the document review process. AI can analyze thousands of documents in a matter of minutes, unlike human reviewers, who can only review a limited number of documents per day. This can significantly reduce the time required for document review.

Moreover, AI can work 24/7 without breaks, further increasing efficiency. This is particularly beneficial in time-sensitive cases where a quick review of documents is essential.

Accuracy

AI can also improve the accuracy of document reviews. Human reviewers often make mistakes, especially when dealing with large volumes of data. However, AI algorithms can analyze data objectively and consistently, reducing the risk of errors.

Furthermore, AI can learn from its mistakes and improve over time. This means that the accuracy of document review can improve with each case, leading to more reliable results.

Cost-effectiveness

By automating the document review process, AI can significantly reduce the costs associated with eDiscovery. Manual document review requires a team of reviewers, which can be expensive. However, AI can do the same job at a fraction of the cost.

Moreover, by reducing the time required for document review, AI can also reduce the costs associated with legal proceedings. This can make legal services more accessible to clients with limited budgets.

Challenges and Considerations

While AI offers numerous benefits, it also presents certain challenges. These include issues related to data privacy, the accuracy of AI algorithms, and the need for human oversight.

Data privacy

AI algorithms require access to data to function effectively. However, this raises concerns about data privacy. It is essential to ensure that AI tools comply with data protection regulations and that sensitive information is handled appropriately.

Accuracy of AI algorithms

While AI can improve the accuracy of document review, it is not infallible. Errors can occur, especially if the AI model is not trained properly. Therefore, it is crucial to validate the accuracy of AI tools and to maintain human oversight to catch any errors.

Human oversight

Despite the power of AI, human oversight is still necessary. AI can assist in the document review process, but it cannot replace human judgment. Lawyers still need to review the results produced by AI tools and make final decisions.

Moreover, navigating AI’s advantages involves addressing associated challenges. Data privacy concerns arise from AI’s reliance on data, necessitating adherence to privacy regulations to protect sensitive information. Ensuring the accuracy of AI algorithms is crucial, demanding proper training and human oversight to detect and rectify errors. Despite AI’s prowess, human judgment remains pivotal, necessitating lawyer oversight to validate AI-generated outcomes.

Conclusion

AI has the potential to revolutionize the document review process in eDiscovery. It can automate tasks, reduce costs, increase efficiency, and improve accuracy. Yet, challenges exist. To unlock the full potential of AI in document review, it is essential to address these challenges and ensure that AI tools are used responsibly and effectively.
