Large language model bootcamp

 

Priority Access to GPT-4: Enhancing Performance

Advanced-Data Analysis was previously exclusive to ChatGPT Plus subscribers, the premium $20-per-month tier for the consumer ChatGPT web and mobile applications. OpenAI intends for ChatGPT Plus to coexist with ChatGPT Enterprise, emphasizing their complementary nature.

ChatGPT Enterprise operates on GPT-4, OpenAI’s flagship AI model, just like ChatGPT Plus. However, ChatGPT Enterprise customers receive priority access to GPT-4, resulting in performance that is twice as fast as the standard GPT-4 and offering an extended context window of approximately 32,000 tokens (around 25,000 words).

Data Security: A Paramount Concern Addressed

The context window denotes the text the model considers before generating additional text, while tokens represent individual units of text (e.g., the word “fantastic” might be split into the tokens “fan,” “tas,” and “tic”). Larger context windows in models reduce the likelihood of “forgetting” recent conversation content.

OpenAI is actively addressing business concerns by affirming that it will not use business data sent to ChatGPT Enterprise or any usage data for model training. Additionally, all interactions with ChatGPT Enterprise are encrypted during transmission and while stored.

OpenAI’s Announcement on LinkedIn of ChatGPT Enterprise

 

ChatGPT’s Impact on Businesses

OpenAI asserts strong interest from businesses in a business-focused ChatGPT, noting that ChatGPT, one of the fastest-growing consumer applications in history, has been embraced by teams in over 80% of Fortune 500 companies.

Monetizing the Innovation: Financial Considerations

However, the sustainability of ChatGPT remains uncertain. According to Similarweb, global ChatGPT traffic decreased by 9.7% from May to June, with an 8.5% reduction in average time spent on the web application. Possible explanations include the launch of OpenAI’s ChatGPT app for iOS and Android and the summer vacation period, during which fewer students use ChatGPT for academic assistance. Increased competition may also be contributing to this decline.

OpenAI faces pressure to monetize the tool, considering the company’s reported expenditure of over $540 million in the previous year on ChatGPT development and talent acquisition from companies like Google, as mentioned in The Information. Some estimates suggest that ChatGPT costs OpenAI $700,000 daily to operate.

Nonetheless, in fiscal year 2022, OpenAI generated only $30 million in revenue. CEO Sam Altman has reportedly set ambitious goals, aiming to increase this figure to $200 million this year and $1 billion in the next, with ChatGPT Enterprise likely playing a crucial role in these plans.

This approach focused on individualization strives to render ChatGPT Enterprise flexible to a range of corporate prerequisites, delivering a more personalized encounter compared to its standardized predecessors.

Is ChatGPT Enterprise Pricing Justified?

ChatGPT Enterprise operates on the GPT-4 model, OpenAI’s most advanced AI model to date, a feature shared with the more affordable ChatGPT Plus. However, there are notable advantages for Enterprise subscribers. These include privileged access to an enhanced GPT-4 version that functions at double the speed and provides a more extensive context window, encompassing approximately 32,000 tokens, equivalent to around 25,000 words.

Understanding the significance of the context window is essential. Put simply, it represents the amount of text the model can consider before generating new content. Tokens are the discrete text components the model processes; envision breaking down the word “fantastic” into segments like “fan,” “tas,” and “tic.” A model with an extensive context window is less prone to losing track of the conversation, leading to a smoother and more coherent user experience.

Regarding concerns about data privacy, a significant issue for businesses that have previously restricted employee access to consumer-oriented ChatGPT versions, OpenAI assures that ChatGPT Enterprise models will not be trained using any business-specific or user-specific data. Furthermore, the company has implemented encryption for all conversations, ensuring data security during transmission and storage.

Taken together, these enhancements suggest that ChatGPT Enterprise could offer substantial value, particularly for organizations seeking high-speed, secure, and sophisticated language model applications.

Understanding the concept of Docker and Containers

The concept of Docker for Data Science is to help developers develop and ship their code easily, in the form of containers. These containers can be deployed anywhere, making the process of setting up a project much simpler, ensuring consistency and reproducibility across different environments. 

The structure of a Docker Image is that it contains instructions for creating a container. It is a snapshot of a filesystem with application code and all its dependencies. Docker Container, however, is a runnable instance of a Docker Image. You can play around with both using CLI, or GUI using Docker Desktop 

The underlying principle used to create isolated environments for running applications is called Virtualization. You may already have an idea of virtual machines which use the same concept. Both Docker and VMs aim to achieve isolation, but they use different approaches to accomplish this.  

VMs provide stronger isolation by running complete operating systems, while Docker containers leverage the host OS’s kernel, making them more lightweight and efficient in terms of resource usage. Docker containers are well-suited for deploying applications consistently across various environments, while VMs are better for running different operating systems on the same physical hardware.

Docker for data science: A tutorial 

Prerequisites: 

  1. Install Docker Desktop for Windows: Download and install Docker Desktop for Windows from the official website.
  2. Install Visual Studio Code: Download and install Visual Studio Code from the official website: https://code.visualstudio.com/ 

Step 1: Set Up Your Project Directory 

Create a project directory for your data science project. Inside the project directory, create a Python script (e.g., code_1.py) that contains your data science code. 

Let us suppose you have a file named code_1.py which contains:

This is just a simple example to demonstrate data analysis and machine learning operations

Step 2: Dockerfile 

Create a file in the project directory. The file contains instructions to build the image for your data science application.  

Step 3: Build the Docker Image 

Open a terminal or command prompt and navigate to your project directory. Build the image using the following command: 

Note: Remember to not skip the “.” as it serves as a positional argument.

Step 4: Run the Docker Container 

Once the image is built, you can run the Docker container with the following command: 

This will execute the Python script inside the container, and you will see the output in the terminal. 

Step 5: VS Code Integration 

To run and debug your data science code inside the container directly from VS Code, follow these steps:  

  • Install the “Remote – Containers” extension in VS Code. This extension allows you to work with development containers directly from VS Code. 
  • Open your project directory in VS Code. 
  • Click on the green icon at the bottom-left corner of the VS Code window. It should say “Open a Remote Window.” Select “Remote-Containers: Reopen in Container” from the menu that appears. 
  • VS Code will now reopen inside the Docker container. You will have access to all the tools and dependencies installed in the container. 
  • Open your code_1.py script in VS Code and start working on your data science code as usual. 
  • When you are ready to run the Python script, simply open a terminal in VS Code and execute it using the command: 

You can also use the VS Code debugger to set breakpoints, inspect variables, and debug your data science code inside the container. With this setup, you can develop and run your data science code using Docker and VS Code locally. 

Next, let us move toward the Docker Hub and Docker Container Registry, which will show us its power. By setting up a Docker container registry, publishing your Docker images, and pulling them from Docker Hub, you can easily share your data science projects with others or deploy them on different machines while ensuring consistency across environments. Docker Hub serves as a central repository for Docker images, making it convenient to manage and distribute your containers. 

Step 6: Set Up Docker Container Registry (Docker Hub): 

  1. Create an account on Docker Hub (https://hub.docker.com/). 
  2. Login to Docker Hub using the following command in your terminal or command prompt: 

Step 7: Tag and push the Docker Image to Docker Hub: 

After building the image, tag it with your  Hub username and the desired repository name. The repository name can be anything you choose. It is good practice to include a version number as well.  

Step 8: Pull and Run the Docker Image from Docker Hub: 

Now, let us demonstrate how to pull the Docker image from Docker Hub on a different machine or another environment: 

  1. On the new machine, install it and ensure it is running. 
  2. Pull the Docker image from Docker Hub using the following command: 

This will execute the same script we initially had inside the container, and you should see the same output as before.

Researchers, statisticians, and data analysts rely on histograms to gain insights into data distributions, identify patterns, and detect outliers. Data scientists and machine learning practitioners use histograms as part of exploratory data analysis and feature engineering. Overall, anyone working with numerical data and seeking to gain a deeper understanding of data distributions can benefit from information on histograms.

Defining histograms

A histogram is a type of graphical representation of data that shows the distribution of numerical values. It consists of a set of vertical bars, where each bar represents a range of values, and the height of the bar indicates the frequency or count of data points falling within that range.   

Histograms
Histograms

Histograms are commonly used in statistics and data analysis to visualize the shape of a data set and to identify patterns, such as the presence of outliers or skewness. They are also useful for comparing the distribution of different data sets or for identifying trends over time. 

The picture above shows how 1000 random data points from a normal distribution with a mean of 0 and standard deviation of 1 are plotted in a histogram with 30 bins and black edges.  

Advantages of histograms

  • Visual Representation: Histograms provide a visual representation of the distribution of data, enabling us to observe patterns, trends, and anomalies that may not be apparent in raw data.
  • Easy Interpretation: Histograms are easy to interpret, even for non-experts, as they utilize a simple bar chart format that displays the frequency or proportion of data points in each bin.
  • Outlier Identification: Histograms are useful for identifying outliers or extreme values, as they appear as individual bars that significantly deviate from the rest of the bars.
  • Comparison of Data Sets: Histograms facilitate the comparison of distribution between different data sets, enabling us to identify similarities or differences in their patterns.
  • Data Summarization: Histograms are effective for summarizing large amounts of data by condensing the information into a few key features, such as the shape, center, and spread of the distribution.

Creating a histogram using Matplotlib library

We can create histograms using Matplotlib by following a series of steps. Following the import statements of the libraries, the code generates a set of 1000 random data points from a normal distribution with a mean of 0 and standard deviation of 1, using the `numpy.random.normal()` function. 

  1. The plt.hist() function in Python is a powerful tool for creating histograms. By providing the data, number of bins, bar color, and edge color as input, this function generates a histogram plot.
  2. To enhance the visualization, the xlabel(), ylabel(), and title() functions are utilized to add labels to the x and y axes, as well as a title to the plot.
  3. Finally, the show() function is employed to display the histogram on the screen, allowing for detailed analysis and interpretation.

Overall, this code generates a histogram plot of a set of random data points from a normal distribution, with 30 bins, blue bars, black edges, labeled axes, and a title. The histogram shows the frequency distribution of the data, with a bell-shaped curve indicating the normal distribution.  

Customizations available in Matplotlib for histograms  

In Matplotlib, there are several customizations available for histograms. These include:

  1. Adjusting the number of bins.
  2. Changing the color of the bars.
  3. Changing the opacity of the bars.
  4. Changing the edge color of the bars.
  5. Adding a grid to the plot.
  6. Adding labels and a title to the plot.
  7. Adding a cumulative density function (CDF) line.
  8. Changing the range of the x-axis.
  9. Adding a rug plot.

Now, let’s see all the customizations being implemented in a single example code snippet: 

In this example, the histogram is customized in the following ways: 

  • The number of bins is set to `20` using the `bins` parameter.
  • The transparency of the bars is set to `0.5` using the `alpha` parameter.
  • The edge color of the bars is set to `black` using the `edgecolor` parameter.
  • The color of the bars is set to `green` using the `color` parameter.
  • The range of the x-axis is set to `(-3, 3)` using the `range` parameter.
  • The y-axis is normalized to show density using the `density` parameter.
  • Labels and a title are added to the plot using the `xlabel()`, `ylabel()`, and `title()` functions.
  • A grid is added to the plot using the `grid` function.
  • A cumulative density function (CDF) line is added to the plot using the `cumulative` parameter and `histtype=’step’`.
  • A rug plot showing individual data points is added to the plot using the `plot` function.

Creating a histogram using ‘Seaborn’ library: 

We can create histograms using Seaborn by following the steps: 

  • First and foremost, importing the libraries: `NumPy`, `Seaborn`, `Matplotlib`, and `Pandas`. After importing the libraries, a toy dataset is created using `pd.DataFrame()` of 1000 samples that are drawn from a normal distribution with mean 0 and standard deviation 1 using NumPy’s `random.normal()` function. 
  • We use Seaborn’s `histplot()` function to plot a histogram of the ‘data’ column of the DataFrame with `20` bins and a `blue` color. 
  • The plot is customized by adding labels, and a title, and changing the style to a white grid using the `set_style()` function. 
  • Finally, we display the plot using the `show()` function from matplotlib. 

  

Overall, this code snippet demonstrates how to use Seaborn to plot a histogram of a dataset and customize the appearance of the plot quickly and easily. 

Customizations available in Seaborn for histograms

Following is a list of the customizations available for Histograms in Seaborn: 

  1. Change the number of bins.
  2. Change the color of the bars.
  3. Change the color of the edges of the bars.
  4. Overlay a density plot on the histogram.
  5. Change the bandwidth of the density plot.
  6. Change the type of histogram to cumulative.
  7. Change the orientation of the histogram to horizontal.
  8. Change the scale of the y-axis to logarithmic.

Now, let’s see all these customizations being implemented here as well, in a single example code snippet: 

In this example, we have done the following customizations:

  1. Set the number of bins to `20`.
  2. Set the color of the bars to `green`.
  3. Set the `edgecolor` of the bars to `black`.
  4. Added a density plot overlaid on top of the histogram using the `kde` parameter set to `True`.
  5. Set the bandwidth of the density plot to `0.5` using the `kde_kws` parameter.
  6. Set the histogram to be cumulative using the `cumulative` parameter.
  7. Set the y-axis scale to logarithmic using the `log_scale` parameter.
  8. Set the title of the plot to ‘Customized Histogram’.
  9. Set the x-axis label to ‘Values’.
  10. Set the y-axis label to ‘Frequency’.

Limitations of Histograms: 

Histograms are widely used for visualizing the distribution of data, but they also have limitations that should be considered when interpreting them. These limitations are jotted down below: 

  1. They can be sensitive to the choice of bin size or the number of bins, which can affect the interpretation of the distribution. Choosing too few bins can result in a loss of information while choosing too many bins can create artificial patterns and noise.
  2. They can be influenced by outliers, which can skew the distribution or make it difficult to see patterns in the data.
  3. They are typically univariate and cannot capture relationships between multiple variables or dimensions of data.
  4. Histograms assume that the data is continuous and does not work well with categorical data or data with large gaps between values.
  5. They can be affected by the choice of starting and ending points, which can affect the interpretation of the distribution.
  6. They do not provide information on the shape of the distribution beyond the binning intervals.

 It’s important to consider these limitations when using histograms and to use them in conjunction with other visualization techniques to gain a more complete understanding of the data. 

 Wrapping up

In conclusion, histograms are powerful tools for visualizing the distribution of data. They provide valuable insights into the shape, patterns, and outliers present in a dataset. With their simplicity and effectiveness, histograms offer a convenient way to summarize and interpret large amounts of data.

By customizing various aspects such as the number of bins, colors, and labels, you can tailor the histogram to your specific needs and effectively communicate your findings. So, embrace the power of histograms and unlock a deeper understanding of your data.
