Understanding vector databases
How are Vector Embeddings Linked to Vector Databases?
Vector embeddings are mathematical representations of data in the form of multi-dimensional vectors that algorithms can easily process and analyze. Unlike traditional methods, vector embeddings place data points in a continuous space, allowing for more detailed and meaningful comparisons.
For example, in natural language processing (NLP), embeddings can capture the contextual meaning of words, enabling more sophisticated text analysis and understanding. The dimensions of these vectors represent different data features, and the vector position in space reflects the relationships and similarities between different points.
These vector embeddings are the fundamental data type that vector databases store, manage, and retrieve. The databases rely on the high-dimensional characteristics of these embeddings for quick and efficient searches.
Common types of vector embeddings include:
Word Embeddings: represent words in vector space based on their context

The variety of these vector embeddings empowers advanced AI and machine learning applications for deeper insights and more personalized, intelligent systems across various fields.
How are Embeddings Created?
Machine learning (ML) models transform raw data points into numerical representations in a high-dimensional space as vector embeddings. The models are designed to capture the meaningful features and relationships in the data to encode them as vectors.
Some popular ML models used for the creation of vector embeddings are as follows:
BERT (Bidirectional Encoder Representations from Transformers): BERT is a model that reads text in both directions (left-to-right and right-to-left) to understand the context of each word in a sentence. This helps in capturing the detailed meaning of words based on their surroundings.
GPT (Generative Pre-trained Transformer): GPT is designed to predict the next word in a sequence, which helps in generating text that is coherent and contextually relevant. It also captures the relationships between words effectively.
CNNs (Convolutional Neural Networks): Although CNNs are primarily used for image data, they can also be applied to text. CNNs analyze smaller parts of data, such as phrases or image patches, to create embeddings that capture essential features.
All these ML models rely on high-dimensional space to capture the complex relationships and semantic meanings within data. Each dimension is used to represent a different feature of the data, enabling ML models to understand and analyze various types of data for more accurate results.
For example, words with similar meanings will be placed closer together, while unrelated words will be farther apart. This spatial arrangement helps in understanding and processing data more effectively.
The Problem of High-Dimensional Data Retrieval
Since multi-dimensional vector embeddings capture complex features of data, each vector can have hundreds or thousands of dimensions. With an increase in dimensions, distances between data points become less meaningful making it difficult to navigate data.
Thus, traditional retrieval methods do not work for such complex databases. Hence, data retrieval from vector databases requires specialized algorithms and indexing techniques to find vectors efficiently. Let’s explore some indexing techniques used to navigate high-dimensional data.
Indexing Techniques in Vector Databases
Indexing techniques in vector databases are specialized methods designed to handle high-dimensional data efficiently. These techniques are optimized for performing similarity searches in vector spaces.
Here are some key indexing techniques used in vector databases:
Hierarchical Navigable Small World (HNSW) – a graph-based algorithm that creates a multi-layer navigation graph to represent the vector space, forming a network of shortcuts that narrow down the search space to a small subset of similar vectors.
Inverted File Index (IVF) – divides the vector space into clusters and creates an inverted file for each cluster. Each file records vectors belonging to a specific cluster, enabling comparison and detailed data search within clusters.
Product Quantization (PQ) – compresses vectors into a smaller representation that can be used for efficient search. It reduces the storage space and improves the query performance, making it suitable for large datasets.
Locality-Sensitive Hashing (LSH) – finds similar vectors by hashing them into buckets. Vectors that are close to each other in the vector space are likely to be hashed into the same bucket, facilitating efficient similarity searches.
Important Trade-Offs in Indexing
Indexing in vector databases is essential to achieve a balance between accuracy and speed, especially when dealing with large datasets. It results in trade-offs of retrieval speed, memory usage, and accuracy. Following are the key trade-offs in indexing:
Retrieval Speed vs. Accuracy:
Exact nearest neighbor methods guarantee high accuracy but can be slow, especially with large datasets. However, Approximate nearest neighbor (ANN) techniques offer faster retrieval times by slightly sacrificing accuracy to quickly find vectors that are close enough, making them ideal for large-scale applications.
Memory Usage vs. Speed:
Some indexing techniques, like Product Quantization (PQ), compress vectors to reduce memory usage, which can also speed up searches by making data more manageable. Meanwhile, Locality-Sensitive Hashing (LSH) hashes vectors into buckets, which speeds up the search but might require more memory to maintain the hash tables.
Hence, indexing in vector databases strikes a balance between accuracy and speed, ensuring efficient data management and scalability. By leveraging sophisticated algorithms, these databases handle large datasets while maintaining quick and reliable search performance.
Let’s look at some common search processes that rely on vector databases to produce useful and accurate results.
Vector Search – A Focused Similarity Search for Vector Databases
Similarity search is a data retrieval technique to find items that are most similar to a query input. Unlike traditional keyword searches that rely on exact matches, similarity search focuses on finding items that are alike in terms of their semantic meaning or other complex relationships.
A type of similarity search is vector search that is specifically designed for high-dimensional data represented as vector embeddings. The process relies on vector databases to execute large-scale data retrieval efficiently.
With suitable indexing techniques in these databases, it also executes faster searches. As a result, vector search is used to conduct context-aware or semantic search to user queries. Other applications of vector search include:
