In our case we can download Azure functions documentation from here and save it in data/documentation folder. GPT-3.5 will generate an answer that accurately answers the question.Feed that into GPT-3.5 as context in the prompt.When a user asks a question, we will use the FAISS vector index to find the closest matching text.Store all of the embeddings in a vector store (Faiss in our case) which can be searched in the application.

Index the pdf document (azure functions documentation), split the document into chunks, indexing all of the text creating embeddings.Then answer arbitrary questions by referencing the documentation text. Let’s build a tool that can read developers documentation – in this case Azure Functions Documentation as PDF. In this article, we will explore the concept of vector databases and their applications in various fields. The number of dimensions in each vector can vary widely, ranging from tens to thousands, depending on the complexity and granularity of the data.

These vectors are mathematical representations of the features or attributes of the data being stored.

For visualization of concepts and relations between categories.Įxample of clustering of vector values for sentencesĪ vector database is a specialized type of database that stores data as high-dimensional vectors.

As input to a machine learning model for a supervised task.

These can be used to make recommendations based on user interests or cluster categories.

Finding nearest neighbours in the embedding space.

Neural network embeddings have 3 primary purposes:

Neural network embeddings are useful because they can reduce the dimensionality of categorical variables and meaningfully represent categories in the transformed space. In the context of neural networks, embeddings are low-dimensional, learned continuous vector representations of discrete variables. EmbeddingsĪn embedding is a mapping of a discrete, categorical variable to a vector of continuous numbers. Vector databases are optimized for doing quick searches in high dimensional spaces. Memory refers to persisting state using VectorStores. “ Agents” can take actions based on inputs along the way instead of a hardcoded deterministic sequence. In some tasks, however, the sequence of calls is often not deterministic and the next step will depend on the user input and the response in the previous steps. If you have a mix of text files, PDF documents, HTML web pages, etc, you can use the document loaders in Langchain.Īgents involve an LLM making decisions about which actions to take, taking that action, seeing an observation, and repeating that until done.Īs we explained before, chains can help chain together a sequence of LLM calls. LangChain’s Document Loaders and Utils modules facilitate connecting to sources of data and computation. Examples include summarization of long pieces of text and question/answering over specific data sources. Chains can also be simple, such as reading user input, constructing a prompt, and generating a response.ĭata Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for use in the generation step. For instance, you may need to retrieve data from a particular URL, summarize the returned text, and answer questions using the generated summary. It supports a variety of LLMs, including OpenAI, LLama, and GPT4All.Ĭhains in LangChain involve sequences of calls that can be chained together to perform specific tasks. This includes prompt management, prompt optimization, a generic interface for all LLMs, and common utilities for working with LLMs like Azure OpenAI. The langchain library is comprised of different modules: With LangChain, you can connect to a variety of data and computation sources and build applications that perform NLP tasks on domain-specific data sources, private repositories, and more.Īs of May 2023, the LangChain GitHub repository has garnered over 42,000 stars and has received contributions from more than 270 developers worldwide. Its primary goal is to create intelligent agents that can understand and execute human language instructions. Harrison Chase's LangChain is a powerful Python library that simplifies the process of building NLP applications using large language models. In this article, I will introduce LangChain and explore its capabilities by building a simple question-answering app querying a pdf that is part of Azure Functions Documentation.
