Langchain and Dolly: Uniting Open-Source AI Powerhouses

Open-Source AI is what the future needs

Artificial Intelligence (AI) is no longer a futuristic concept, but a reality that is transforming the world as we know it. From healthcare to finance, AI is being used to solve complex problems and improve efficiency. However, the development of AI algorithms has traditionally been a costly and time-consuming process, with only a few companies having the resources to invest in it. This is where open-source AI comes in.

Open-source AI perfectly fits into the current technological environment, where data is abundant, and innovation can thrive. It enables developers to collaborate and share their work, resulting in faster development cycles and improved algorithms. This move ensures that innovators, academics, and developers can work together in the development of AI to ensure that it benefits all in society.

One of the key benefits of open-source AI is that it democratizes access to AI technology. With open-source AI, anyone can access and use AI algorithms, regardless of their financial resources. This means that small businesses and startups can use AI to improve their products and services, without having to invest a significant amount of money in research and development.

Moreover, open-source AI enables developers to create customized solutions that meet their specific needs. This is because the code is open and can be modified to suit different applications. For example, a developer working on a healthcare project can use open-source AI to create a customized algorithm that can diagnose diseases more accurately.

Open-source AI also promotes transparency and accountability in the development of AI algorithms. With open-source AI, developers can examine the code and ensure that it is free from bias and discrimination. This is important because AI algorithms have the potential to perpetuate existing biases and discrimination if they are not developed with care.

In conclusion, open-source AI is the future of AI development. It promotes collaboration, democratizes access, enables customization, and promotes transparency and accountability. As AI continues to transform the world, it is important that it is developed in a way that benefits all in society. Open-source AI is the way to achieve this goal.

Building a Simple Chatbot for PDF’s with Langchain & Dolly for No-Cost

Building a simple chatbot has never been easier thanks to Langchain and Dolly. Here we will show you an example of a chatbot that can interact with a pdf document.

We begin by installing the needed dependencies.

Then we import our liberies and modules required for different functionalities.

The PdfReader object is created, which reads the PDF file named “Receipt.pdf” and stores it in the reader variable.

The code then initializes an empty string raw_text. It iterates over each page in the PDF using a for loop, extracts the text from each page using the extract_text() method, and checks if the extracted text is not empty. If there is text on the page, it appends it to the raw_text variable.

The CharacterTextSplitter object is created, specifying the separator as a newline character (\n), the chunk size as 1000 characters, the chunk overlap as 200 characters, and the length function as the built-in len() function. The split_text() method of the text_splitter object is then called, passing the raw_text variable as input. This function splits the text into smaller chunks based on the specified parameters and returns the resulting list of chunks stored in the text variable.

A HuggingFaceEmbeddings object is created, using the model named “sentence-transformers/all-mpnet-base-v2”. This object will be responsible for generating embeddings from the text.

The from_texts() method of the FAISS object is called, passing the text variable as input along with the embedding object. This method computes embeddings for each chunk of text and constructs a searchable index using the FAISS library.

An LLM (Large Language Model) pipeline is created using the pipeline() function from the llms package. It specifies the model as “databricks/dolly-v2-3b” and sets other configuration parameters related to hardware usage and input/output format.

A HuggingFacePipeline object is created, using the previously created LLM pipeline as the input. This object acts as a wrapper to convert the LLM pipeline into a Hugging Face pipeline, allowing it to be used in subsequent processing steps.

The load_qa_chain() function is called, passing the hf_pipeline object and specifying the chain type as “stuff”. This function loads a pre-trained question-answering chain, which combines various NLP components for question-answering tasks, such as document retrieval and answer extraction.

A query string “Summarize the receipt.” is defined. The similarity_search() method of the docsearch object (which is an instance of a vector store) is called, passing the query string as input. This method searches for similar documents in the vector store based on the query and returns a list of matching documents, stored in the docs variable.

Finally, the run() method of the chain object (the question-answering chain) is called, passing the docs and query as inputs. This method processes the input documents and the question, and returns an answer to the question based on the information in the documents. The answer is stored in the answer variable.

Try it! Here’s an Example Notebook you can use to practice with on google colab! 

As shown, the use of langchain and Dolly greatly simplifies the process of building a language processing pipeline for tasks such as document extraction and question-answering. With langchain, various components like text splitting, embeddings, and vector search can be easily integrated into the pipeline, streamlining the development process. Additionally, Dolly, as a powerful pre-trained language model, enhances the capabilities of the pipeline, allowing for accurate and context-aware question-answering. The combination of langchain and Dolly provides a user-friendly and efficient framework for NLP tasks, enabling developers to quickly implement sophisticated language processing solutions.
