Biomedical Question Answering over Custom Datasets with 🦜️🔗 LangChain and DBRX Instruct from Hugging Face 🤗
Large Language Models produce some amazing results, chatting and answering questions with seeming intelligence. But how can you get LLMs to answer questions about your specific datasets? Imagine answering questions based on your company's knowledge base, docs or Slack chats. The good news is that this is easy with open-source tooling and LLMs. This example shows how to apply LangChain, Hugging Face transformers, and open source LLMs such as DBRX from Databricks. This example can make use of any text-generation LLM or even OpenAI with minor changes. In this case, the data set is a set of freely available published papers in PDF format about cystic fibrosis from PubMed, but could be any corpus of text.

Getting started
Although specific solutions can be downloaded as .dbc archives from our websites, we recommend cloning these repositories onto your databricks environment. Not only will you get access to latest code, but you will be part of a community of experts driving industry best practices and re-usable solutions, influencing our respective industries.
<img width="500" alt="add_repo" src="https://user-images.githubusercontent.com/4445837/177207338-65135b10-8ccc-4d17-be21-09416c861a76.png">To start using a solution accelerator in Databricks simply follow these steps:
- Clone solution accelerator repository in Databricks using Databricks Repos
- Attach the
RUNMEnotebook to any cluster and execute the notebook via Run-All. A multi-step-job describing the accelerator pipeline will be created, and the link will be provided. The job configuration is written in the RUNME notebook in json format. - Execute the multi-step-job to see how the pipeline runs.
- You might want to modify the samples in the solution accelerator to your need, collaborate with other users and run the code samples against your own data. To do so start by changing the Git remote of your repository to your organization’s repository vs using our samples repository (learn more). You can now commit and push code, collaborate with other user’s via Git and follow your organization’s processes for code development.
The cost associated with running the accelerator is the user's responsibility.
