RAGBooster
RAGBooster improves the performance of retrieval-based large language models by learning which data sources are important to retrieve high quality data.
We provide an example notebook that shows how we boost RedPajama-INCITE-Instruct-3B-v1, a small LLM with 3 billion parameters to be on par with OpenAI's GPT3.5 (175 billion parameters) in a question answering task by using Bing websearch and ragbooster:

Furthermore, we have an additional example notebook, where we demonstrate how to boost a tiny qa model to get within 5% accuracy on GPT3.5 on a data imputation task:

Core classes
At the core of RAGBooster are RetrievalAugmentedModels, which fetch external data to improve prediction quality. Retrieval augmentation requires two components:

A retriever, which retrieves external data for a prediction sample. We currently only implement a BingRetriever, which queries Microsoft's Bing Websearch API.
A generator, which generates the final prediction from the prediction sample and the external data. This is typically a large language model. We provide the Generator interface, which makes it very easy to leverage LLMs available via an API, for example from OpenAI.

Once you defined your retrieval-augmented model, you can leverage RAGBooster to boost its performance by learning the data importance of retrieval sources (e.g., domains in the web). This often increases accuracy by a few percent.
