We’ll walk through setting up the environment, indexing documents, querying the database, and I just saw that Facebook AI released a blog post about RAG ( Retrieval Augmented Generation: Streamlining the creation of intelligent natural language processing models) and that it is already incorporated in the HuggingFace API. Self-RAG is trained on our instruction-following corpora with interleaving passages and reflection tokens using the standard next-token prediction objective, enabling efficient and Parameters . You can load your own custom dataset with config. Contains parameters indicating which Index to build. index_name="custom" or use a canonical one (default) from the datasets library with config. The base model was trained on a dataset of text data that includes a wide variety of sources, see the Gemma 2 documentation for more details. A RAG-token model implementation. FloatTensor of Advanced RAG on Hugging Face documentation using LangChain. Utilizing their official documentation can offer insights into best practices for fine-tuning and deploying RAG models. It's a technique used in natural language processing (NLP) to improve the performance of language models by incorporating external knowledge sources, such as databases or search engines. It features a unique dual-response capability, offering both generative and extractive modes to cater to a wide range of informational needs. I also found this post in which HuggingFace explains RAG and came to know that HF implemented RAG which is awesome! My doubt is whether I could extend this functionality so that the model should do This model is a 7B Self-RAG model that generates outputs to diverse user queries as well as reflection tokens to call the retrieval system adaptively and criticize its own output and retrieved passages. Retrieval Augmented Generation (RAG) is a pattern that works with pretrained Large Language Models (LLM) and your own data to generate responses. The question encoder can be any model that can A RAG-token model implementation. FloatTensor of Parameters . FloatTensor of Retrieval-augmented generation (“RAG”) models combine the powers of pretrained dense retrieval (DPR) and sequence-to-sequence models. FloatTensor of shape (1,), optional, returned when labels is provided) — Language modeling loss. Warm. vocab_size)) — Prediction scores of the language modeling head. Hugging Face.
