Retrieval-augmented generation (RAG) is a technique that grants generative artificial intelligence models information retrieval capabilities. It modifies interactions with a large language model (LLM) so that the model responds to user queries with reference to a specified set of documents, using this information to augment information drawn from its own vast, static training data.
LangChain was launched in October 2022 as an open source project by Harrison Chase, while working at machine learning startup Robust Intelligence. The project quickly garnered popularity, [3] with improvements from hundreds of contributors on GitHub, trending discussions on Twitter, lively activity on the project's Discord server, many YouTube tutorials, and meetups in San Francisco and London.
The original code property graph was implemented for C/C++ in 2013 at University of Göttingen as part of the open-source code analysis tool Joern. [14] This original version has been discontinued and superseded by the open-source Joern Project, [ 15 ] which provides a formal code property graph specification [ 16 ] applicable to multiple ...
In words, [| ~ ()] is the log-likelihood of outputting , if the model first encodes the input into the vector (), then prepend the vector with the "prefix vector" ~, then apply . For prefix tuning, it is similar, but the "prefix vector" Z ~ {\displaystyle {\tilde {Z}}} is pre-appended to the hidden states in every layer of the model.
The safetensors format was developed around 2021 to solve problems with the pickle format in python. It was designed for saving and loading tensors. Compared to pickle format, it allows lazy loading, and avoids security problems. [22] After a security audit, it became the default format in 2023. [23] The file format:
In information retrieval, Okapi BM25 (BM is an abbreviation of best matching) is a ranking function used by search engines to estimate the relevance of documents to a given search query.
Popular datasets for code generation include two trading card datasets that link the text that appears on cards to code that precisely represents those cards. One was constructed linking Magic: The Gathering card texts to Java snippets; the other by linking Hearthstone card texts to Python snippets. [ 33 ]
Rag (typography), the ragged edge of a block of text; Recombination-activating gene, encoding enzymes RAG-1 and RAG-2; RAG rating (Red, Amber, Green), a traffic light rating system; Rags (dog) (1916–1936), 1st Infantry Division (United States) mascot in World War I; The Rag (club), alternative name for the Army and Navy Club in London
