Embed: Embeddings use a specialized machine learning model (a vector-embeddings model) to convert data into numerical vectors and enable you to apply mathematical operations to assess similarities and difference
You can now chunk by token length, setting the length to a value that makes sense for your embedding model. You can also specify the tokenizer and any tokens that shouldn't be split during data chunking. The newunitparameter and query subscore definitions are found in the2024-09-01-...

What is Grounding? Grounding is the process of using large language models (LLMs) with information that is use-case specific, relevant, and not available as part of the LLM's trained knowledge. It ...
Many complex operations need to be performed - such as generating embeddings, comparing the meaning between different pieces of text, and retrieving data in real-time. These tasks are computationally intensive and can slow down the system as the size of the source data increases. To address this...
RAG comes with many configuration parameters, including which large language model to choose, how to chunk the grounding documents, and how many documents to retrieve. AutoAI automates the full exploration and evaluation of a constrained set of configuration options and produces a set of ...
Recurrent Neural Networkstake sequential input of any length, apply the same weights on each step, and can optionally produce output on each step. Overall, RNNs are a great way to build a Language Model. Besides, RNNs are useful for much more: Sentence Classification, Part-of-speech Tagging...
For specific scope embeddings, utilize SentenceWindowNodeParser to split documents into individual sentences, also capturing surrounding sentence windows. import nltk from llama_index.node_parser import SentenceWindowNodeParser node_parser = SentenceWindowNodeParser.from_defaults( window_size=3, window_metad...
As a chunk-level operation, the embedding process makes it hard to differentiate Tokens requiring increased weight, such as entities, relationships, or events. This results in low-density of effective information in the generated embeddings and poor recall. ...
Finally, YMYL is cored on the chunk level which suggests that whole system is based on embeddings. There are Gold Standard Documents There is no indication of what this means, but the description mentions “human-labeled documents” versus “automatically labeled annotations.” I wonder if this ...
