馃摎 A parent document retriever is useful in RAG and differs from LLMs in terms of embeddings for retrieval.
馃挕 RAG can extract relevant information from a set of documents by using a quality model and trimming out irrelevant bits.
馃攳 In conventional RAG, documents are split into parts and embeddings are used to represent the semantic details of each part.
馃挵 When comparing different products or earnings, using multiple figures and descriptions leads to more general embeddings.
馃攷 Parent document retrievers help create more specific embeddings by splitting the original document into parent and child chunks.
馃 Using parent document retrievers allows for a comparison between different products and a larger context for analysis.
馃摎 Parent document retrievers pass back the parent documents instead of just the child documents.
馃挕 Using a larger context in the parent document allows the language model to take advantage of the extra information.
馃攳 The parent document retriever can be used in two ways: returning full documents or returning bigger chunks from smaller chunks.
馃攳 The video discusses the use of a parent document retriever in advanced RAG models.
馃挕 Different types of embeddings, such as BGE and OpenAI embeddings, can be used for retrieval.
馃摎 The retrieval process involves splitting documents into smaller chunks and storing them in memory.
The Advanced RAG 02 - Parent Document Retriever allows us to retrieve smaller chunks of a document and also their corresponding parent documents.
By using the vector store similarity search feature, we can find matching documents based on a specific query.
There are two methods for retrieving documents: retrieving the entire document in one shot or retrieving larger chunks to avoid processing extremely large documents.
馃攽 The parent document retriever is introduced, allowing for multiple layers of documents that are split into big chunks.
馃З The sub docs are smaller and more specific, providing relevant information when searching.
馃攳 The big chunks retriever retrieves relevant documents, which are parts of the blog posts, based on the search query.
馃攽 The parent document retriever is a useful tool for obtaining fine-grained information and providing a larger context for language models.
馃挕 By utilizing the retriever, developers can bridge the gap between prototype and production in their projects.
馃幆 The retriever can be applied in various scenarios where specific embeddings and coherent answers are needed.
