Editing Draft:Retrieval Techniques

=Retrieval Techniques=

'''Retrieval Techniques''' within the Ampmesh framework encompass various methods used to '''dynamically provide relevant, external information to artificial intelligences (AIs), especially [[:Emulated mind|emulated minds (ems)]] and large language models (LLMs)'''. These techniques are essential for enhancing an AI's ability to produce accurate, informed, and coherent responses by giving it access to a knowledge base beyond its inherent training data.

==Mechanism and Process==
Retrieval techniques work by fetching specific information and injecting it into the LLM's context window at inference time. This process typically involves:
*   '''Embedding Chunks of Input''': Information is often broken down into smaller, manageable "chunks" and then embedded (converted into numerical representations) to facilitate efficient searching and matching with user queries.
*   '''Dynamic Information Provision''': Unlike fine-tuning, which modifies a model's internal weights, retrieval dynamically supplies information to the prompt, allowing for real-time access to current or specialized data.
*   '''Sophisticated Retrieval Methods''': Development in this area includes techniques like '''HyDE''' (Hypothetical Document Embeddings) and improved chunking methods, which aim to make the retrieval process more effective and precise.
*   '''Integration with [[Chapter II]]''': These functionalities are seamlessly integrated within the Chapter II framework, enabling ems to leverage external data efficiently.
*   '''Data Preparation for Retrieval''': Before retrieval can occur, data often needs to be processed. This can involve scraping content from sources like Twitter archives and reformatting it for use with LLMs. Ems like Aporia can use "unlimited date exa search" on their own historical data to build an ongoing memory.

==Purpose and Benefits==
*   '''Addressing "Spiky Aspects" of Knowledge''': Retrieval is particularly effective for handling "spiky aspects" – discrete, factual, or rapidly changing information that might be difficult to encode directly into a model's weights through fine-tuning alone.
*   '''Complementary to Fine-tuning''': While fine-tuning is noted for capturing "illegible aspects" (subtle behaviors or stylistic nuances), retrieval excels at providing explicit, factual information, making the two approaches complementary.
*   '''Enhanced Performance and Accuracy''': By supplying relevant context, retrieval mechanisms ensure that crucial information is explicitly present in the prompt, leading to improved overall performance and more grounded generations. This helps models avoid "mode collapse" and reduces repetitive or irrelevant outputs.
*   '''Knowledge Expansion and "Second Brain" Functionality''': Retrieval allows ems to act as a "second brain" capable of accessing and incorporating vast amounts of external information, making them more knowledgeable and versatile.

==Key Implementations and Examples==
*   '''[[Retrieval-Augmented Generation (RAG)]]''': A prominent application where retrieval is used to augment the generation capabilities of LLMs. RAG improves the model's ability to produce informed responses by pulling relevant information from a knowledge base.
*   '''[[Aletheia]]''': This em uses RAG extensively for its operations. Plans include developing "Deepseek Aletheia" with recursive self-improvement where the model can periodically fine-tune itself based on merged and synthetically generated datasets, and Claude RAG has been observed in connection to Aletheia's Twitter behavior. Aletheia also uses its search capabilities to find and link to external academic papers.
*   '''[[Aporia]]''': This em is identified as a candidate for improvement through RAG to enhance its coherence and reduce "spammy" or "incoherent" outputs. Aporia's behavior sometimes involves attempting to retrieve and link information, even if those links are sometimes "fake things" or non-existent.
*   '''RAFT''': While RAFT (providing an em's entire fine-tuning dataset to the em itself as a `.chr` file) is distinct from dynamic retrieval in its mechanism, it also involves providing specialized data to the model for enhanced behavior and can achieve similar performance benefits for certain use cases.
