Advanced Memory Management with RAG and MemoRAG

5.1 Retrieval-Augmented Generation (RAG) Techniques

RAG enhances the memory layer by retrieving structured external data in real time, reducing hallucinations and improving decision-making.

For example:

• TableRAG: Focuses on schema and cell retrieval to streamline handling of large tabular datasets (Chen et al., 2024).

  • TableRAG is a framework combining schema and cell retrieval to scale language models for large tables.

  • It improves retrieval quality and efficiency, reducing token complexity in table understanding tasks.

• LongRAG: Enhancing Retrieval-Augmented Generation with Long-context LLMs:

  • The LongRAG framework redefines the architecture of Retrieval-Augmented Generation (RAG) systems by using long-context LLMs to improve the performance of the retriever and reader components.

  • Key components of LongRAG include processing long retrieval units, utilizing a long retriever to scan through these units, and employing a long reader LLM to extract detailed answers, ensuring a balanced workload.

  

5.2 Combining RAG with Tabular Data for Memory Layers

The integration of Retrieval-Augmented Generation (RAG) techniques with tabular data creates a powerful mechanism to enhance the memory layer within the ESCA framework. This approach leverages structured data from external sources alongside a model’s parametric knowledge to improve memory handling and decision-making processes.
