AI & ML Research

Developers are refining how AI agents interact with external information and actions. Tool calling allows large language models to decide which functions to execute, bridging the gap between abstract reasoning and real-world data retrieval or task completion. In document processing, techniques such as Retrieval Augmented Generation (RAG) are being adapted to reconstruct structural metadata, like a table of contents, for PDFs that lack native outlines. This enables more precise document analysis by allowing AI to scope its responses by specific sections rather than processing entire documents.
