Title & Speakers Event
Alexy Khrabrov – AI Community Architect @ Neo4j

ASKG is a knowledge graph of all the MCP servers on the internet, scraped and loaded into a Neo4j instance. It has its own MCP server that allows agents to put together agent calls for various data pipelines. ASKG is a project of the AIliance and you can contribute at github.com/oakstack/askg

Lazar Obradovic – Lead Data Scientist @ Cognee

Cognee organizes your data into AI memory. It builds structured AI memory by transforming raw data into a modular, queryable knowledge graph powered by embeddings. Like any complex system, it depends on many hyperparameters that shape performance in subtle ways. This talk shows how systematic tuning can improve AI memory, what current evaluation methods reveal (and miss), and why future progress will depend as much on better evaluation and optimization as on new architectures.
