Echoes, Not Amnesia: Teaching GUI Agents to Remember What Worked

A mechanism-first look at EchoTrail-GUI, a framework that turns stateless GUI agents into memory-augmented systems by collecting, filtering, retrieving, and reusing successful operating traces.

XAI, But Make It Scalable: Why Experts Should Stop Writing Rules

A hybrid XAI paper shows why scalable explainability may depend less on experts writing every rule and more on experts identifying the few exceptions machines miss.
