Learning robust representations of authorial style is crucial for authorship attribution and AI-generated text detection. However, existing methods often struggle with content-style entanglement, where models learn spurious correlations between authors’ writing styles and topics, leading to poor...

Multi-hop reasoning remains a fundamental challenge for Retrieval-Augmented Generation (RAG) systems. Recent approaches—from adaptive retrieval to agentic pipelines—struggle to maintain coherent intermediate reasoning states as chains grow longer. We introduce State-Aware RAG, a framework that ad...
