EVIE: Evidence-Vector-Informed Embeddings for Visual Document Retrieval

Accurate and scalable visual document retrieval (VDR) requires both fine-grained page understanding and efficient indexing, yet existing approaches struggle to achieve both. OCR-based text retrieval adds preprocessing latency and can lose visual and structural cues needed to understand complex pages. Single-vector visi...

Draft in Parallel, Condition Through Depth: Adjacent Causal Injection for Speculative Decoding

DSpine is proposed, a drafter with causal conditioning injection throughout the backbone: at every layer, gated adjacent injection writes each predecessor's predicted feature into its successor, so the causal conditioning chain unfolds over network depth while all positions update in parallel.

RSPO: Reward-Swap Policy Optimization for Multi-Turn LLM Agents

Reinforcement learning holds significant potential for training large language models to handle multi-turn interactive tasks, but directly training with outcome rewards often results in slow convergence due to the sparsity of signals and the lack of fine-grained feedback.
