Hindsight-Privileged RLVR: Single-Rollout Token Credit Without Group Sampling

Reinforcement learning with verifiable rewards (RLVR) trains language models from checked task outcomes, but assigning a terminal reward to individual reasoning tokens or actions remains difficult. Group-relative methods such as Group Relative Policy Optimization (GRPO) sample several attempts per prompt, but lose thei...

SSC-YOLOv8n-Based Surface Defect Detection for Lathe Tools

Reliable detection of subtle defects on highly reflective lathe-tool surfaces remains difficult because conventional downsampling loses high-frequency details and background reflections obscure weak defect responses. This paper proposes SSC-YOLOv8n, an improved YOLOv8n detector that integrates spatial-to-depth convolut...
