CEC-Zero: Zero-Supervision Character Error Correction with Self-Generated Rewards

AAAI 2026technical

Large-scale Chinese spelling correction (CSC) remains critical for real-world text processing, yet existing LLMs and supervised methods lack robustness to novel errors and rely on costly annotations. We introduce CEC-Zero, a zerosupervision reinforcement learning framework that addresses this by ena

Path Matters: Unveiling Geometric Implicit Bias via Curvature-Aware Sparse View Optimization

ICLR 2026poster

3D Gaussian Splatting (3DGS) has recently emerged as a powerful approach for novel view synthesis by reconstructing scenes as sets of Gaussian ellipsoids. Despite its success in scenarios with dense input images, 3DGS faces critical challenges in sparse view settings, often resulting in geometric in…

Whose Instructions Count? Resolving Preference Bias in Instruction Fine-Tuning

NeurIPS 2025poster

Instruction fine-tuning (IFT) has emerged as a ubiquitous strategy for specializing large language models (LLMs), yet it implicitly assumes a single, coherent "ground-truth" preference behind all human-written instructions. In practice, annotators differ in the styles, emphases, and granularities th…
