arXiv:2603.06652v2 Announce Type: replace-cross Abstract: Reinforcement learning has recently improved the reasoning ability of Large Language Models and Multimodal LLMs, yet prevailing reward designs emphasise final-answer correctness and consequently tolerate process hallucinations--cases where models reach the right answer while misperceiving visual evidence. We address this process-level misalignment with PaLMR, a framework that aligns not only outcomes but also the reasoning process itself. PaLMR comprises two complementary components: a perception-aligned data layer that constructs proce
The increasing sophistication of Multimodal LLMs necessitates more robust reasoning capabilities, moving beyond simple correct answers to ensuring the process itself is aligned with human understanding.
This development indicates a critical step towards more reliable and trustworthy AI systems, especially in applications requiring verifiable reasoning rather than just accurate outcomes.
AI models will move towards being judged not only on output correctness but also on the logical integrity of their internal reasoning process, potentially reducing 'process hallucinations'.
