类R1训练不再只看结果对错!港中文推出SophiaVL-R1模型
机器之心· 2025-06-06 09:36
DeepSeek-R1 爆火后,类 R1 的结果奖励训练范式在各领域掀起了推理热潮。基于规则的结果奖励实现简单、判断严格。但是,这真的够了吗? 在推理任务中,如果我们只是用「结果对错」来奖励模型,那模型就很可能学会了「靠捷径答题」。 这种模式下,模型的「正确思考策略」没有完全建立起来,它甚至会因为一次「瞎蒙对」的奖励,而在之后反复强化错误策略,越走越偏。 为了解决这个问题,港中文联合上海人工智能实验室团队发布了多模态推理模型 SophiaVL-R1,它在类 R1 强化学习训练框架上做了一次关键进化:不再 只奖励结果是否正确,而是将「思考过程」也纳入奖励体系。 这一套设计不仅能让模型学会更通用、更靠谱的推理策略,还显著提升了泛化能力——在多个数学和通用多模态基准测试中,SophiaVL-R1-7B 甚至击败 了参数量是其 10 倍的 LLaVA-OneVision-72B 模型。 目前,研究团队已将所有模型、数据和代码开源。 思考过程也要评分,才是好模型 SophiaVL-R1 的关键突破点,就在于它引入了「思考奖励」机制 —— 不再只看答案对不对,而是开始评估模型整个推理过程是否合理、连贯、靠谱。 论文链接: ...
