新的贝叶斯风洞方法使 Transformer 能够进行模型选择

研究人员开发了一种名为贝叶斯风洞 (Bayesian Wind Tunnels) 的新方法,使 Transformer 能够执行贝叶斯模型选择,从数据中识别正确的假设类别。使用无不动点对合,一个 2.8M 参数的 Transformer 在与真实后验概率的一致性方面接近最优。该研究还确定了一个关键条件,即在判别统计中进行算术运算对于成功的模型选择是必要的,即使在扩展到 316M 参数时,这一边界仍然存在。对前沿 LLM 的探测揭示了定性的贝叶斯行为,但存在显著的校准差距。 AI

影响 这项研究可能带来更复杂的 AI 模型,使其能够从数据中辨别正确的假设,从而可能提高其推理和决策能力。
