AI papers probe softmax function's statistical and geometric limits

Two new arXiv papers explore the statistical and geometric properties of the softmax function, a core component in many AI models. The first paper, "When Softmax Fails at the Top," introduces WEINCE, a modification to contrastive learning objectives that improves performance on vision benchmarks by addressing statistical misalignments. The second paper, "The Information Geometry of Softmax," delves into how AI systems encode semantic structure in their representation spaces, proposing "dual steering" as a method to control and stabilize concept manipulation in representations that define softmax distributions. AI

IMPACT These papers offer theoretical insights into the fundamental mechanisms of AI models, potentially leading to more robust and controllable representations.

    When Softmax Fails at the Top: Extreme Value Corrections for InfoNCE

    arXiv:2606.00262v1 Announce Type: cross Abstract: InfoNCE is the standard contrastive learning objective, but its softmax form is not only a computational convenience: it also encodes a statistical assumption about how the top-scoring example is selected. Using extreme value theo…

    The Information Geometry of Softmax: Probing and Steering

    arXiv:2602.15293v2 Announce Type: replace-cross Abstract: This paper concerns the question of how AI systems encode semantic structure into the geometric structure of their representation spaces. The motivating observation is that the natural geometry of these representation spac…

    InfoNCE is the standard contrastive learning objective, but its softmax form is not only a computational convenience: it also encodes a statistical assumption about how the top-scoring example is selected. Using extreme value theory, we show that this assumption is often misalign…
