  • Box-Constrained Softmax Function and Its Application for Post-Hoc Calibration

    Box-Constrained Softmax Function and Its Application for Post-Hoc Calibration arXiv:2506.10572v1 Announce Type: new Abstract: Controlling the output probabilities of softmax-based models is a common problem in modern machine learning. Although the $mathrm{Softmax}$ function provides soft control via its temperature parameter, it lacks the ability to enforce hard constraints, such as box constraints, on output probabilities,…

  • Sparsity-Based Interpolation of External, Internal and Swap Regret

    Sparsity-Based Interpolation of External, Internal and Swap Regret arXiv:2502.04543v1 Announce Type: new Abstract: Focusing on the expert problem in online learning, this paper studies the interpolation of several performance metrics via $phi$-regret minimization, which measures the performance of an algorithm by its regret with respect to an arbitrary action modification rule $phi$. With $d$ experts…
