How Far Does Entropy Go? Duplicates, Confounding, Drift and Padding in Entropy-Based Detection of Malicious PE Files

This paper demonstrates that entropy-based detection of malicious PE files is severely compromised by data duplicates, size confounding, and adversarial padding, revealing that such models largely memorize known sections and can be easily evaded by appending benign-looking bytes, thereby necessitating more robust detection strategies.

Geometry of Regularized Dirichlet Likelihood: Structural Theorem, SOSC Characterization, and Certified Face-Enumeration Algorithm

This paper establishes the nonconvex geometry of the regularized Dirichlet likelihood in Evidential Deep Learning by proving the equivalence of second-order conditions to derivative positivity, deriving exact comparative statics, and introducing a certified finite-convergence face-enumeration algorithm that explains the Evidence Ceiling effect and sparsification of active sets.
