FraudBench Benchmarks Adversarial Robustness in Financial Risk Assessment
This paper introduces FraudBench, a protocol-sensitive benchmark for evaluating the adversarial robustness of machine learning models in financial fraud and credit-risk detection. It demonstrates that robustness conclusions are highly dependent on how domain-specific constraints and attacker capabilities are incorporated into the evaluation protocol.
Persistent Cross Entropy Extends Topological Data Analysis
This paper introduces Persistent Cross Entropy (PCE), a novel extension of cross-entropy to persistence diagrams, which are used in topological data analysis. PCE bridges different event spaces of diagrams using an induced probability, enabling new applications like distinguishing diagrams with similar persistent entropy and separating causal directions in dynamical systems.
Bridging Numerical PDE Solvers and Neural Emulators for Faster Simulation
This thesis explores the deep connections between traditional numerical solvers for Partial Differential Equations (PDEs) and neural emulators, arguing that they are more alike than different. It proposes that insights can flow profitably in both directions, leading to faster and more efficient scientific and engineering simulations.
