Annealed Langevin dynamics replaces biased reverse-SDE sampling for compositional SBI scores with controllable bridging densities, yielding explicit hyperparameter rules; Linhart et al.'s formulation allows larger steps and fewer iterations than Geffner et al.'s in Gaussian settings and generalizes
Reinforcement learning for code optimization fails due to noisy, sparse execution-time rewards, so a calibrated three-stage pipeline improves strict pass rates by up to 125% while preserving correctness.
Optimal transport characterizes relaxed fair regression via smooth population-wide or exact subset parity penalties across aware and unaware settings, and proposed algorithms match or exceed state-of-the-art benchmarks.
FedForest proposes a federated random forest using aggregated statistics to approximate centralized splits under heterogeneous data, enabling personalized client-indicator splits with near-centralized accuracy and low communication cost.
Lumberjack improves differentially private random forests via heavy hitter pruning of deep trees, achieving state-of-the-art privacy-utility trade-offs.
Causal inference framing of membership inference attacks defines memorization as training inclusion effects, reveals interference and distribution-shift biases, and yields reliable estimators without retraining.
A Cramér-von Mises fairness regularizer with O(B log B) complexity penalizes prediction-sensitive attribute dependence during training, achieving competitive fairness-utility trade-offs with lower overhead.
