On the Objective and Feature Weights of Minkowski Weighted k-Means

arXiv:2603.25958v1 Announce Type: new Abstract: The Minkowski weighted k-means (mwk-means) algorithm extends classical k-means by incorporating feature weights and a Minkowski distance. Despite its empirical success, its theoretical properties remain insufficiently understood. We show that the mwk-means objective can be…

Nonmyopic Global Optimisation via Approximate Dynamic Programming

arXiv:2412.04882v2 Announce Type: replace Abstract: Global optimisation to optimise expensive-to-evaluate black-box functions without gradient information. Bayesian optimisation, one of the most well-known techniques, typically employs Gaussian processes as surrogate models, leveraging their probabilistic nature to balance exploration and exploitation. However,…

Second-Order, First-Class: A Composable Stack for Curvature-Aware Training

arXiv:2603.25976v1 Announce Type: new Abstract: Second-order methods promise improved stability and faster convergence, yet they remain underused due to implementation overhead, tuning brittleness, and the lack of composable APIs. We introduce Somax, a composable Optax-native stack that treats curvature-aware training…

Cascading Bandits With Feedback

arXiv:2511.10938v2 Announce Type: replace Abstract: Motivated by the challenges of edge inference, we study a variant of the cascade bandit model in which each arm corresponds to an inference model with an associated accuracy and error probability. We analyse four…

QuitoBench: A High-Quality Open Time Series Forecasting Benchmark

arXiv:2603.26017v1 Announce Type: new Abstract: Time series forecasting is critical across finance, healthcare, and cloud computing, yet progress is constrained by a fundamental bottleneck: the scarcity of large-scale, high-quality benchmarks. To address this gap, we introduce textsc{QuitoBench}, a regime-balanced benchmark…

PathFinder: Advancing Path Loss Prediction for Single-to-Multi-Transmitter Scenario

arXiv:2512.14150v3 Announce Type: replace Abstract: Radio path loss prediction (RPP) is critical for optimizing 5G networks and enabling IoT, smart city, and similar applications. However, current deep learning-based RPP methods lack proactive environmental modeling, struggle with realistic multi-transmitter scenarios, and…

cc-Shapley: Measuring Multivariate Feature Importance Needs Causal Context

arXiv:2602.20396v3 Announce Type: replace Abstract: Explainable artificial intelligence promises to yield insights into relevant features, thereby enabling humans to examine and scrutinize machine learning models or even facilitating scientific discovery. Considering the widespread technique of Shapley values, we find that…
