Multiclass Calibration Assessment and Recalibration of Probability Predictions via the Linear Log Odds Calibration Function
Multiclass Calibration Assessment and Recalibration of Probability Predictions via the Linear Log Odds Calibration Function arXiv:2602.18573v1 Announce Type: new Abstract: Machine-generated probability predictions are essential in modern classification tasks such as image classification. A model is well calibrated when its predicted probabilities correspond to observed event frequencies. Despite the need for multicategory recalibration methods, existing…

Rate-optimal community detection near the KS threshold via node-robust algorithms
Rate-optimal community detection near the KS threshold via node-robust algorithms arXiv:2511.16613v1 Announce Type: new Abstract: We study community detection in the emph{symmetric $k$-stochastic block model}, where $n$ nodes are evenly partitioned into $k$ clusters with intra- and inter-cluster connection probabilities $p$ and $q$, respectively. Our main result is a polynomial-time algorithm that achieves the minimax-optimal…
