How CISOs can defend against Scattered Spider ransomware attacks
CISOs should fortify help desk and employee defenses, enhance intrusion detection and tracking capabilities, and recognize that paying ransoms is not a viable strategy.

Bipartite Ranking From Multiple Labels: On Loss Versus Label Aggregation
Bipartite ranking is a fundamental supervised learning problem, with the goal of learning a ranking over instances with maximal Area Under the ROC Curve (AUC) against a single binary target label. However, one may often observe multiple binary target labels, e.g., from distinct human annotators. How can one synthesize such labels into a single coherent ranking? In this work, we formally analyze two approaches to this problem -- loss aggregation and label aggregation -- by characterizing their B…

Stability and Extension of Steady and Ranging Persistence
Persistent homology is a topological data analysis tool that has been widely generalized, extending its scope outside the field of topology. Among its extensions, steady and ranging persistence was developed to study a wide variety of graph properties. Precisely, given a feature of interest on graphs, it is possible to build two types of persistence (steady and ranging persistence) that follow the evolution of the feature along graph filtrations. This study extends steady and ranging persistenc…

"the squirrels' busy year": ein bilderbuch nach dem motto "a first science storybook", aber ich finde es leider etwas "underwhelming", was die erzählten jahreszeitencharakteristika angeht, und offenbar futtern eichhörnchen – in diesem fall: grauhörnchen – fast nur eicheln, was ja nicht stimmt. schade, hätte man mehr draus machen können unter so einem tollen titel.

RADAR: Recall Augmentation through Deferred Asynchronous Retrieval
Modern large-scale recommender systems employ multi-stage ranking funnel (Retrieval, Pre-ranking, Ranking) to balance engagement and computational constraints (latency, CPU). However, the initial retrieval stage, often relying on efficient but less precise methods like K-Nearest Neighbors (KNN), struggles to effectively surface the most engaging items from billion-scale catalogs, particularly distinguishing highly relevant and engaging candidates from merely relevant ones. We introduce Recall A…
