February 2, 202610 min readEvery NFL game generates millions of tracking data points from 22 RFID-equipped players. Seventy-five machine learning models running on AWS process that data in under a second, transforming football into a sport where every movement is measured, modeled, and instantly analyzed.

WSDM 20262026For e-commerce retailers, high-quality product catalogs are vital to customer experience. Yet, despite lots of data cleaning efforts, catalog quality, especially in large catalogs, remains suboptimal. This paper shows how to use unstructured brand knowledge base data as a reference and a large language model agent to automatically enhance an e-commerce retailer's catalog quality. Unlike prior methods that

NeurIPS 2025 Workshop on Mechanistic Interpretability2026Recent work has shown that fine-tuning on insecure code data can trigger an emergent misalignment (EMA) phenomenon, where models generate malicious responses even to prompts unrelated to the original insecure code-writing task. Such cross-domain generalization of harmful behavior underscores the need for a deeper understanding of the algorithms, tasks, and datasets that induce emergent misalignment. In

SAC 2025, Lecture Notes in Computer Science2026AES-GCM has seen great adoption for the last 20 years to protect data in various use-cases because of its optimal performance. It has also posed some challenges to modern applications due to its nonce, block size, and lack of key commitment. Nonce-derived schemes address these challenges by deriving a different key from random values and using GCM with the derived key. In this work, we explore efficient

2026Visual compatibility recommendation systems aim to surface compatible items (e.g. pants, shoes) that harmonise with a user-selected product (e.g., shirt). Existing methods struggle in three key aspects: they rely on global CNN representations that overlook fine-grained local cues critical for visual pairing; they force all categories into a single latent space, ignoring the fact that compatibility rules

CHIIR 20262026Taxonomies organize knowledge into hierarchical structures that support effective information seeking behaviors. However, developing taxonomies in fast-evolving domains like e-commerce remains a labor-intensive process. In this paper, we present an interactive system that assists users in expanding taxonomies through automated knowledge discovery from large text corpora. On the back end, our hybrid methods
