As the capabilities of Generative AI (GenAI) models advance, teams must assess security & safety risks before deployment to prevent potential harm. Teams developing GenAI models face the dual challenge of improving both performance and security & safety through specialized testing protocols. The rapid pace of AI development means teams often lack proper security & safety evaluation tools or prioritize performance

RecSys 20262026We report a practical lesson from building a GPU-free explainable-recommendation serving stack: explanations are pre-generated offline into a per-item candidate pool, and a small CPU-resident model selects one at request time. Every candidate in the pool of size K carries an offline BERTScore-F1 label against a reference explanation, so we compare a pairwise learning-to-rank model (LightGBM LambdaRank)

RecSys 20262026One of the most challenging problems entertainment live-streaming services face in recommendation systems is that user behaviors are sparse and delayed, and interaction data exhibits bias for different user segments. Unlike e-commerce applications where user actions follow linear sequences, live-streaming viewers engage in multiple concurrent behaviors of watching, chatting, following, and spending, each

CIKM 20262026Static pruning is widely used to accelerate sparse neural retrieval, yet existing studies each validate their conclusions within a single custom pipeline, leaving it unclear which findings transfer to modern engines with different index organizations and dynamic pruning mechanisms. We present the first cross-engine pruning portability study, evaluating static pruning strategies across three engines—a controlled

ACM CODI-CRAC 20262026In this work, we propose a method for dialog simulation to gather high-quality open-domain, multi-turn question answering conversations . The simulation is grounded on Stack Exchange posts and motivated by computational discourse theory. We first convert forum posts into structured directed graphs; then, different traversals through the graph represent possible conversational trajectories. Our proposed
