2026Flow-based Generative Models (FGMs) effectively transform noise into complex data distributions. Incorporating Optimal Transport (OT) to couple noise and data during FGM training has been shown to improve the straightness of flow trajectories, enabling more effective inference. However, existing OT-based methods estimate the OT plan using (mini-)batches of sampled noise and data points, which limits their

WSDM 20262026Music streaming fraud, where bad actors artificially inflate stream counts to manipulate chart rankings and royalty payments, poses a significant threat to streaming services and legitimate content creators. Traditional fraud detection approaches struggle with a critical challenge: many legitimate edge cases, including super-fans and sleep-music sessions, exhibit activity patterns that closely mimic those

2026Despite multilingual pretraining, large language models often struggle with non-English tasks, particularly in language control — the ability to respond in the intended language. We identify and characterize two key failure modes: the multilingual transfer bottleneck (correct language, incorrect task response) and the language consistency bottleneck (correct task response, wrong language). To systematically

ECIR 20262026Personalized experiences in multimodal assistants rely on accurate user understanding, yet large-scale training for personalization remains limited by privacy constraints and data sparsity. We introduce a framework for generating Comprehensive Synthetic Personas (CSPs) and personalized synthetic training data through taxonomy-guided knowledge enrichment, in-context learning, and Chain-of-Thought (CoT) knowledge

CHI 20262026As AI agents become collaborative partners in complex tasks, understanding how agent personality affects human-AI interaction becomes critical. While recent work explores personality customization in language models, little is known about how personality affects AI coding agents. We conducted the first exploratory study investigating: if OCEAN (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism
