RecSys 20262026Multi-agent collaborative filtering systems coordinate autonomous LLM-powered user and item agents through natural-language interaction to refine preferences and generate recommendations. These systems inherit vulnerabilities from both their data-driven nature and multi-agent interactions, which manifest in distinct ways. Understanding how connectivity modulates vulnerability in these systems could facilitate

ACM SIGSPATIAL 20262026Geospatial analysis traditionally requires specialized GIS expertise, complex software interfaces, and significant manual effort to orchestrate data from heterogeneous sources. We present Fangorn, an agentic platform that enables analysts to perform sophisticated geospatial intelligence operations through natural language conversation. Fangorn combines a modular tool ecosystem based on the Model Context

ACM SIGSPATIAL 2026, International Journal of Geographical Information Science2026We present a nonparametric method for multi-modal trajectory prediction that requires no GPU, fits in seconds on CPU, and matches or exceeds a 57M-parameter transformer. The method builds a transition table of historical state-to-next-position pairs and retrieves neighbors using a product kernel over spatial proximity, bearing, speed, and temporal context. Two inference modes operate over this shared representation

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)
