CIKM 20262026Many business and clinical decisions depend on the conditional average treatment effect (CATE) of each of several continuous treatments that move together: advertising spend and discount levels driven by the same campaign, or drug doses adjusted in a common protocol. Several estimator families produce CATE at every query point with a confidence interval, including meta-learners, doubly robust learners,

2026Product families in large product catalogs suffer from inconsistencies such as duplicates and unit mismatches that degrade customer experience. Detecting these requires reasoning over multiple error types across lengthy product listings, where LLM classification quality degrades due to long-context limitations. We address this by decomposing detection into focused sub-tasks that reduce context and isolate

2026Production Retrieval-Augmented Generation (RAG) systems serve repeated queries over evolving document corpora under user-specific access constraints. Standard pipelines perform full retrieval and generation for every request, wasting computation on recurring queries. Naive caching reduces latency but introduces safety failures: stale evidence from updated documents, unauthorized content crossing access

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

2026Knowledge distillation has become a crucial technique to transfer the capacities of large language models (LLMs) to smaller, more efficient models for practical deployment. While recent work exploits rich information from intermediate states of the teacher model for more effective knowledge transfer, imperfect knowledge from the teacher can also mislead student learning, restricting the student's generalization
