ICDE 20272027A fundamental challenge of vector search is achieving consistently high recall while minimizing computational costs. Fixed search parameters cause significant performance variance across queries, and conventional evaluation on average recall masks these per-query disparities. We introduce QASP (Query-Adaptive robust vector Search Policy), which predicts the complete recall progression curve per query via

IAAI 20272027Alexa+ devices with screens display animated icons during conversations to visually reinforce what is being said. The original set of these icons was hand-drawn by designers one at a time, a process that produces polished results but is time-consuming and cannot scale to the range of topics encountered in open-ended conversation. We describe an automated pipeline, deployed in production, that generates

2026Points-of-Interest (POI) search, the task of retrieving and ranking geographically situated entities in response to a query issued from a specific location, underpins major mapping and navigation services. We present POI Search Suite (POISS), the first large-scale dataset designed for this task, pairing over 300K geo-anchored natural language queries across 7 languages and 14 locales with more than 4M graded

2026 IEEE Sensor Data Fusion: Trends, Solutions, Applications2026Transformer architecture has shown great success in many challenging problems such as natural language processing. It excels at discovering features and correlations in large amounts of data. Sensor fusion is another technology that requires this kind of processing power and reasoning capability. Researchers have applied transformer architecture in sensor fusion model technologies. However, most of them

2026Large Language Model (LLM) based conversational systems generate vast interaction logs containing critical diagnostic signals such as failure modes and safety violations. However, the cross-turn dependencies, implicit state, and topic drift inherent to these conversations (Yang et al., 2025b; Mo et al., 2024) defeat dense retrieval, whose lone embedding cannot concurrently encode discrete structured constraints
