2026Optical Character Recognition (OCR) is a fundamental task for digitizing information, serving as a critical bridge between visual data and textual understanding. While modern Vision-Language Models (VLM) have achieved high accuracy in this domain, they predominantly rely on autoregressive decoding, which becomes computationally expensive and slow for long documents as it requires a sequential forward pass

2026Creating authentic agentic twins of mobile users through realistic user behavior simulation is critical to truly understand and anticipate customer needs at scale. Toward this, we introduce Agentic Twins of Mobile Users (AgenTwin), an end-to-end framework for high-fidelity mobile user simulation that addresses four key limitations in existing approaches: subjective decision-making diversity, scalable experience

EuroSys 20262026Modern large language models rely on attention mechanisms that attend to all tokens in a sequence, resulting in quadratic computational complexity that limits scalability. While sparse attention reduces compute and memory requirements by attending to only important tokens, implementing these techniques presents significant challenges due to the complexity of combining static and dynamic sparse patterns

CIKM 20262026Generative, LLM-powered search demos beautifully, then collides with production: hard latency deadlines, a bill that scales with traffic, and near-zero tolerance for failure. This experience report argues that the hidden specification for production AI search is the customer's expectation of difficulty—how hard a request looks to them—which sets both the quality they demand and the latency they tolerate

CIKM 20262026On modern e-commerce stores, customers consume ordered slates of heterogeneous product media—such as images, videos, and 3D renders—before making purchase decisions. Existing media-ranking systems often optimize myopic engagement proxies such as clicks or dwell time, even though product media assets are cooperative informational components of the same item that together help customers find the information
