SIGIR 20262026Music search at the scale of Amazon Music presents a unique challenge: queries frequently deviate from indexed metadata due to misspellings, transpositions, and phonetic variations, yet the retrieval system must operate under strict millisecond-level latency constraints. Our existing learning-to-retrieve system, the High Confidence Index (HCI), learns query-entity associations from customer behavior, relying

SIGIR 20262026Selecting which recommendation algorithm variant to advance to online experimentation is a critical decision in industry practice. Manual evaluation is subjective and time-consuming, while offline metrics such as nDCG often fail to correlate with real-world customer preferences. We present SAER, a two-stage framework (pointwise filtering and pairwise comparison) that uses Large Language Models as judges

SIGIR 20262026Recommending visually compatible products in fashion and interior design is a significant challenge, as compatibility rules are nuanced, context-dependent, and reliant on fine-grained details that traditional models fail to capture. Existing methods often struggle with heterogeneous compatibility rules (e.g., sofa-table vs. sofa-curtain) and an over-reliance on global visual features, missing critical textual

2026Deep Research (DR) systems autonomously retrieve and synthesize information from web sources, however, industrial DR applications face a critical gap: effective integration of internal tools with web search. In this work, we introduce DeepResearch Retail, an evaluation framework grounded in real-world e-commerce data for assessing Deep Research with tools (DR+Tools) in realistic commercial settings. The

npj Systems Biology and Applications2026Recent advances in Machine Learning have transformed antibody development through in-silico models, accelerating therapeutic candidate identification. However, challenges persist: rapid adaptation of property predictors to laboratory-specific assays with incomplete datasets; batch effects introducing systematic bias; assay costs necessitating efficient unseen property prediction. We introduce a novel multi-modal
