2026Humans effortlessly locate and identify objects by touch alone, even without vision. In contrast, robotic systems rely heavily on vision and struggle with autonomous tactile exploration and object identification. We present TACTFUL, a vision-free tactile exploration framework that enables a multi-fingered robot to autonomously explore confined workspaces, discover objects through contact, and identify them

RecSys 2026 Workshop for Agentic and Generative AI for E-commerce2026Large-language-model (LLM) agents increasingly operate and evaluate e-commerce workflows, and a recurring building block is a skill router : a semantic-retrieval layer that maps a free-form question to the correct skill in a catalog. The same layer lets an LLM-as-judge evaluator decide which skill should have answered and whether the catalog covers the question at all. In practice it runs on general-purpose

RecSys 2026 Workshop for Agentic and Generative AI for E-commerce2026Training classifiers for e-commerce catalog management is bottlenecked by two simultaneous scarcities: underspecified task specifications (a bare URL or one-sentence description) and few or no labeled examples. We present MASLOW, to our knowledge the first multi-agent synthetic data pipeline that handles the full journey from underspecified inputs to labeled training data without requiring clean class labels

2026Large language models increasingly need to generate structured outputs that conform to predefined schemas, with one common constraint being selection from a finite set of valid strings. Current constrained decoding systems handle this through general-purpose grammar compilation, which becomes prohibitively slow as the number of valid values grows into the thousands, a cardinality wall. We introduce the

2026Domain-specific finetuning is essential for dense retrievers, yet not all data pairs contribute equally to the learning process. We introduce OPERA1 , a data pruning framework that exploits this heterogeneity to improve both the effectiveness and efficiency of retrieval model adaptation. We first investigate static pruning (SP), which retains only high-similarity query document pairs, revealing an intrinsic
