Beyond Semantic Similarity: Performance and Costs of Agentic Retrieval for Complex Tasks

Reza Esfandiarpoor, Radek Osmulski, Yauhen Babakhin +8

Modern information systems, including many agentic workflows, use dense retrieval to explore large amounts of unstructured data. However, dense retrieval relies on surface-level se…

If CLIP Could Talk: Understanding Vision-Language Model Representations Through Their Preferred Concept Descriptions

Reza Esfandiarpoor, Cristina Menghini, Stephen H. Bach

Recent works often assume that Vision-Language Model (VLM) representations are based on visual attributes like shape. However, it is unclear to what extent VLMs prioritize this inf…

Follow-Up Differential Descriptions: Language Models Resolve Ambiguities for Image Classification

Reza Esfandiarpoor, Stephen H. Bach

A promising approach for improving the performance of vision-language models like CLIP for image classification is to extend the class descriptions (i.e., prompts) with related att…

An Adaptive Method for Weak Supervision with Drifting Data

Alessio Mazzetto, Reza Esfandiarpoor, Akash Singirikonda +2

We introduce an adaptive method with formal quality guarantees for weak supervision in a non-stationary setting. Our goal is to infer the unknown labels of a sequence of data by us…
