ZOMP: Zeroth-Order Multi-Modal Prompt Tuning for Vision-Language Models

Sajjad Ghiasvand, Yifan Yang, Mahnoosh Alizadeh +1

Fine-tuning vision-language models such as CLIP typically requires backpropagation (BP) through the full model, which is infeasible when only forward-pass access is available, as i…

REALM: Reliable Expertise-Aware Language Model Fine-Tuning from Noisy Annotations

Sajjad Ghiasvand, Mark Beliaev, Mahnoosh Alizadeh +1

Supervised fine-tuning of large language models relies on human-annotated data, yet annotation pipelines routinely involve multiple crowdworkers of heterogeneous expertise. Standar…

MMLoP: Multi-Modal Low-Rank Prompting for Efficient Vision-Language Adaptation

Sajjad Ghiasvand, Haniyeh Ehsani Oskouie, Mahnoosh Alizadeh +1

Prompt learning has become a dominant paradigm for adapting vision-language models (VLMs) such as CLIP to downstream tasks without modifying pretrained weights. While extending pro…

Can MLLMs Critique Like Humans? Evaluating Open-Ended Aesthetic Reasoning in Multimodal Large Language Models

Sajjad Ghiasvand, Maryam Amirizaniani, Haniyeh Ehsani Oskouie +2

Open-ended aesthetic critique is a challenge for multimodal large language models (MLLMs): unlike multiple-choice aesthetic benchmarks, it has no single correct answer, and most ae…

Steady-state Based Approach to Online Non-stochastic Control

Vijeth Hebbar, Spencer Hutchinson, Mahnoosh Alizadeh +1

We study the problem of online non-stochastic control (ONC), which is the control of a linear system under adversarial disturbances and adversarial cost functions, with the aim of…

pFedMMA: Personalized Federated Fine-Tuning with Multi-Modal Adapter for Vision-Language Models

Sajjad Ghiasvand, Mahnoosh Alizadeh, Ramtin Pedarsani

Vision-Language Models (VLMs) like CLIP have demonstrated remarkable generalization in zero- and few-shot settings, but adapting them efficiently to decentralized, heterogeneous da…
