Kernel-Based Steering of CLIP with Vision-Language Model Preferences

Sajjad Ghiasvand, Haniyeh Ehsani Oskouie, Sina Mansouri +3

Large vision-language models (VLMs) can judge visual similarity, but their judgments are not directly available as compact image embeddings for efficient comparison. We study how t…

Low-Rank Prompt Learning for Vision-Language Models with Fixed-Token Bases

Tanvir Muntakim Tonoy, Sajjad Ghiasvand, Mahnoosh Alizadeh +1

Prompt learning adapts CLIP to downstream recognition by replacing hand-written templates with learned continuous context vectors, which in Context Optimization (CoOp) form a dense…

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

Sajjad Ghiasvand, Yifan Yang, Mahnoosh Alizadeh +1

Prompt tuning adapts vision--language models with few trainable parameters, but computing their gradients still requires backpropagation through frozen encoders. We introduce ZOMP,…

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): it has no single correct answer, and most aesthetic evaluation measures models against nu…

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…

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…

Communication-Efficient and Tensorized Federated Fine-Tuning of Large Language Models

Sajjad Ghiasvand, Yifan Yang, Zhiyu Xue +3

Parameter-efficient fine-tuning (PEFT) methods typically assume that Large Language Models (LLMs) are trained on data from a single device or client. However, real-world scenarios…
