CTR-LORA: CURVATURE-AWARE AND TRUST-REGION GUIDED LOW-RANK ADAPTATION FOR LARGE LANGUAGE MODELS

ICASSP 2026oral

Parameter-efficient fine-tuning (PEFT) has become the standard approach for adapting large language models under limited compute and memory budgets. Although previous methods improve efficiency through low-rank updates, quantization, or heuristic budget reallocation, they often decouple the allocati…

Prime Once, then Reprogram Locally: An Efficient Alternative to Black-Box Service Model Adaptation

CVPR 2026

Adapting closed-box service models (i.e., APIs) for target tasks typically relies on reprogramming via Zeroth-Order Optimization (ZOO). However, this standard strategy is known for extensive, costly API calls and often suffers from slow, unstable optimization. Furthermore, we observe that this parad

Seeing Clearly, Reasoning Confidently: Plug-and-Play Remedies for Vision Language Model Blindness

CVPR 2026

Vision language models (VLMs) have achieved remarkable success in broad visual understanding, yet they remain challenged by object-centric reasoning on rare objects due to the scarcity of such instances in pretraining data. While prior efforts alleviate this issue by retrieving additional data or in

DPCore: Dynamic Prompt Coreset for Continual Test-Time Adaptation

ICML 2025poster

Continual Test-Time Adaptation (CTTA) seeks to adapt source pre-trained models to continually changing, unseen target domains. While existing CTTA methods assume structured domain changes with uniform durations, real-world environments often exhibit dynamic patterns where domains recur with varying…

Doctor Approved: Generating Medically Accurate Skin Disease Images through AI-Expert Feedback

NeurIPS 2025poster

Paucity of medical data severely limits the generalizability of diagnostic ML models, as the full spectrum of disease variability can not be represented by a small clinical dataset. To address this, diffusion models (DMs) have been considered as a promising avenue for synthetic image generation and…

Understanding the Transferability of Representations via Task-Relatedness

NeurIPS 2024poster

The growing popularity of transfer learning due to the availability of models pre-trained on vast amounts of data, makes it imperative to understand when the knowledge of these pre-trained models can be transferred to obtain high-performing models on downstream target tasks. However, the exact condi…
