CLIPoint3D: Language-Grounded Few-Shot Unsupervised 3D Point Cloud Domain Adaptation

Mainak Singha, Sarthak Mehrotra, Paolo Casari +3

Recent vision-language models (VLMs) such as CLIP demonstrate impressive cross-modal reasoning, extending beyond images to 3D perception. Yet, these models remain fragile under dom…

FedMVP: Federated Multimodal Visual Prompt Tuning for Vision-Language Models

Mainak Singha, Subhankar Roy, Sarthak Mehrotra +4

In federated learning, textual prompt tuning adapts Vision-Language Models (e.g., CLIP) by tuning lightweight input tokens (or prompts) on local client data, while keeping network…

When Domain Generalization meets Generalized Category Discovery: An Adaptive Task-Arithmetic Driven Approach

Vaibhav Rathore, Shubhranil B, Saikat Dutta +3

Generalized Class Discovery (GCD) clusters base and novel classes in a target domain using supervision from a source domain with only base classes. Current methods often falter wit…
