RegionReasoner: Region-Grounded Multi-Round Visual Reasoning

ICLR 2026poster

Large vision-language models have achieved remarkable progress in visual reasoning, yet most existing systems rely on single-step or text-only reasoning, limiting their ability to iteratively refine understanding across multiple visual contexts. To address this limitation, we introduce a new multi-r…

The Curse of Depth in Large Language Models

NeurIPS 2025poster

In this paper, we re-introduce the Curse of Depth, a concept that re-introduces, explains, and addresses the recent observation in modern Large Language Models (LLMs) where deeper layers are much less effective than expected. We first confirm the wide existence of this phenomenon across the most pop…

CKT-RCM: Clip-Based Knowledge Transfer and Relational Context Mining for Unbiased Panoptic Scene Graph Generation

ICASSP 2024accepted

Panoptic Scene Graph (PSG) generation aims to generate a scene graph representing pairwise relationship between objects within an image. Its use of pixel-wise segmentation mask and inclusion of background regions in relationship inference make it quickly become a popular approach. However, it has an…

IPO: Interpretable Prompt Optimization for Vision-Language Models

NeurIPS 2024poster

Pre-trained vision-language models like CLIP have remarkably adapted to various downstream tasks. Nonetheless, their performance heavily depends on the specificity of the input text prompts, which requires skillful prompt template engineering. Instead, current approaches to prompt optimization learn…

MetaModulation: Learning Variational Feature Hierarchies for Few-Shot Learning with Fewer Tasks

ICML 2023poster

Meta-learning algorithms are able to learn a new task using previously learned knowledge, but they often require a large number of meta-training tasks which may not be readily available. To address this issue, we propose a method for few-shot learning with fewer tasks, which we call MetaModulation.…
