Don’t Think Longer, Think Wisely: Optimizing Thinking Dynamics for Large Reasoning Models

NeurIPS 2025poster

While recent success of large reasoning models (LRMs) significantly advanced LLMs' reasoning capability by optimizing the final answer accuracy using reinforcement learning, they may also drastically increase the output length due to *overthinking*—characterized by unnecessarily complex reasoning pa…

Unlabeled Data Improves Fine-Grained Image Zero-shot Classification with Multimodal LLMs

NeurIPS 2025poster

Despite Multimodal Large Language Models (MLLMs) showing promising results on general zero-shot image classification tasks, fine-grained image classification remains challenging. It demands precise attention to subtle visual details to distinguish between visually similar subcategories—details that…

DiffusionNAG: Predictor-guided Neural Architecture Generation with Diffusion Models

ICLR 2024poster

Existing NAS methods suffer from either an excessive amount of time for repetitive sampling and training of many task-irrelevant architectures. To tackle such limitations of existing NAS methods, we propose a paradigm shift from NAS to a novel conditional Neural Architecture Generation (NAG) framewo…

One Prompt is not Enough: Automated Construction of a Mixture-of-Expert Prompts

ICML 2024poster

Large Language Models (LLMs) exhibit strong generalization capabilities to novel tasks when prompted with language instructions and in-context demos. Since this ability sensitively depends on the quality of prompts, various methods have been explored to automate the instruction design. While these m…

Meta-prediction Model for Distillation-Aware NAS on Unseen Datasets

ICLR 2023top-25%

Distillation-aware Neural Architecture Search (DaNAS) aims to search for an optimal student architecture that obtains the best performance and/or efficiency when distilling the knowledge from a given teacher model. Previous DaNAS methods have mostly tackled the search for the neural architecture for…
