Curriculum Group Policy Optimization: Adaptive Sampling for Unleashing the Potential of Text-to-Image Generation

CVPR 2026

Text-to-Image (T2I) generation has achieved remarkable progress in recent years. Meanwhile, reinforcement learning methods, particularly those based on Group Relative Policy Optimization (GRPO), have attracted widespread attention and been successfully applied to T2I tasks. However, the uniform samp

AID: Adaptive Integration of Detectors for Safe AI with Language Models

NAACL 2025long

As Large Language Models (LLMs) increasingly influence content generation across diverse platforms, there is a heightened urgency to regulate their outputs to ensure safe usage. However, defining safety is complex, given that entities across domains may interpret it through varied lenses and develop…

Accelerating LLM Reasoning via Early Rejection with Partial Reward Modeling

EMNLP 2025

Large Language Models (LLMs) are increasingly relied upon for solving complex reasoning tasks in domains such as mathematics, logic, and multi-step question answering. A growing line of work seeks to improve reasoning quality by scaling inference time compute particularly through Process Reward Mode

Beyond Expectations: Quantile-Guided Alignment for Risk-Calibrated Language Models

NeurIPS 2025spotlight

Large language models can generate rare but catastrophic outputs, such as harmful conversations or insecure code. Existing Reinforcement Learning from Human Feedback (RLHF) typically maximizes average reward, leaving high-risk tail events insufficiently controlled. We introduce Quantile‑Guided Align…

CineTechBench: A Benchmark for Cinematographic Technique Understanding and Generation

NeurIPS 2025poster

Cinematography is a cornerstone of film production and appreciation, shaping mood, emotion, and narrative through visual elements such as camera movement, shot composition, and lighting. Despite recent progress in multimodal large language models (MLLMs) and video generation models, the capacity of…

Dehaze-RetinexGAN: Real-World Image Dehazing via Retinex-based Generative Adversarial Network

AAAI 2025technical

Deep learning based dehazing networks trained on paired synthetic data have shown impressive performance, but they struggle with significant degradation in generalization ability on real-world hazy scenes. In this paper, we propose Dehaze-RetinexGAN, a lightweight Retinex-based Generative Adversari…

MAP: Multi-Human-Value Alignment Palette

ICLR 2025oral

Ensuring that generative AI systems align with human values is essential but challenging, especially when considering multiple human values and their potential trade-offs. Since human values can be personalized and dynamically change over time, the desirable levels of value alignment vary across dif…

Probe Pruning: Accelerating LLMs through Dynamic Pruning via Model-Probing

ICLR 2025poster

We introduce Probe Pruning (PP), a novel framework for online, dynamic, structured pruning of Large Language Models (LLMs) applied in a batch-wise manner. PP leverages the insight that not all samples and tokens contribute equally to the model's output, and probing a small portion of each batch effe…

A Soft Continuum Robot With Self-Controllable Variable Curvature

RA-L 2024

This letter introduces a new type of soft continuum robot, called SCoReS, which is capable of self-controlling continuously its curvature at the segment level; in contrast to previous designs which either require external forces or machine elements, or whose variable curvature capabilities are discr

Batch Normalization Alleviates the Spectral Bias in Coordinate Networks

CVPR 2024poster

Representing signals using coordinate networks dominates the area of inverse problems recently and is widely applied in various scientific computing tasks. Still there exists an issue of spectral bias in coordinate networks limiting the capacity to learn high-frequency components. This problem is ca…

Mechanical Intelligence for Prehensile In-Hand Manipulation of Spatial Trajectories

ICRA 2023poster

The application of mechanical and other physical properties to the development of robotic systems that can easily adapt to changing external situations is known as mechanical intelligence. Following this concept, many robot hand designs can produce self-adaptive and versatile grasps with simple unde…

Assisted Learning: A Framework for Multi-Organization Learning

NeurIPS 2020spotlight

In an increasing number of AI scenarios, collaborations among different organizations or agents (e.g., human and robots, mobile units) are often essential to accomplish an organization-specific mission. However, to avoid leaking useful and possibly proprietary information, organizations typically en…
