AI Scaling: From Up to Down and Out

no code implementations2 Feb 2025 Yunke Wang, Yanxi Li, Chang Xu

It argues that while Scaling Up of models faces inherent bottlenecks, the future trajectory of AI scaling lies in Scaling Down and Scaling Out.

Color Correction Meets Cross-Spectral Refinement: A Distribution-Aware Diffusion for Underwater Image Restoration

no code implementations8 Jan 2025 Laibin Chang, Yunke Wang, Bo Du, Chang Xu

For the sacrificed image details caused by underwater scattering, we further present the Cross-Spectral Detail Refinement (CSDR) to enhance the high-frequency details, which are integrated with the low-frequency signal as input conditions for guiding the diffusion.

FusionSAM: Latent Space driven Segment Anything Model for Multimodal Fusion and Segmentation

no code implementations26 Aug 2024 Daixun Li, Weiying Xie, Mingxiang Cao, Yunke Wang, Jiaqing Zhang, Yunsong Li, Leyuan Fang, Chang Xu

In this paper, we introduce SAM into multimodal image segmentation for the first time, proposing a novel framework that combines Latent Space Token Generation (LSTG) and Fusion Mask Prompting (FMP) modules to enhance SAM's multimodal fusion and segmentation capabilities.

Collage Prompting: Budget-Friendly Visual Recognition with GPT-4V

no code implementations18 Mar 2024 Siyu Xu, Yunke Wang, Daochang Liu, Chang Xu

Based on the observation that the accuracy of GPT-4V's image recognition varies significantly with the order of images within the collage prompt, our method further learns to optimize the arrangement of images for maximum recognition accuracy.

MAEDiff: Masked Autoencoder-enhanced Diffusion Models for Unsupervised Anomaly Detection in Brain Images

no code implementations19 Jan 2024 Rui Xu, Yunke Wang, Bo Du

To address these two issues, we propose a novel Masked Autoencoder-enhanced Diffusion Model (MAEDiff) for unsupervised anomaly detection in brain images.

Imitation Learning from Purified Demonstrations

1 code implementation11 Oct 2023 Yunke Wang, Minjing Dong, Yukun Zhao, Bo Du, Chang Xu

In the first step, we apply a forward diffusion process to smooth potential noises in imperfect demonstrations by introducing additional noise.

Unlabeled Imperfect Demonstrations in Adversarial Imitation Learning

1 code implementation13 Feb 2023 Yunke Wang, Bo Du, Chang Xu

The trajectories of an initial agent policy could be closer to those non-optimal expert demonstrations, but within the framework of adversarial imitation learning, agent policy will be optimized to cheat the discriminator and produce trajectories that are similar to those optimal expert demonstrations.

Multi-Tailed Vision Transformer for Efficient Inference

no code implementations3 Mar 2022 Yunke Wang, Bo Du, Wenyuan Wang, Chang Xu

To satisfy the sequential input of Transformer, the tail of ViT first splits each image into a sequence of visual tokens with a fixed length.
