EnerVerse: Envisioning Embodied Future Space for Robotics Manipulation

no code implementations3 Jan 2025 Siyuan Huang, Liliang Chen, Pengfei Zhou, Shengcong Chen, Zhengkai Jiang, Yue Hu, Peng Gao, Hongsheng Li, Maoqing Yao, Guanghui Ren

We introduce EnerVerse, a comprehensive framework for embodied future space generation specifically designed for robotic manipulation tasks.

DIETS: Diabetic Insulin Management System in Everyday Life

no code implementations19 Nov 2024 Hanyu Zeng, Hui Ji, Pengfei Zhou

People with diabetes need insulin delivery to effectively manage their blood glucose levels, especially after meals, because their bodies either do not produce enough insulin or cannot fully utilize it.

Large Language Model Management

Language-centered Human Activity Recognition

no code implementations12 Sep 2024 Hua Yan, Heng Tan, Yi Ding, Pengfei Zhou, Vinod Namboodiri, Yu Yang

To address this, we propose LanHAR, a novel system that leverages Large Language Models (LLMs) to generate semantic interpretations of sensor readings and activity labels for cross-dataset HAR.

Invisible Optical Adversarial Stripes on Traffic Sign against Autonomous Vehicles

no code implementations10 Jul 2024 Dongfang Guo, Yuting Wu, Yimin Dai, Pengfei Zhou, Xin Lou, Rui Tan

This paper presents an attack that uses light-emitting diodes and exploits the camera's rolling shutter effect to create adversarial stripes in the captured images to mislead traffic sign recognition.

Unleashing the Power of Unlabeled Data: A Self-supervised Learning Framework for Cyber Attack Detection in Smart Grids

no code implementations22 May 2024 Hanyu Zeng, Pengfei Zhou, Xin Lou, Zhen Wei Ng, David K. Y. Yau, Marianne Winslett

Different from existing approaches, the proposed framework does not rely on large amounts of well-curated labeled data but makes use of the massive unlabeled data in the wild which are easily accessible.

DiffHarmony: Latent Diffusion Model Meets Image Harmonization

1 code implementation9 Apr 2024 Pengfei Zhou, Fangxiang Feng, Xiaojie Wang

To deal with these issues, in this paper, we first adapt a pre-trained latent diffusion model to the image harmonization task to generate the harmonious but potentially blurry initial images.

ISDA: Position-Aware Instance Segmentation with Deformable Attention

1 code implementation23 Feb 2022 Kaining Ying, Zhenhua Wang, Cong Bai, Pengfei Zhou

Most instance segmentation models are not end-to-end trainable due to either the incorporation of proposal estimation (RPN) as a pre-processing or non-maximum suppression (NMS) as a post-processing.

Boltzmann machines as two-dimensional tensor networks

no code implementations10 May 2021 Sujie Li, Feng Pan, Pengfei Zhou, Pan Zhang

Using numerical experiments, we demonstrate that the proposed algorithm is much more accurate than the state-of-the-art machine learning methods in estimating the partition function of restricted Boltzmann machines and deep Boltzmann machines, and have potential applications in training deep Boltzmann machines for general machine learning tasks.
