DiffHarmony: Latent Diffusion Model Meets Image Harmonization

no code implementations9 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.

Synthesizing Knowledge-enhanced Features for Real-world Zero-shot Food Detection

1 code implementation14 Feb 2024 Pengfei Zhou, Weiqing Min, Jiajun Song, Yang Zhang, Shuqiang Jiang

The complexity of food semantic attributes further makes it more difficult for current ZSD methods to distinguish various food categories.

CMMU: A Benchmark for Chinese Multi-modal Multi-type Question Understanding and Reasoning

no code implementations25 Jan 2024 Zheqi He, Xinya Wu, Pengfei Zhou, Richeng Xuan, Guang Liu, Xi Yang, Qiannan Zhu, Hua Huang

Current multi-modal benchmarks for domain-specific knowledge concentrate on multiple-choice questions and are predominantly available in English, which imposes limitations on the comprehensiveness of the evaluation.

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.

Phase transitions and optimal algorithms for semi-supervised classifications on graphs: from belief propagation to graph convolution network

no code implementations1 Nov 2019 Pengfei Zhou, Tianyi Li, Pan Zhang

For the first time, well-controlled benchmark datasets with asymptotially exact properties and optimal solutions could be produced for the evaluation of graph convolution neural networks, and for the theoretical understanding of their strengths and weaknesses.
