Inversion-by-Inversion: Exemplar-based Sketch-to-Photo Synthesis via Stochastic Differential Equations without Training

1 code implementation15 Aug 2023 XiMing Xing, Chuang Wang, Haitao Zhou, Zhihao Hu, Chongxuan Li, Dong Xu, Qian Yu

In the full-control inversion process, we propose an appearance-energy function to control the color and texture of the final generated photo. Importantly, our Inversion-by-Inversion pipeline is training-free and can accept different types of exemplars for color and texture control.

Class Incremental Learning with Self-Supervised Pre-Training and Prototype Learning

no code implementations4 Aug 2023 Wenzhuo LIU, Xinjian Wu, Fei Zhu, Mingming Yu, Chuang Wang, Cheng-Lin Liu

This is hard for DNN because it tends to focus on fitting to new classes while ignoring old classes, a phenomenon known as catastrophic forgetting.

DiffSketcher: Text Guided Vector Sketch Synthesis through Latent Diffusion Models

1 code implementation NeurIPS 2023 XiMing Xing, Chuang Wang, Haitao Zhou, Jing Zhang, Qian Yu, Dong Xu

Even though trained mainly on images, we discover that pretrained diffusion models show impressive power in guiding sketch synthesis.

Proxy Graph Matching with Proximal Matching Networks

no code implementations AAAI 2021 Haoru Tan, Chuang Wang, Sitong Wu, Tie-Qiang Wang, Xu-Yao Zhang, Cheng-Lin Liu

It consists of three parts: a graph neural network to generate a high-level local feature, an attention-based module to normalize the rotational transform, and a global feature matching module based on proximal optimization.

Subspace Estimation from Incomplete Observations: A High-Dimensional Analysis

no code implementations17 May 2018 Chuang Wang, Yonina C. Eldar, Yue M. Lu

In addition to providing asymptotically exact predictions of the dynamic performance of the algorithms, our high-dimensional analysis yields several insights, including an asymptotic equivalence between Oja's method and GROUSE, and a precise scaling relationship linking the amount of missing data to the signal-to-noise ratio.

In addition to characterizing the dynamic performance of online learning algorithms, our asymptotic analysis also provides useful insights.

The Scaling Limit of High-Dimensional Online Independent Component Analysis

no code implementations NeurIPS 2017 Chuang Wang, Yue M. Lu

As the ambient dimension tends to infinity, and with proper time scaling, we show that the time-varying joint empirical measure of the target feature vector and the estimates provided by the algorithm will converge weakly to a deterministic measured-valued process that can be characterized as the unique solution of a nonlinear PDE.
