Learning Cartesian Product Graphs with Laplacian Constraints

no code implementations12 Feb 2024 Changhao Shi, Gal Mishne

We establish statistical consistency for the penalized maximum likelihood estimation (MLE) of a Cartesian product Laplacian, and propose an efficient algorithm to solve the problem.

Graph Learning Imputation

Graph Laplacian Learning with Exponential Family Noise

no code implementations14 Jun 2023 Changhao Shi, Gal Mishne

A common challenge in applying graph machine learning methods is that the underlying graph of a system is often unknown.

Exploring Compositional Visual Generation with Latent Classifier Guidance

no code implementations25 Apr 2023 Changhao Shi, Haomiao Ni, Kai Li, Shaobo Han, Mingfu Liang, Martin Renqiang Min

We show that this paradigm based on latent classifier guidance is agnostic to pre-trained generative models, and present competitive results for both image generation and sequential manipulation of real and synthetic images.

Image Generation

Conditional Image-to-Video Generation with Latent Flow Diffusion Models

1 code implementation CVPR 2023 Haomiao Ni, Changhao Shi, Kai Li, Sharon X. Huang, Martin Renqiang Min

In this paper, we propose an approach for cI2V using novel latent flow diffusion models (LFDM) that synthesize an optical flow sequence in the latent space based on the given condition to warp the given image.

Learning Disentangled Behavior Embeddings

1 code implementation NeurIPS 2021 Changhao Shi, Sivan Schwartz, Shahar Levy, Shay Achvat, Maisan Abboud, Amir Ghanayim, Jackie Schiller, Gal Mishne

To understand the relationship between behavior and neural activity, experiments in neuroscience often include an animal performing a repeated behavior such as a motor task.

CropDefender: deep watermark which is more convenient to train and more robust against cropping

no code implementations12 Sep 2021 Jiayu Ding, Yuchen Cao, Changhao Shi

We found that the causes of vulnerability to cropping is not the loss of information on the edge, but the movement of watermark position.

Online Adversarial Purification based on Self-Supervision

no code implementations23 Jan 2021 Changhao Shi, Chester Holtz, Gal Mishne

To the best of our knowledge, our paper is the first that generalizes the idea of using self-supervised signals to perform online test-time purification.

Representation Learning

Provable Robustness by Geometric Regularization of ReLU Networks

no code implementations1 Jan 2021 Chester Holtz, Changhao Shi, Gal Mishne

Recent work has demonstrated that neural networks are vulnerable to small, adversarial perturbations of their input.

Online Adversarial Purification based on Self-supervised Learning

no code implementations ICLR 2021 Changhao Shi, Chester Holtz, Gal Mishne

Deep neural networks are known to be vulnerable to adversarial examples, where a perturbation in the input space leads to an amplified shift in the latent network representation.
