Certified Defense via Latent Space Randomized Smoothing with Orthogonal Encoders

no code implementations1 Aug 2021 Huimin Zeng, Jiahao Su, Furong Huang

Randomized Smoothing (RS), being one of few provable defenses, has been showing great effectiveness and scalability in terms of defending against $\ell_2$-norm adversarial perturbations.

Scaling-up Diverse Orthogonal Convolutional Networks with a Paraunitary Framework

no code implementations16 Jun 2021 Jiahao Su, Wonmin Byeon, Furong Huang

To address this problem, we propose a theoretical framework for orthogonal convolutional layers, which establishes the equivalence between various orthogonal convolutional layers in the spatial domain and the paraunitary systems in the spectral domain.

Convolutional Tensor-Train LSTM for Spatio-temporal Learning

2 code implementations NeurIPS 2020 Jiahao Su, Wonmin Byeon, Jean Kossaifi, Furong Huang, Jan Kautz, Animashree Anandkumar

Learning from spatio-temporal data has numerous applications such as human-behavior analysis, object tracking, video compression, and physics simulation. However, existing methods still perform poorly on challenging video tasks such as long-term forecasting.

ARMA Nets: Expanding Receptive Field for Dense Prediction

no code implementations NeurIPS 2020 Jiahao Su, Shiqi Wang, Furong Huang

In this work, we propose to replace any traditional convolutional layer with an autoregressive moving-average (ARMA) layer, a novel module with an adjustable receptive field controlled by the learnable autoregressive coefficients.

Convolutional Tensor-Train LSTM for Long-Term Video Prediction

no code implementations25 Sep 2019 Jiahao Su, Wonmin Byeon, Furong Huang, Jan Kautz, Animashree Anandkumar

Long-term video prediction is highly challenging since it entails simultaneously capturing spatial and temporal information across a long range of image frames. Standard recurrent models are ineffective since they are prone to error propagation and cannot effectively capture higher-order correlations.

Tensorial Neural Networks: Generalization of Neural Networks and Application to Model Compression

no code implementations25 May 2018 Jiahao Su, Jingling Li, Bobby Bhattacharjee, Furong Huang

We propose tensorial neural networks (TNNs), a generalization of existing neural networks by extending tensor operations on low order operands to those on high order ones.
