A Fourier Perspective of Feature Extraction and Adversarial Robustness

IJCAI 2024poster

Adversarial robustness and interpretability are longstanding challenges of computer vision. Deep neural networks are vulnerable to adversarial perturbations that are incomprehensible and imperceptible to humans. However, the opaqueness of networks prevents one from theoretically addressing adversari…

Frequency and Scale Perspectives of Feature Extraction

ICASSP 2023accepted

Convolutional neural networks (CNNs) have achieved superior performance but still lack clarity about the nature and properties of feature extraction. In this paper, by analyzing the sensitivity of neural networks to frequencies and scales, we find that neural networks not only have low- and mediumfr…

Training Robust Spiking Neural Networks on Neuromorphic Data with Spatiotemporal Fragments

ICASSP 2023accepted

Neuromorphic vision sensors (event cameras) are inherently suitable for spiking neural networks (SNNs) and provide novel neuromorphic vision data for this biomimetic model. Due to the spatiotemporal characteristics, novel data augmentations are required to process the unconventional visual signals o…

Training Robust Spiking Neural Networks with Viewpoint Transform and Spatiotemporal Stretching

ICASSP 2023accepted

Neuromorphic vision sensors (event cameras) simulate biological visual perception systems and have the advantages of high temporal resolution, less data redundancy, low power consumption, and large dynamic range. Since both events and spikes are modeled from neural signals, event cameras are inheren…

Training Stronger Spiking Neural Networks with Biomimetic Adaptive Internal Association Neurons

ICASSP 2023accepted

As the third generation of neural networks, spiking neural networks (SNNs) are dedicated to exploring more insightful neural mechanisms to achieve near-biological intelligence. Intuitively, biomimetic mechanisms are crucial to understanding and improving SNNs. For example, the associative long-term…

Kernel Estimation Network for Blind Super-Resolution

ICASSP 2022accepted

Existing super-resolution (SR) methods commonly assume that the degradation kernels are fixed and known (e.g., bicubic downsampling or single Gaussian blurring kernel). However, these methods suffer a severe performance drop when the real degradations deviate from this assumption. To address this is…
