Axonal Delay As a Short-Term Memory for Feed Forward Deep Spiking Neural Networks

no code implementations20 Apr 2022 Pengfei Sun, Longwei Zhu, Dick Botteldooren

The information of spiking neural networks (SNNs) are propagated between the adjacent biological neuron by spikes, which provides a computing paradigm with the promise of simulating the human brain.

GAMnet: Robust Feature Matching via Graph Adversarial-Matching Network

no code implementations MM 2021 Bo Jiang, Pengfei Sun, Ziyan Zhang, Jin Tang, Bin Luo

Also, GAMnet exploits sparse GM optimization as correspondence solver which is differentiable and can also incorporate discrete one-to-one matching constraints approximately in natural in the final matching prediction.

GLMNet: Graph Learning-Matching Networks for Feature Matching

no code implementations18 Nov 2019 Bo Jiang, Pengfei Sun, Jin Tang, Bin Luo

However, the matching graphs we feed to existing graph convolutional matching networks are generally fixed and independent of graph matching, which thus are not guaranteed to be optimal for the graph matching task.

Modeling neural dynamics during speech production using a state space variational autoencoder

no code implementations13 Jan 2019 Pengfei Sun, David A. Moses, Edward Chang

Characterizing the neural encoding of behavior remains a challenging task in many research areas due in part to complex and noisy spatiotemporal dynamics of evoked brain activity.

Neural networks based EEG-Speech Models

no code implementations16 Dec 2016 Pengfei Sun, Jun Qin

In this paper, we propose an end-to-end neural network (NN) based EEG-speech (NES) modeling framework, in which three network structures are developed to map imagined EEG signals to phonemes.
