Biologically-Plausible Topology Improved Spiking Actor Network for Efficient Deep Reinforcement Learning

no code implementations29 Mar 2024 Duzhen Zhang, Qingyu Wang, Tielin Zhang, Bo Xu

Diverging from the conventional direct linear weighted sum, the BPT-SAN models the local nonlinearities of dendritic trees within the inter-layer connections.

Local Convolution Enhanced Global Fourier Neural Operator For Multiscale Dynamic Spaces Prediction

no code implementations21 Nov 2023 Xuanle Zhao, Yue Sun, Tielin Zhang, Bo Xu

One of the most notable methods is the Fourier Neural Operator (FNO), which is inspired by Green's function method and approximate operator kernel directly in the frequency domain.

Attention-free Spikformer: Mixing Spike Sequences with Simple Linear Transforms

no code implementations2 Aug 2023 Qingyu Wang, Duzhen Zhang, Tielin Zhang, Bo Xu

The results indicate that compared to the SOTA Spikformer with SSA, Spikformer with LT achieves higher Top-1 accuracy on neuromorphic datasets (i. e., CIFAR10-DVS and DVS128 Gesture) and comparable Top-1 accuracy on static datasets (i. e., CIFAR-10 and CIFAR-100).

Spiking Neural Network for Ultra-low-latency and High-accurate Object Detection

no code implementations21 Jun 2023 Jinye Qu, Zeyu Gao, Tielin Zhang, YanFeng Lu, Huajin Tang, Hong Qiao

We also present a SNN-based ultra-low latency and high accurate object detection model (SUHD) that achieves state-of-the-art performance on nontrivial datasets like PASCAL VOC and MS COCO, with about remarkable 750x fewer timesteps and 30% mean average precision (mAP) improvement, compared to the Spiking-YOLO on MS COCO datasets.

Mixture of personality improved Spiking actor network for efficient multi-agent cooperation

no code implementations10 May 2023 Xiyun Li, Ziyi Ni, Jingqing Ruan, Linghui Meng, Jing Shi, Tielin Zhang, Bo Xu

Inspired by this two-step psychology theory, we propose a biologically plausible mixture of personality (MoP) improved spiking actor network (SAN), whereby a determinantal point process is used to simulate the complex formation and integration of different types of personality in MoP, and dynamic and spiking neurons are incorporated into the SAN for the efficient reinforcement learning.

Here, we propose a Motif-topology improved SNN (M-SNN) for the efficient multi-sensory integration and cognitive phenomenon simulations.

Motif-topology and Reward-learning improved Spiking Neural Network for Efficient Multi-sensory Integration

1 code implementation11 Feb 2022 Shuncheng Jia, Ruichen Zuo, Tielin Zhang, Hongxing Liu, Bo Xu

Network architectures and learning principles are key in forming complex functions in artificial neural networks (ANNs) and spiking neural networks (SNNs).

Population-coding and Dynamic-neurons improved Spiking Actor Network for Reinforcement Learning

no code implementations15 Jun 2021 Duzhen Zhang, Tielin Zhang, Shuncheng Jia, Xiang Cheng, Bo Xu

Based on a hybrid learning framework, where a spike actor-network infers actions from states and a deep critic network evaluates the actor, we propose a Population-coding and Dynamic-neurons improved Spiking Actor Network (PDSAN) for efficient state representation from two different scales: input coding and neuronal coding.

Quantum Superposition Inspired Spiking Neural Network

no code implementations23 Oct 2020 Yinqian Sun, Yi Zeng, Tielin Zhang

Despite advances in artificial intelligence models, neural networks still cannot achieve human performance, partly due to differences in how information is encoded and processed compared to human brain.

1 code implementation9 Oct 2020 Tielin Zhang, Shuncheng Jia, Xiang Cheng, Bo Xu

The performance of the proposed BRP-SNN is further verified on the spatial (including MNIST and Cifar-10) and temporal (including TIDigits and DvsGesture) tasks, where the SNN using BRP has reached a similar accuracy compared to other state-of-the-art BP-based SNNs and saved 50% more computational cost than ANNs.

Finite Meta-Dynamic Neurons in Spiking Neural Networks for Spatio-temporal Learning

no code implementations7 Oct 2020 Xiang Cheng, Tielin Zhang, Shuncheng Jia, Bo Xu

Spiking Neural Networks (SNNs) have incorporated more biologically-plausible structures and learning principles, hence are playing critical roles in bridging the gap between artificial and natural neural networks.
