Drawbacks of Spiking ResNet 1.Spiking ResNet并不适用于所有神经元模型来实现identity mapping。 如果添加网络层实现了identity mapping,深度模型的训练误差不会大于浅层模型。但是最初单纯地增加层数无法实现这一要求,直到residual learning的提出。下面是三种不同的残差块(包括本文提出的SEW)
我们的网络由一组残差模块构成,这些模块具有相同的拓扑结构topology。 受VGG/ResNets启发, 遵循两个简单的原则: 1)if producing spatial maps of the same size, the blocks share the same hyper-parameters (width and filter sizes) 如果输出的空间尺寸一样,那么模块的超参数(宽度和滤波器尺寸)也是一样的。 2...
Communication by rare, binary spikes is a key factor for the energy efficiency of biological brains. However, it is harder to train biologically-inspired spiking neural networks than artificial neural networks. This is puzzling given that theoretical res
这再次表明cardinality比深度和宽度维度更有效。 Residual connections. 下表显示了残差(shortcut)连接的效果: 从ResNeXt-50删除shortcuts会使错误增加3.9个百分点,达到26.1%。而从ResNet-50中删除shortcuts则要糟糕得多(31.2%)。这些比较表明残差连接有助于优化,而聚合转换是更强的表示,这一点可以从以下事实看出:它们...

2.1 Learning Methods of Spiking Neural Networks ANN到SNN的转换(ANN2SNN)[20, 4, 46, 49, 12, 11, 6, 54, 33]和具有替代梯度的反向传播[40]是获得深度SNN的两种主要方法。ANN2SNN方法首先用ReLU激活训练ANN,然后通过用脉冲神经元替换ReLU并添加缩放操作(如权重归一化和阈值平衡)将ANN转换为SNN。最近的一...
deep residual shrinkage networks integrate a few specialized neural networks as trainable modules to automatically determine the thresholds, so that professional expertise on signal processing is not required. The efficacy of the developed methods is validated through experiments with various types of noise...
The CAMP-BD model is a combination of a CNN and a RNN and it was used in [155] to predict distortion within laser-based addictive manufacturing tolerance limits by considering the local heat transfer for point-wise distortion prediction. CAMP-DB has two advantages. First it leverages large ...
