深度可分离卷积(depthwise separable convolutions) 深度可分离卷积depthwise separable convolution是由depthwise(DW)和pointwise(PW)两个部分结合起来,用来提取特征feature map。 需要注意的是,深度可分离卷积和正常(标准)卷积是等效的。 废话不多说,直接上个图。 图中(a)表示的是标准卷积,假设输入特征图尺寸为,卷积核...
改进后的加入空洞卷积 (dilated convolutions) 的因果神经网络 可以看到,在通过空洞卷积扩张后,因果神经网络中下一层神经元对上一次神经元的历史数据感受视野大大扩展,这也提升了因果卷积网络对需要较长记忆的时间序列推测任务的建模能力。具体的,对于采用大小为 k 的卷积核,对于输入为 \bm{x} 的空洞卷积 (dilated...
This chapter introduces the basic ideas of causal convolutions and convolution equations. The main tool is the Laplace transform, which we briefly introduce. The concepts are described by a collection of examples of increasing difficulty culminating in the single layer potential representation of the ...
因果卷积(causal Convolutions)和扩展卷积(Dilated Convolutions) 背景 对于序列问题(Sequence Modeling)的处理方法,通常采用RNN或者LSTM,例如处理一段视频/音频,往往会沿着时间方向(时序)进行操作。通常CNN网络都被认为适合处理图像数据而不适合处理sequence modeling问题;而今年来,由于RNN及LSTM这类模型的瓶颈,越来越多的...
The distinguishing characteristics of the proposed model is that the convolutions in the model architecture are causal, where an output at a certain time step is convolved only with elements from the same or earlier time steps in the previous layer. Accordingly, no information leakage is induced ...

In the image above, if the lower layer had a stride of 2, we would skip (2,3,4,5) and this would have given us the same results. reference: Causal padding in keras Convolutions in Autoregressive Neural Networks

DCC can be divided into two parts: dilated convolution [31] and causal convolution [32]. Causal convolution can solve the problem of different input and output time steps in the CNNs model and future information leakage. Dilated convolution can widen the receptive field of the convolution kernel...
In this paradigm, the bottleneck is the extent to which the RNN can model long-range dependencies, and the most successful approaches rely on causal convolutions, which offer better access to earlier parts of the sequence than ... X Chen,N Mishra,M Rohaninejad,... 被引量: 14发表: 2017...
