How does the two-part input of the loop body a handle? According to Figure 5, the $X _t$ and $h _{t-1}$ are directly spliced together to become a larger matrix/vector $[x_t, h_{t-1}]$. Assuming that the shapes of the $X _t$ and $h _{t-1}$ are [1, 3] and [1, 4] respectively, the shape of the input vectors of the full join layer in the last

Published in 2015 This "Fully convolutional Networks for Semantic segmentation" is important in the field of image semantic segmentation.1 CNN and FCNTypically, the CNN network is connected to a number of full-join layers after the convolutional layer, mapping the feature map generated by the convolution layer (feature map) to a fixed-length eigenvector.

Deep Learning SpecializationWunda recently launched a series of courses on deep learning in Coursera with Deeplearning.ai, which is more practical compared to the previous machine learning course. The operating language also has MATLAB changed to Python to be more fit to the current trend. A study note on this series of courses will be made here.The deep learning specialization is divided into five courses, namely:

CNN's current applications are not limited to images and videos, but can also be used for time series

in the first convolutional layer and the first fully connected layer. Finally, they reduced the number of first convolutional neurons from 20 to 10, reducing the number of neurons in the first fully-connected layer from 500 to 100. After 2000 iterations, the network accuracy rate reached 98.2%.Figure 9 Mnist network analysis diagram. From left to right, the first convolution layer, the second

OverviewAlthough the CNN deep convolution network in the field of image recognition has achieved significant results, but so far people to why CNN can achieve such a good effect is unable to explain, and can not put forward an effective network promotion strategy. Using the method of Deconvolution visualization in this paper, the author discovers some problems of alexnet, and makes some improvements on the basis of alexnet, so that the network achieves better results than alexnet. At the same ti
