). This convolution core, such as the 3x3 convolution core, has 9 numbers, and these 9 numbers are taken in this space to calculate a convolution, averaging a second shot to another space, also counted as a convolution. The convolution cores in these convolution are the same. So from the very beginning, the MLP went down to CNN and defined the concept of a convolution. That's the difference between the two points.
First, the next node is the second-l
1. Recurrent neural Network (RNN)
Although the expansion from the multilayer perceptron (MLP) to the cyclic Neural network (RNN) seems trivial, it has far-reaching implications for sequence learning. The use of cyclic neural networks (RNN) is used to process sequence data. In the traditional neural network model, the layer and layer are all connected, and the nodes between each layer are not connected. But this common neural network is powerless for
downloaded from the Internet, named: mnist.pkl.gz handwriting Font library, contains three parts of the data, training data set train_set:50000 training samples, validation set Valid_set, We can read the data with the following code and then use plot to display one of the images:
In the above code, I show the 8th picture, you can see the following results:
The eighth sample is the number 1.
2, LeNet-5 realization
First you need to know mnist.pkl.gz this library to our image size is 28*28, s
neural network can approximate almost all functions. However, if the activation function is an identity activation function (i.e. f (x) =x), this property is not satisfied, and if MLP is using an identity activation function, then the entire network is equivalent to a single-layer neural network. Micro-Usability: This property is necessary when the optimization method is based on the gradient. Monotonicity: When the activation function is monotonous,
