The calculation of the sensing field in CNN

The receptive field is a kind of thing, from the angle of CNN visualization, is the output featuremap a node response to the input image of the area is to feel wild.For example, if our first layer is a 3*3 core, then each node in the Featuremap that we get through this convolution is derived from this 3*3 convolution core and the 3*3 region of the original image, then we call this Featuremap node to feel the wild size 3*3If you go through the pooling layer, assuming that the

Summary of pooling methods (Pooling)

two adjacent pooled windows as stride. General pooling because each pooled window is not duplicated, sizex=stride.The most common pooled operations are the average pooled mean pooling and Max pooled Max pooling:Average pooling: Calculates the average of an image area as a pooled value for that region.Average pooling: The maximum value of the selected image area as the value after the zone is pooled.2.

Lossless JBIG2 encoding library (Lossless JBIG2 Encoder)

After the code is compiled, the EXE file is output to encode the data provided by the existing bitmap file or StdIn, And the DLL library called by other applications is not provided. To add the JBIG2 encoding function to the PDF patch Ding, I modified the Code to remove the lossy compression function and the dependency between the Leptonica

Research on the memory model of Swift object (i.)

memory alignment. Many computer systems impose restrictions on the legal address of a basic data type, requiring that the address of a data type object must be a multiple of a value K(usually 2, 4, or 8). This alignment restriction simplifies the hardware design that forms the interface between the processor and the memory system. The alignment principle is that the address of any K-byte base object must be a multiple of k. Memorylayout\ represents the memory alignment principle for data type T

Can we be more aggresive on this?! Yes we can use stride! Basically stride is while moving kernel across input, it skips certain input by certain length.We can easily tell how

Some points near the saddle point have a greater cost than the saddle point, while others have a smaller cost. 6, PCA (principal component analysis) is to extract the data distribution variance ratio of the larger direction, also play the role of dimensionality reduction. In the neural network, if the hidden reservoir can realize dimensionality reduction, it extracts the characteristic of predictive ability. 7, CNN and RNN will share
