What does pooling mean?
Pooling is used for downsampling(降采样). For example, "max pooling" means using the max element of a n*m matrix such as 3*3 matrix. "Min pooling" and "average pooling" mean using the min and the average element of the matrix, respectively. The aforementioned example is used for a plane and it can also used for a cube.
A 30*30 matrix can be divided into 9 10*10 matrixes. Is it meaningful to use pooling for the 9 small matrixs? Maybe it is meaningless since pooling is always used for each small block(块与块之间的pooling也许没意义).
