input neurons on the original. Because these neurons want the same feature, they are filtered by the same filter. Therefore, the parameters of this 10x10 connection on each neuron are a hair-like one. Does it make sense? In fact, this 10x10 parameter is shared by all neurons on this feature map. This is the weight sharing Ah! So even if you have 6 feature graphs, only 6x10x10 = 600 parameters that need to be trained. (assuming that the input layer has only one picture)Further, this 10x10 parame

However, it is inconvenient to directly use the Threading class. For this reason, Parallel computing classes such as Parallel are added in several later versions of C #.
