The autoencoder of Sparse Coding explains:
First, let's take a look at the LK norm number of vector X. Its value is: From this we can see that the l1 norm is the sum of each element, and the L2 norm is the Euclidean distance from the vector to the far point.
The price function for expressing Sparse Coding in the form of a matrix is as follows:
As mentioned above, the base value S is also subjected to sparse penalty, which is constrained by L1
