A question about terminology: we use the word "sparse" in many context, and in this case, it means that the value of a random variable is close to zero. I don't really understand why such concept can be associated with the word "sparse".

Analogy to matrices:
A sparse matrix is a matrix with many elements set to 0.
filter coding:
if you look at a single filter response channel, it will be mostly 0 with a few places that are non-zero (edges basically). The idea that the filter only fires at very few places in an image is captured by the work spareness.
