Claim 2:
3. The storage system according to claim 2, wherein
the compression operation is a lossy compression operation, and
when teacher data is input, for each of a plurality of pieces of teacher data and for each of the plurality of compression routes, the processor
acquires the teacher data, and decoded teacher data that is data acquired by decompressing encoded teacher data acquired by compressing the teacher data in the compression route,
calculates an error between each of the plurality of pieces of teacher data and each of the plurality of pieces of decoded teacher data, and
learns selection of a compression route based on the error calculated for each of the plurality of pieces of decoded teacher data, and the compression operation scale of each of the plurality of compression routes.
