Claim 9:
10. The storage system according to claim 9, wherein
the compression operation is a lossy compression operation,
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 a plurality of pieces of decoded teacher data acquired by decompressing encoded teacher data, acquired by compressing the teacher data in the compression route, in the plurality of decompression routes,
calculates an error between the teacher data and each of the plurality of pieces of decoded teacher data acquired for the teacher data, and
learns selection of a route combination based on the error calculated for each of the plurality of pieces of decoded teacher data, and compression operation scales and decompression operation scales of a plurality of route combinations, and

each of the plurality of route combinations is a combination of any compression route and any decompression route.
