Classification: CPC G  H | IPC G  H

Claim 14:
15. A non-transitory computer-readable storage medium encoded with a computer program including instructions for a method comprising:
referring to dimension setting information, which is information representing an attribute for each of data dimensions of a multidimensional dataset; and
generating a compressor based on the information representing the attribute for each of the data dimensions represented by the dimension setting information; and
compressing a write target multidimensional dataset using the generated compressor and writing compressed data in a storage apparatus,
wherein the attribute for each of the data dimensions is continuation, such that values belonging to the dimension are continuous values, or discrete, such that the values belonging to a dimension are discrete values,
wherein the compressor includes a processing unit,
wherein the processing unit includes, among an encoder that encodes an input dataset, a decoder that decodes a dataset based on a feature value map generated by quantizing data output from the encoder, and an entropy estimator that estimates entropy based on the feature value map, at least the entropy estimator, and
wherein the compressor generation processing includes configuring the processing unit based on the attribute for each of the data dimensions represented by the dimension setting information.
