Assignee: HITACHI, LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A storage system comprising:
a storage apparatus;
a memory; and
a processor that controls data input and output, wherein
the memory stores dimension setting information, which is information representing an attribute for each of data dimensions of a multidimensional dataset,
the processor performs compressor generation processing, which is processing for generating a compressor based on the dimension setting information,
the processor performs write processing,
the write processing is processing for compressing a write target multidimensional dataset using the generated compressor and writing compressed data in the storage apparatus,
the attribute for each of the data dimensions is continuation, such that values belonging to a dimension are continuous values, or discrete, such that the values belonging to the dimension are discrete values,
the compressor includes a processing unit,
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
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.
