Evaluation apparatus, evaluation method and program

An evaluation method executed by an evaluation device for evaluating a plurality of dimensionality reduction schemes, the evaluation method comprising:

• extracting a first feature of a data set before dimensionality reduction and a second feature of a data set after dimensionality reduction from the data set before dimensionality reduction and the data set after dimensionality reduction for each of the plurality of dimensionality reduction schemes using a plurality of feature extraction algorithms;
• calculating a similarity between the first feature and the second feature using a plurality of feature similarity calculation algorithms corresponding to the plurality of feature extraction algorithms;
• and
• outputting the similarity calculated for each of the plurality of dimensionality reduction schemes.

A non-transitory computer readable medium storing one or more instructions causing a computer to execute:

• evaluating a plurality of dimensionality reduction schemes, wherein evaluating the plurality of dimensionality reduction schemes comprises:
• extracting a first feature of a data set before dimensionality reduction and a second feature of a data set after dimensionality reduction from the data set before dimensionality reduction and the data set after dimensionality reduction for each of the plurality of dimensionality reduction schemes using a plurality of feature extraction algorithms;
• calculating a similarity between the first feature and the second feature using a plurality of feature similarity calculation algorithms corresponding to the plurality of feature extraction algorithms;
• and
• outputting the similarity calculated for each of the plurality of dimensionality reduction schemes.
