Zusammenfassung:A learning device according to an embodiment includes an acquirer, an extractor, a plurality of processors, and an identifier. The acquirer is configured to acquire a paper sheet image which is a captured image of a paper sheet. The extractor is configured to extract a plurality of primary feature images having different objects to be recognized from the paper sheet image acquired by the acquirer. The plurality of processors are configured to perform respective convolution and pooling processes on the plurality of primary feature images extracted by the extractor to generate a plurality of secondary feature images having different objects to be recognized. The identifier is configured to sequentially update and learn a parameter set for identifying a sheet type of the paper sheet on the basis of a result of a combination process on each of the plurality of secondary feature images generated by the plurality of processors.
