Abstract: Learning method includes performing a first process in which a coarse class classifier configured with a first neural network is made to classify a plurality of images given as a set of images each attached with a label indicating a detailed class into a plurality of coarse classes including a plurality of detailed classes and is then made to learn a first feature that is a feature common in each of the coarse classes, and performing a second process in which a detailed class classifier, configured with a second neural network that is the same in terms of layers other than the final layer as but different in terms of the final layer from the first neural network made to perform the learning in the first process, is made to classify the set of images into detailed classes and learn a second feature of each detailed class.

Abstract: An image recognition method includes: receiving an image; acquiring processing result information including values of processing results of convolution processing at positions of a plurality of pixels that constitute the image by performing the convolution processing on the image by using different convolution filters; determining 1 feature for each of the positions of the plurality of pixels on the basis of the values of the processing results of the convolution processing at the positions of the plurality of pixels included in the processing result information and outputting the determined feature for each of the positions of the plurality of pixels; performing recognition processing on the basis of the determined feature for each of the positions of the plurality of pixels; and outputting recognition processing result information obtained by performing the recognition processing.

Abstract: A thermoelectric conversion material is a polycrystalline material composed of a plurality of crystal grains and has a composition represented by formula (I): Mg3+mSbaBi2−a−cAc. In the formula (I), A is at least one element selected from the group consisting of Se and Te, the value of m is greater than or equal to 0.01 and less than or equal to 0.5, the value of a is greater than or equal to 0 and less than or equal to 1.0, and the value of c is greater than or equal to 0.001 and less than or equal to 0.06. The thermoelectric conversion material has an Mg-rich region.
