Abstract
A learning network includes: a first extraction unit that extracts each feature vector of different pieces of teaching data designated in a support set using a first inception neural network that extracts a feature vector of time-series data by convolution layers with different filter sizes; a second extraction unit that extracts a feature vector of teaching data designated in a query set using a second inception neural network that extracts a feature vector of time-series data by a plurality of convolution layers with different filter sizes; and a learning unit that updates a network parameter of the learning network such that a relative distance between feature vectors of teaching data of the query set and of a positive sample of the support set is small and a relative distance between feature vectors of teaching data of the query set and of a negative sample of the support set is large.
