Learning device, inference device, and learning method

Abstract

In the present invention, a learning device (100) comprises: an object information acquisition unit (120) that acquires object information relating to an object, said object information including object presence information indicating whether the object is present; a delay profile generation unit (113) that generates a delay profile on the basis of reception waves received by a reception antenna element when the reception antenna element receives waves produced by transmission waves transmitted from a transmission antenna element that have reflected off the object; a training data generation unit (130) that, on the basis of the object information acquired by the object information acquisition unit (120) and the delay profile generated by the delay profile generation unit (113), generates training data for generating a trained model; and a machine learning unit (140) that performs machine learning of the training data generated by the training data generation unit (130) and generates a trained model that outputs a detection result for a new object on the basis of the a delay profile input generated by the delay profile generation unit (113).
