Abstract (in Japanese) (See Japanese page) 
(in English) Recently, acoustic scene classification using a beamformer with multi-channel signals as input has been proposed. Generally, prior information such as the direction of arrival of the target sound is necessary to generate the spatial filter of the beamformer. However, it is difficult to apply a beamformer as a pre-processing method because it is not obvious what kind of sound is of interest in a particular acoustic scene and in which direction the sound is located. We have devised an approach in which the networks of a spatial filter generator and classifier are concatenated and simultaneously optimized. The goal of this approach is to automatically learn what sounds to be focused on and automatically generate spatial filters to emphasize them,
without requiring any prior information such as the direction of arrival of the target sound or a reference signal. This paper proposes a loss function that incorporates the idea of the MVDR (Minimum Variance Distortionless Response) beamformer and verifies its effectiveness through experiments.
