A multi-device dataset for urban acoustic scene classification
This provides a more variable dataset for researchers in audio classification, but it is incremental as it builds on previous DCASE challenges.
The paper introduces the TUT Urban Acoustic Scenes 2018 dataset for acoustic scene classification, recorded in six European cities with ten scenes and mobile device data, and evaluates a baseline CNN system using cross-validation.
This paper introduces the acoustic scene classification task of DCASE 2018 Challenge and the TUT Urban Acoustic Scenes 2018 dataset provided for the task, and evaluates the performance of a baseline system in the task. As in previous years of the challenge, the task is defined for classification of short audio samples into one of predefined acoustic scene classes, using a supervised, closed-set classification setup. The newly recorded TUT Urban Acoustic Scenes 2018 dataset consists of ten different acoustic scenes and was recorded in six large European cities, therefore it has a higher acoustic variability than the previous datasets used for this task, and in addition to high-quality binaural recordings, it also includes data recorded with mobile devices. We also present the baseline system consisting of a convolutional neural network and its performance in the subtasks using the recommended cross-validation setup.
