Cross-task learning for audio tagging, sound event detection spatial localization: DCASE 2019 baseline systems
This work provides incremental baseline systems for researchers in audio processing, helping benchmark performance in the DCASE 2019 challenge.
The paper tackled the DCASE 2019 challenge by proposing generic cross-task baseline systems using convolutional neural networks (CNNs) for audio tasks like tagging and detection, finding that a 9-layer CNN with average pooling performed well across most tasks.
The Detection and Classification of Acoustic Scenes and Events (DCASE) 2019 challenge focuses on audio tagging, sound event detection and spatial localisation. DCASE 2019 consists of five tasks: 1) acoustic scene classification, 2) audio tagging with noisy labels and minimal supervision, 3) sound event localisation and detection, 4) sound event detection in domestic environments, and 5) urban sound tagging. In this paper, we propose generic cross-task baseline systems based on convolutional neural networks (CNNs). The motivation is to investigate the performance of a variety of models across several tasks without exploiting the specific characteristics of the tasks. We looked at CNNs with 5, 9, and 13 layers, and found that the optimal architecture is task-dependent. For the systems we considered, we found that the 9-layer CNN with average pooling is a good model for a majority of the DCASE 2019 tasks.
