Original Kurzfassung:
Designing lightweight models that require limited computational resources and can operate on edge devices is a major trajectory in deep learning research. In the context of Acoustic Scene Classification (ASC), the DCASE community hosts an annual challenge on low-complexity ASC, contributing to the research on Knowledge Distillation (KD), Model Pruning, Quantization and efficient neural network design. In this work, we propose a system that contributes to the latter by introducing CP-Mobile, a lightweight CNN architecture constructed of residual inverted bottleneck blocks and Global Response Normalization. Furthermore, we improve Knowledge Distillation by showing that ensembling CNNs and Audio Spectrogram Transformers form strong teacher ensembles. Our proposed system improves the results on the TAU Urban Acoustic Scenes 2022 Mobile development dataset by around 5 percentage points in accuracy compared to the top-ranked submission for Task 1 of the DCASE 22 challenge and achieves the top rank in the DCASE 23 challenge.
