[Prepublication] Abstract: In this paper we introduce a new framework and approach for convolutional neural network computation. By introducing layer functions that intelligently process complex-domain data in deep neural network architectures, we improve upon prior understanding and performance in complex-valued convolutional neural networks. Using novel derivations of convolutional, down-sampling, non-linear, and affine layers implemented in a complex-valued counterpart to Caffe, we proved results when evaluated against real-valued models in the context of environmental sound classification. Finally, we demonstrated these results are applicable to many other fields, including, but not limited to MRI imaging, signal processing, and LiDAR mapping.

Clips have been constructed from public field recordings gathered by the Freesound.org project. The dataset has been prearranged into 5 folds. Clips stemming from the same original source file are contained in a single fold.
File naming scheme:
category_id - category_name/fold_number-Freesound_clip_ID-take_letter.ogg
File details:
5-second-long recordings reconverted to a unified format:
- 44100 Hz,
- single channel (monophonic),
- Vorbis/Ogg compression @ 192 kbit/s.
The dataset can be downloaded as a single .zip file (~200 MB):
