Fast Iterative Shrinkage for Signal Declipping and Dequantization
Lucas Rencker, Francis Bach, Wenwu Wang +1
We address the problem of recovering a sparse signal from clipped or quantized measurements. We show how these two problems can be formulated as minimizing the distance to a convex…
Referenceless Performance Evaluation of Audio Source Separation using Deep Neural Networks
Emad M. Grais, Hagen Wierstorf, Dominic Ward +2
Current performance evaluation for audio source separation depends on comparing the processed or separated signals with reference signals. Therefore, common performance evaluation…
DCASE 2018 Challenge Surrey Cross-Task convolutional neural network baseline
Qiuqiang Kong, Turab Iqbal, Yong Xu +2
The Detection and Classification of Acoustic Scenes and Events (DCASE) consists of five audio classification and sound event detection tasks: 1) Acoustic scene classification, 2) G…
Sparse Recovery and Dictionary Learning from Nonlinear Compressive Measurements
Lucas Rencker, Francis Bach, Wenwu Wang +1
Sparse coding and dictionary learning are popular techniques for linear inverse problems such as denoising or inpainting. However in many cases, the measurement process is nonlinea…
Sound Event Detection and Time-Frequency Segmentation from Weakly Labelled Data
Qiuqiang Kong, Yong Xu, Iwona Sobieraj +2
Sound event detection (SED) aims to detect when and recognize what sound events happen in an audio clip. Many supervised SED algorithms rely on strongly labelled data which contain…
Raw Multi-Channel Audio Source Separation using Multi-Resolution Convolutional Auto-Encoders
Emad M. Grais, Dominic Ward, Mark D. Plumbley
Supervised multi-channel audio source separation requires extracting useful spectral, temporal, and spatial features from the mixed signals. The success of many existing systems is…
