Intensity Particle Flow SMC-PHD Filter For Audio Speaker Tracking
Yang Liu, Wenwu Wang, Volkan Kilic
Non-zero diffusion particle flow Sequential Monte Carlo probability hypothesis density (NPF-SMC-PHD) filtering has been recently introduced for multi-speaker tracking. However, the…
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…
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…
Bayesian inference for PCA and MUSIC algorithms with unknown number of sources
Viet Hung Tran, Wenwu Wang
Principal component analysis (PCA) is a popular method for projecting data onto uncorrelated components in lower dimension, although the optimal number of components is not specifi…
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…
Capsule Routing for Sound Event Detection
Turab Iqbal, Yong Xu, Qiuqiang Kong +1
The detection of acoustic scenes is a challenging problem in which environmental sound events must be detected from a given audio signal. This includes classifying the events as we…
