Current activities

Since January 1st, 2014, I am researcher in machine learning and signal processing at Inria in the speech processing group of the Inria Nancy - Grand Est research center.

My interests are:

• Signal models and machine learning
• Time series modelling: alpha-stable, Gaussian processes
• Dimension reduction techniques: NMF/NTF, etc
• Kernel additive modelling (KAM)
• Inference and algorithms
• Applications
• Audio source separation
• Speech enhancement

Publications

Software

• My Matlab FileExchange webpage
• Light implementation of Nonnegative Tensor Factorization (NTF) in PYTHON
and MATLAB (more details here for the matlab version)
• Easy to use scale-space peak detections
• Picks detection and grouping: peaksandgroups
• Scale-space picks detection: pickpeaks
• Easy to use code for computing STFT and inverse on MATLAB
• Voice-Music separation with KAM: MATLAB implementation
• Harmonic/percussive separation with KAM: MATLAB implementation
• Online voice/music separation: destructive commons (external webpage)

Datasets

• The ccmixter dataset for voice-music separation
• The Demixing Secrets dataset (DSD100): 100 professionally produced full tracks with separated bass, drums, vocals and other, in stereo 44.1kHz.
