Application of blind source separation in sound source separation

Journal of Physics: Conference Series, 2019
Abstract The classic method for solving the cocktail party problem is by utilizing Independent Component Analysis (ICA) method to separate different sounds. Since ICA method deals with each frequency point of the audio signal individually, there is a classic sorting problem. However, for Independent Vector Analysis (IVA), which makes use

Two-Step Sound Source Separation: Training On Learned Latent Targets [PDF]

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2019
In this paper, we propose a two-step training procedure for source separation via a deep neural network. In the first step we learn a transform (and it’s inverse) to a latent space where masking-based separation performance using oracles is optimal.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Highly porous metal-organic framework glass design and application for gas separation membranes

Nature Communications
Crystalline metal-organic frameworks (MOFs) exhibit enormous potential application in gas separation, thanks to their highly porous structures and precise pore size distributions.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Circular Economy in Wastewater Management—The Potential of Source-Separating Sanitation in Rural and Peri-Urban Areas of Northern Finland and Sweden

Frontiers in Environmental Science, 2022
Current practices in wastewater management lead to inefficient recovery and reuse of nutrients and can result in environmental problems. Source separation systems have been shown to be an efficient way of recovering nutrients and energy from wastewaters,

Underdetermined blind source separation based on Fuzzy C-Means and Semi-Nonnegative Matrix Factorization [PDF]

, 2012
Conventional blind source separation is based on over-determined with more sensors than sources but the underdetermined is a challenging case and more convenient to actual situation.

Underdetermined source separation using a sparse STFT framework and weighted laplacian directional modelling

, 2017
The instantaneous underdetermined audio source separation problem of K-sensors, L-sources mixing scenario (where K < L) has been addressed by many different approaches, provided the sources remain quite distinct in the virtual positioning space spanned ...

Functional source separation from magnetoencephalographic signals [PDF]

Human Brain Mapping, 2006
AbstractWe propose a novel cerebral source extraction method (functional source separation, FSS) starting from extra‐cephalic magnetoencephalographic (MEG) signals in humans. It is obtained by adding a functional constraint to the cost function of a basic independent component analysis (ICA) model, defined according to the specific experiment under ...

Blind Audio Source Separation With Minimum-Volume Beta-Divergence NMF [PDF]

IEEE Transactions on Signal Processing, 2019
Considering a mixed signal composed of various audio sources and recorded with a single microphone, we consider in this paper the blind audio source separation problem which consists in isolating and extracting each of the sources.
