Journal ArticleDOI
Improved computerized cardiac auscultation by discarding artifact contaminated PCG signal sub-sequence
A Kishore Kumar,Goutam Saha +1 more
TL;DR: A novel method of detection of artifact in heart sound is presented which uses a fusion of tunable Q-wavelet transform and signal second difference with median filter to detect the artifact-infected sub-sequences.
Journal ArticleDOI
Switch or stay? Automatic classification of internal mental states in bistable perception.
Susmita Sen,Syed Naser Daimi,Katsumi Watanabe,Kohske Takahashi,Joydeep Bhattacharya,Goutam Saha +5 more
TL;DR: This study presents an automatic classification of endogenous mental states involved in bistable perception by establishing brain-behavior relationships at the single-trial level and investigates the temporal fluctuations of these internal mental representations as captured by the classifier model.
Journal ArticleDOI
On the use of perceptual Line Spectral pairs Frequencies and higher-order residual moments for Speaker Identification
TL;DR: An investigation is carried out to extract LSF from perceptually modified speech and a new feature set extracted from the residual signal is proposed, which shows improved performance.
Journal Article
In Search of an SVD and QRcp Based Optimization Technique of ANN for Automatic Classification of Abnormal Heart Sounds
Samit Ari,Goutam Saha +1 more
TL;DR: An optimization technique that involves Singular Value Decomposition (SVD) and QR factorization with column pivoting (QRcp) methodology to optimize empirically chosen over-parameterized ANN structure is presented.
Journal ArticleDOI
Two-level fusion-based acoustic scene classification
Shefali Waldekar,Goutam Saha +1 more
TL;DR: A two-level hierarchical framework for ASC wherein finer labels follow coarse classification, which is compared with baseline methods using detection and classification of acoustic scenes and events and found to be superior in terms of classification accuracy.
