Digital Phenotype Representation by Statistical, Information Theory, Data-Driven Approach with Digital Health Data

ICASSP 2023accepted

Digital phenotyping (DP) is a multidisciplinary field of science that quantifies the individual level phenotype through active and passive data. Although DP is a multidisciplinary field, there lacks a technical and a systematic approach to representing DP. This work proposes the development of digit…

Augmenting Dysphonia Voice Using Fourier-based Synchrosqueezing Transform for a CNN Classifier

ICASSP 2019accepted

The challenge of dysphonia voice studies is always the small dataset. It is difficult to apply more sophisticated deep learning techniques without overfitting or underfitting. Convolutional neural network (CNN) is a powerful classifier that requires a large amount of training data. Data augmentation…

First-Order Difference Energy Regularization for Enhancing Reconstruction Performance in Compressive Sensing of Foot-Gait Signals

ICASSP 2018accepted

A new method for the regularization of the objective function for the reconstruction of the foot-gait signal from compressively sensed measurements is proposed. The method is based on using the l2 norm of the first-order difference to regularize the objective function. The state-of-the-art first-ord…
