Orthogonal Features-based EEG Signal Denoising using Fractionally Compressed AutoEncoder

no code implementations16 Feb 2021 Subham Nagar, Ahlad Kumar, M. N. S. Swamy

The architecture makes use of fractional calculus to calculate the gradients during the backpropagation process, as a result of which a new hyper-parameter in the form of fractional order ($\alpha$) has been introduced which can be tuned to get the best denoising performance.

Deep learning-based methods have achieved state-of-the-art performance; however, one of major limitations is that the learning-based methods may suffer from the multi-site issue, that is, the models trained on a dataset from one site may not be applicable to the datasets acquired from other sites with different imaging protocols/scanners.

A Variational Step for Reduction of Mixed Gaussian-Impulse Noise from Images

no code implementations1 Nov 2018 Mohammad Tariqul Islam, Dipayan Saha, S. M. Mahbubur Rahman, M. Omair Ahmad, M. N. S. Swamy

However, ROF cannot completely remove the heavy tail of the noise distribution originating from the IN and thus the denoising performance can be suboptimal.
