Addressing Class Imbalance in Classification Problems of Noisy Signals by using Fourier Transform Surrogates

no code implementations20 Jun 2018 Justus T. C. Schwabedal, John C. Snyder, Ayse Cakmak, Shamim Nemati, Gari. D. Clifford

To quantify how well the distributions of the surrogates and the original data match, we evaluated a trained classifier on surrogates of correctly classified examples, and summarized these conditional predictions in a confusion matrix.

Detection of Paroxysmal Atrial Fibrillation using Attention-based Bidirectional Recurrent Neural Networks

1 code implementation7 May 2018 Supreeth P. Shashikumar, Amit J. Shah, Gari. D. Clifford, Shamim Nemati

We also demonstrate the cross-domain generalizablity of the approach by adapting the learned model parameters from one recording modality (ECG) to another (photoplethysmogram) with improved AF detection performance.

Subject Selection on a Riemannian Manifold for Unsupervised Cross-subject Seizure Detection

no code implementations1 Dec 2017 Samaneh Nasiri Ghosheh Bolagh, Gari. D. Clifford

Inter-subject variability between individuals poses a challenge in inter-subject brain signal analysis problems.

Fusing Continuous-valued Medical Labels using a Bayesian Model

no code implementations23 Mar 2015 Tingting Zhu, Nic Dunkley, Joachim Behar, David A. Clifton, Gari. D. Clifford

To address these problems, a Bayesian Continuous-valued Label Aggregator(BCLA) is proposed to provide a reliable estimation of label aggregation while accurately infer the precision and bias of each algorithm.
