Random Data Augmentation based Enhancement: A Generalized Enhancement Approach for Medical Datasets

1 code implementation3 Oct 2022 Sidra Aleem, Teerath Kumar, Suzanne Little, Malika Bendechache, Rob Brennan, Kevin McGuinness

To evaluate the generalization of the proposed method, we use four medical datasets and compare its performance with state-of-the-art methods for both classification and segmentation tasks.

Investigating Multi-Feature Selection and Ensembling for Audio Classification

no code implementations15 Jun 2022 Muhammad Turab, Teerath Kumar, Malika Bendechache, Takfarinas Saber

To investigate this role, we conduct an extensive evaluation of the performance of several cutting-edge DL models (i. e., Convolutional Neural Network, EfficientNet, MobileNet, Supper Vector Machine and Multi-Perceptron) with various state-of-the-art audio features (i. e., Mel Spectrogram, Mel Frequency Cepstral Coefficients, and Zero Crossing Rate) either independently or as a combination (i. e., through ensembling) on three different datasets (i. e., Free Spoken Digits Dataset, Audio Urdu Digits Dataset, and Audio Gujarati Digits Dataset).
