Efficient and visualizable convolutional neural networks for COVID-19 classification using Chest CT

作者:

Highlights:

• 20 CNNs were trained and evaluated for COVID-19 Classification from Chest-CT scans.

• EfficientNetB5 attained highest accuracy(0.976), sensitivity(0.979), & F1 score (0.977).

• Model generalizes to new datasets & predicts with ∼ 0.1 s/img on GPU & ∼0.5 s on CPU.

• GradCAMs localized ground-glass opacities and consolidations.

• Intermediate Activation Maps demonstrated the model’s learning behavior.
