Confusion matrix of CNN models.
(a) VGG16 outperforms other models, predicting 342 correctly identified COVID images and 333 correctly identified non-COVID images out of 691 samples |
(b) DenseNet121 has more layers, which reduces parameter efficiency and makes it more prone to overfitting. This model predicts 353 correctly identified COVID images and 321 correctly identified non-COVID images out of 691 samples |
(c) Even though MobileNet is faster in performance, it gives less accuracy compared to the VGG16 model. The MobileNet model predicts 334 correctly identified COVID images and 332 correctly identified non-COVID images |
(d) The number of parameters trained is larger compared to other models. Xception model predicts 341 correctly identified COVID images and 298 correctly identified non-COVID images |
(e) The NASNet architecture predicts 297 correct COVID images and 322 correct non-COVID images |
(f) EfficientNet predicts 144 correctly identified COVID images and 292 correctly identified non-COVID images with lower accuracy |
