Deep CNN

Neurons

Limitations

VGG16

33 × 106

This model is slow in training and computationally expensive due to many trainable parameters

AlexNet

24 × 106

Due to the large number of trainable neurons, AlexNet is also costly. Moreover, the model is unable to detect all high-dimensional spatial features

ResNetXt

23 × 106

ResNeXt is a fifty-layer deep CNN model that can extract high-dimensional features that require a large training dataset. In addition, it cannot be used for real-time applications due to the significant number of trainable parameters

DenseNet-121

7.2 × 106

DenseNet-121 has significantly less trainable parameters. However, this model's performance is less compared to other state-of-the-art models
