Implementing skip connections in keras

I am implementing ApesNet in keras. It has an ApesBlock that has skip connections. How do I add this to a sequential model in keras? The ApesBlock has two parallel layers that merge at the end by element-wise addition.

Training Resnet deep neural network from scratch

I need to gain some knowledge about deep neural networks. For a 'ResNet' very deep neural network, we can use transfer learning to train a model. But Resnet has been trained over the ImageNet dataset. So their pre-trained weights can be used to…

Massive overfit during resnet50 transfer learning

This is my first attempt at doing something with CNNs, so I am probably doing something very stupid - but can't figure out where I am wrong... The model seems to be learning fine, but the validation accuracy is not improving (ever - even after the…
