The video tutorial provides an in-depth explanation of the training process of convolutional neural networks (CNNs). It covers the importance of understanding the underlying mathematics, even when using high-level frameworks like TensorFlow. The tutorial explains how to compute derivatives of the loss function with respect to network parameters, focusing on the convolution operation and Relu activation. It also discusses gradient descent and backpropagation techniques, and concludes with guidance on extending the concepts to deeper neural networks.
