Data Science and Machine Learning (Theory and Projects) A to Z - Deep Neural Networks and Deep Learning Basics: Training

The video introduces the concept of backpropagation in neural networks using a binary classification example. It explains the forward and backward pass processes, where the forward pass involves computing the loss with current parameters, and the backward pass updates parameters to minimize the loss. The video also touches on stopping criteria and technical issues in training, such as learning rates and network architecture. A preview of the next video is provided, which will cover more technical details like learning rates, stopping conditions, and network architecture.

What is the primary purpose of backpropagation in a neural network?

• To increase the complexity of the model

• To update the weights to minimize error

• To compute the output of the network

• To initialize the weights of the network

During the forward pass in a neural network, what is primarily computed?

• The error or loss

• The learning rate

• The updated weights
