Deep Learning - Deep Neural Network for Beginners Using Python - Deep Learning Algo Overview

The video tutorial explains the core steps of a deep learning algorithm, focusing on feedforward operations and backpropagation. Initially, the feedforward operation is used to generate the model's output, Y hat, which is then compared to the desired output, Y, to calculate error. The tutorial emphasizes the importance of backpropagation, which involves running the feedforward operation backwards to adjust weights and reduce error. This iterative process continues until a model with minimal error is achieved, highlighting the simultaneous use of feedforward and backpropagation techniques to develop an effective deep learning model.
