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

The video tutorial explains the concept of decision boundaries in neural networks. It begins by introducing the idea that each neuron in a neural network acts as a computational unit representing a hyperplane in the input space. In a two-dimensional space, neurons represent lines, and these lines can be used to classify data points into different classes. The tutorial further explains how increasing the number of neurons allows for a smoother approximation of decision boundaries. In higher-dimensional spaces, neurons represent hyperplanes, and their intersections form complex decision boundaries. The video emphasizes the role of neurons in defining piecewise linear boundaries and how they can model continuous functions.
