Deep Learning - Crash Course 2023 - Sigmoid Neuron Introduction

The video tutorial explains the concept of a sigmoid neuron, which uses a smooth sigmoid function instead of a step function for output. It introduces the logistic function, detailing its parameters: weights and bias. The tutorial demonstrates plotting the sigmoid function using Python libraries like numpy and matplotlib. It covers the sigmoid neuron's ability to output real numbers between 0 and 1, useful for regression and binary classification. The video also discusses the loss function and gradient descent as methods for optimizing the weights and bias in the model.
