Deep Learning - Crash Course 2023 - Sigmoid Intuition

The video tutorial explains the sigmoid function, focusing on the logistic function with parameters West and B. It demonstrates how varying these parameters affects the sigmoid plot. Increasing West makes the transition from 0 to 1 sharper, while decreasing it smooths the transition. Setting West to zero results in a straight line, and negative values flip the plot. The parameter B shifts the sigmoid curve horizontally. The video concludes with a preview of applying these insights to data fitting in the next tutorial.

What inference can be made about the relationship between the values of West and the steepness of the sigmoid curve?

Describe the effect of changing the value of B on the sigmoid function.
