Introduction of Activation Functions:

In the field of artificial intelligence and machine learning, functions play a crucial role in modeling and predicting various phenomena. These functions are mathematical representations that help in understanding and analyzing data. In this blog post, we will explore four types of functions commonly used in AI and machine learning: linear, sigmoid, exponential, and polynomial functions.

Note: Many functions are there but these 4 are predominantly used.

Functions:

  1. Threshold Function
  2. sigmoid function
  3. Rectifier Function
  4. Hyperbolic Tangent (tanh)
