What are the two main types of modelling techniques in AI?

The two main types of modelling techniques in AI are:

1. Rule-Based Models — These models follow specific rules set by humans. For example, "If the object is round and red, it is likely an apple." They offer simplicity and consistency but lack flexibility and learning capability.

2. Learning-Based Models — These models learn from data instead of following strict rules. They analyse patterns in the data and make decisions based on what they have learned. They can be further classified into Supervised, Un-supervised and Reinforcement learning.
