Answer 2

• Machine learning
• Natural language processing
• Speech recognition
• Machine vision

Question 3

What is an algorithm ?

Answer 3

Step-by-step procedure that describes how to perform a task. Often used for solving a problem or performing a computation.

Question 4

What are the 3 types of machine learning ?

Answer 4

• Unsupervised learning
• Supervised learning
• Reinforcement learning

Question 5

Unsupervised Learning

Answer 5

All forms of statistics where we don’t need labelled data (the algorithm “find out” how many subgroups make sense in the data)

Question 6

Supervised learning

Answer 6

Models trained on labelled data (Dog, Dog, Cat, Dog, Cat)

Question 7

Reinforcement Learning

Answer 7

Machine learns from series of actions in specific environnement (makes use of positive and negative rewards)
