Q

What is ML?

A

Programming computers to learn from observational data by identifying pattern and relationships.
These learned patterns are then used to analyze new data and make predictions or decisions.

Q

Semi-supervised learning ?

A
  • A mix of both supervised and unsupervised approaches, where the dataset has a small amount of labled data and a large amount of unlabled data.
