Question 1

What does witness rate refer to in multiple instance learning?

Answer 1

In Multiple Instance Learning (MIL), the witness rate refers to the proportion of positive instances within a positive bag.

(Fraction of samples indicating the right class)

Question 2

What is multiple instance learning?

Answer 2

Multiple Instance Learning (MIL) is a type of machine learning where data comes in bags (groups of instances), and:

A bag is labeled, not the individual instances.

A positive bag means at least one instance is positive.

A negative bag means all instances are negative.
