Question

Which of the following is correct about linear discriminant analysis ?
1)It maximizes the variance between the classes relative to the within class variance.
2)It minimizes the variance between the classes relative to the within class variance.
3)It maximizes the within class variance relative to the variance between classes.
4)None of these

Answer 1

Answer:

Option # 3

Explanation:

Among the four options given, the true statement is;

LDA maximizes the within class variance relative to the variance between classes

Linear Discriminant Analysis

Linear Discriminant Analysis is a transformation technique that is deployed to reduce the dimensions of the problem under consideration. By reduction dimension, it not only limits the computational cost but also reduces the probability of error
