Which of the following is a scenario where you may want to use Random Project and not PCA
When we want to maximize the variance
When working with so many dimensions that PCA's performance becomes unacceptable for the situation
True or false: It is mandatory for us to specify the number of components/dimensions that we want Random Projection to reduce our dataset down into.
True, specifying the number of components is mandatory.
False, the number of components is optional and can be computed by the algorithm
