In K-NN, is the query time longer than the training time?

• Yes

• No

Which of the following options is true about the k-NN algorithm?

• It can only be used for classification

• It can only be used for regression

• It can be used for both classification and regression

In K-NN, what is the effect of increasing/decreasing the value of K?

• The boundary becomes smoother with increasing values of K

• Smoothness of the boundary does not depend on the value of K

• The boundary becomes smoother with decreasing values of K

• None of these

For embedded applications (i.e. running on a smartphone), what is the most appropriate family of algorithm?

• Eager learners

• Lazy learners

Given d the distance between a point of the dataset and the query point, which of the following weight functions is appropriate for Distance-Weighted k-NN?

• w = exp( -d )

• w = log ( min ( 0.25 * d, 1 ) )

• w = -d
