7. Select the sentence or sentences that are correct about cosine and correlation measures. The range of values that are possible for the cosine measure is [0, 1 if two objects have a cosine similarity of 1, they are identical if X and Y that have a mean of o, corrix.Y) = cos(X,Y) The range of values that are possible for the cosine measure is [0, 1]. If two objects have a cosine similarity of 1. they are identical 8. Which statements below are true for machine learning? Raw data can be utilized as the feature For predictive methods, a set of labeled examples is required Classification is a typical predictive data mining method 9. Select the correct sentence with respect to dimensionality reduction Singular Value Decomposition (SVD) is a typical technique of dimensionality reduction The dimensionality reduction is a mandatory preprocessing for all data mining techniques PCA and SVD is non-linear approach because these techniques use eigenvectors of the covariance matrix 10.
