Choose the best
a. the classification methods such as k-nearest-neighbors, classification tree, neural network, support vector machine, etc. are the supervised learning methods that try to discover optimal or sub-optimal classification boundaries.
b. the ultimate goal of these supervised learning methods such as k-nearest-neighbors, classification tree, neural network, support vector machine, etc. is to generate a model that will simulate some mathematic classification function to minimize the classification error.
c. both a. and b.
d. neither a. nor b.
