This is data mining related. Based on the table
a) TRUE OR FALSE. Consider a generalized tuple of the type {A=V}, where A is outlook or temperature and V is chosen from the set of possible values of the corresponding attribute (according to the data). There exists a set of such generalized tuples that jointly cover all the tuples in the data from one class only.
b) Which formula applies to computing the entropy of the class distribution (class attribute is play)? I=-3/9*log(3/9)-(6/9)*log(6/9) OR I=-3/9*log(3/9)-3/9*log(3/9)-3/9*log(3/9)
c) How many near hits does the tuple
d) How many near misses does the tuple
