Big data
(f) are the conditional probabilities for the traning set (20
observations)
(g) there are 3 new future data you want to predict
1 st one to preditct is Gender=male, type = lux, size=medium,
you predict what class(C0. C1)?

L (1) Based on the given training date set, calculate the probabilities required for a Naïve Bayers classifier. Using Laplace smoothing for k=1 estimate to smooth the following probability estimates: P(C=CO) = ? P(C=C1)= ? P(G=MC=CO) = ? P(G=MC=C1) = ? P(G=F|C=CO) = ? P(G=F|C=C1) = ? P(T =F|C=CO) = ? P(T =F|C=C1)= ? P(T ES|C=CO) = ? P(T = |C=C1) = ? P(T =LC=C0) = ? P(T =L|C=C1)= P(S=S|C=CO) = ? P(S=S|C=C1) = ? P(S=M|C=CO) = ? P(S=M|C=C1) = ? P(SELİC=CO) = ? P(S=LIC=C1) = ? P(S=E|C=CO) = ? P(S=E|C=C1) = ? [18 marks) (g) Using your Naïve Bayers model with Laplace smoothing for k=1 estimate to classify the following three records. [3 marks] Gender Type Size M F F 2 LLLL | Luxury | Medium | Luxury | Large 1 Luxury | E Large
