I already have the answer, but I don't know how 's the answer comes from.Please help me explan the question step by step thank you! 2.Given the following data set, we apply a naïve Bayesian (NB) classifier to predict the Health status.Each patient is described by Temp={H,N}, BP={H,N}, Test1={P,N} and Test2={P,N}. The class is Health={D,H}.IDTempВРTest1Test2Health1234HH.N6754HNNPD2345NHPP2457HH.PND3567NHP7532NH.NNH1456NNNH1468HNNNH8989HNNPH9876HNNNHFor a new patient, ID 9999, with Temp=H, BP=H, Test1=N, Test2=P, is he/she Healthy (H) or Diseased (D)?Show (a) the value of each term in your NB classifier, and (b) your prediction.Answer:P_temp(H/D)=3/5, P_temp(N/D)=2/5P_temp(H/H)=3/5, P_temp(N/H)=2/5P_BP(H/D)=4/5, P_BP(N/D)=1/5P_BP(H/H)=1/5, P_BP(N/H)=4/5P_Test1(P/D)=4/5, P_Test1(N/D)=1/5P_Test1(P/H)=0/5, P_Test1(N/H)=5/5P_Test2(P/D)=3/5, P_Test2(N/D)=2/5P_Test2(P/H)=1/5, P_Test2(N/H)=4/5new patient A: Temp=H, BP=H, Test1=N, Test2=PS((H,H,N,P),D) = 3/5 * 4/5 * 1/5 * 3/5 = 0.0576S((H,H,N,P),H) = 3/5 * 1/5 * 5/5 * 1/5 = 0.024S((H,H,N,P),D) > S((H,H,N,P),H)So predict A as class D.

2. Given the following data set, we apply a naïve Bayesian (NB) classifier to predict the Health status. Each patient is described by Temp={H,N}, BP={H,N}, Test1=(P,N} and Test2=(P,N}. The class is Health={D,H). ID Temp BP Testl Test2 Health 1234 H P N D 6754 H P. D. 2345 N H P. D. 2457 H. N D 3567 N H P D 7532 1456 N N 1468 N 8989 H N H. 9876 H N N N H.
