please help machine learning question

Choose the correct log-likelihood for multi-class logistic regression with the data given above. A. LL()=i=1N21exp[2(xi)2] B. LL(B)=i=1Nc=1CyN(xiTelogi=1Cexp{xiTk}) C. LL()=2Nlog2i=1N2(xi)2 D. LL(0,)=i=1Nlog[1+exp{1(0+xiT)}] Question 10 The number of parameters in the model is Question 11 Which of the following is TRUE about unsupervised leaning? Unsupervised learning requires labeled observations. Clustering is a type of unsupervised leaming. Unsupervised leaming does not require labeled observations. Unsupervised leaming is less accurate than supervised leamire
