You can form A using the commands
A = sparse(1:m,train(:,1),train(:,3),m,n) + ...
(c) Use the maximum likelihood estimate a found in part (b) to predict the outcomes of next
year’s tournament games, given in the matrix test, using y (i) = sign(ˆj (i) − ak(i) ). Compare
these predictions with the actual outcomes, given in the third column of test. Give the
fraction of correctly predicted outcomes.
The games played in train and test are the same, so another, simpler method for predicting
the outcomes in test it to just assume the team that won last year’s match will also win this
year’s match. Give the percentage of correctly predicted outcomes using this simple method.
6.5 Estimating a vector with unknown measurement nonlinearity. (A speciﬁc instance of exercise 7.9
in Convex Optimization.) We want to estimate a vector x ∈ Rn , given some measurements
yi = φ ( a T x + v i ) ,
i i = 1, . . . , m. H...
