a function inside machine learning

%A function to compute the maximum sparse target alignment vector between matrix
%K and vector y
%We just use the example with the highest target alingment
numExamples = size(Kj, 1);

[alignments, bs] = sparseAlignments(K, Kj, Y, Yj, columnIndices); 

[maxAlignment, i] = max(alignments);
b = zeros(numExamples, 1); 
b(i) = bs(i);
