The paper postulates that learn-ing to rank should adopt the listwise approach in which lists of objects are used as ‘instances’ in learning. The paper proposes a new probabilis-tic method for the approach. Specifically ...

Iterative methods attempt to improve on the heavy dependence on the accuracy of the initial pairwise alignments, which is the weak point of the progressive methods. Iterative methods optimize an objective function based on a selected alignment scoring method by assigning an initial global alignment and then realigning sequence subsets.
