Retrieving a small set of relevant and interesting objects from a large background class is challenging because classifiers can easily be overwhelmed by the large class. Classifiers have been developed that are more sensitive to the small class, and typically they optimize a ranking, or precision at the top. These measures can be costly because they often look at pairwise rankings. The classical approach...
The ant colony algorithm (ACA) has been successfully applied to several combinatorial optimization problems, but it has some shortcomings such as its slow computing speed, and it is easy to fall into local optimal. So a hybrid ant colony algorithm is proposed to optimize the ACA parameters. Firstly, the basic feasible solutions are solved by ACA, and then the quadratic optimal results are gotten by...
