Various boosting algorithms in matlab/C,C++.

All the codes here are provided "AS IS", without any guarantee. Do not try to sue me!

1. Codes for the paper "Positive Semidefinite Metric Learning with Boosting", by C. Shen, J. Kim, L, Wang and A. van den Hengel, NIPS 2009. The extended version can be downloaded here http://arxiv.org/abs/0910.2279

PLEASE NOTE:

This package doesn't implement the cross-valiation part. Same as in AdaBoost; for BoostMetric, you need to determine when to stop the iteration; and this might have a significant impact on the final test error and of course, running time.

We found that some papers have used the default value for ``pars.maxiter'' (default 1000) and reported that, BoostMetric has very poor peformance. This is not very fair for BoostMetric You need to cross-validate ``pars.maxiter''!
