Student's t statistic is nding applications today that were never envisaged
when it was introduced more than a century ago. Many of these applications
rely on properties, for example robustness aga...

2010/3/9
We empirically investigate the best trade-off between sparse and uniformly-
weighted multiple kernel learning (MKL) using the elastic-net regular-
ization on real and simulated datasets. We find tha...
