Jiaming Yuan	58a6723eb1	Initial support for multioutput regression. (#7514) ... * Add num target model parameter, which is configured from input labels. * Change elementwise metric and indexing for weights. * Add demo. * Add tests.	2021-12-18 09:28:38 +08:00
Jiaming Yuan	5b1161bb64	Convert labels into tensor. (#7456) ... * Add a new ctor to tensor for `initilizer_list`. * Change labels from host device vector to tensor. * Rename the field from `labels_` to `labels` since it's a public member.	2021-12-17 00:58:35 +08:00
Jiaming Yuan	85cbd32c5a	Add range-based slicing to tensor view. (#7453)	2021-11-27 13:42:36 +08:00
Jiaming Yuan	557ffc4bf5	Reduce base margin to 2 dim for now. (#7455)	2021-11-27 00:46:13 +08:00
Jiaming Yuan	d33854af1b	[Breaking] Accept multi-dim meta info. (#7405) ... This PR changes base_margin into a 3-dim array, with one of them being reserved for multi-target classification. Also, a breaking change is made for binary serialization due to extra dimension along with a fix for saving the feature weights. Lastly, it unifies the prediction initialization between CPU and GPU. After this PR, the meta info setter in Python will be based on array interface.	2021-11-18 23:02:54 +08:00
