Jiaming Yuan d262503781 [R] Implement new save raw in R. (#7571) 2022-01-22 20:55:47 +08:00
Jiaming Yuan ef4dae4c0e [dask] Add scheduler address to dask config. (#7581) 
- Add user configuration.
- Bring back to the logic of using scheduler address from dask.  This was removed when we were trying to support GKE, now we bring it back and let xgboost try it if direct guess or host IP from user config failed.

Jiaming Yuan 5ddd4a9d06 Small cleanup to tests. (#7585)

Jiaming Yuan 529cf8a54a Configure cub version automatically. (#7579)

instead of using internal cub function to accept inputs larger than maximum integer.

Jiaming Yuan 001503186c Rewrite approx (#7214) 
This PR rewrites the approx tree method to use codebase from hist for better performance and code sharing.

The rewrite has many benefits:
- Support for both `max_leaves` and `max_depth`.
- Support for `grow_policy`.
- Support for mono constraint.
- Support for feature weights.
- Support for easier bin configuration (`max_bin`).
- Support for categorical data.
- Faster performance for most of the datasets. (many times faster)
- Support for prediction cache.
- Significantly better performance for external memory.
- Unites the code base between approx and hist.
