This implementation can be applied to any estimator, but uses trees by default. Typically, the simple learners called weak learners can be rules as simple as taking simple thresholds of observed quantities this will form decision stumps. However, the Python parallel execution model via multiple processes has an overhead in term of computing time and of memory usage. It would be a pitty to throw away either those observations, or some descriptors. I am just giving a quick list here for completness see also the full list of changes:

Mehdi, from the website you can guess the url that used to be online.

This is explained because these datasets do not display a heavily-structured low ambient dimension. The full list of API changes can be found on the change log. It would be a pitty to throw away either those observations, or some descriptors.

Scikit-learn 0.14 release: features and benchmarks

The trees random forests and scikot-learn were massively sped up by Gilles Louppebringing them to par with the fastest libraries see benchmarks below Jake Vanderplas improved the BallTree and implemented fast KDTrees for nearest-neighbor search benchmarks below.

However, building a tree-like data structure ahead of time can make this query cost only log n. On the digits dataset samples, scikit-leqrn This question appears to be off-topic. The users who voted to close gave this specific reason: I think that it also looks prettier: LinuxmacOSWindows.

These settings are well suited to very big data. The implementation in scikit-learn 0. This is explained by the fact that as the dimensionality grows, the number of planes required to break up the space grows too. This is due to the more elaborate choice of cutting planes. Performance improvements Many part of the codebase got speed-ups, with a focus on making scikit-learn more scalable for bigger data.

Major API changes The scoring parameter One of the benefits of scikit-learn over other learning packages is that it can set parameters to maximizing a prediction score.

Active 3 years, 5 months ago. The huge spike correspond to the second international sprint: In higher dimensions that can be achieved by building a KDTreemade of planes dividing the space in half-spaces, or a BallTreemade of nested balls. Overall, the new KDTree in scikit-learn seem to be giving an excellent compromise. Views Read Edit View history.

Importantly, the scaling is different: If your data-acquisition has failures, human or material, you can easily end up with some descriptors missing for some observations.

It turns out that benching statistical learning code is very hard, because speed depends a lot on the properties of the data. Instead, describe the problem and what has been done so far to solve it. We can see that no approach win on all counts.

As of [update]scikit-learn is under active development. I have tagged and released the scikit-learn 0. Other libraries, such as WiseRfhave performance claims compared to us.

For some scikit-leagn, Ubuntu Unicorn Meta Zoo 9: The productivity of such a sprint is huge, both because we get together and work efficiently, but also because we get back home and keep working I have been sleep deprived because of late-night hacking ever since the sprint. Many part of the codebase got speed-ups, with a focus on making scikit-learn more scalable for bigger data. The scikit-learn project started as scikits.
