Rename to a more sensible name

Parallel predict and sparse support

Started MultiOutput documentation

Move code to new file multioutput.py

Continuing the move to new multioutput module

Added sample weight support

Better test for sample weights and actually support weights

Added a new test using weighted vs repeated samples to
test sample weight support. Uncovered that weights
were not actually passed on to underlying estimator.

Comment on multiprocess overheads

Move parallel_helper to utils.fixes

This helper works around a python2 limitation on pickling
instance methods

Example of multi-output regression with gradient boosting

Switch to uniform weighted score and updated example

The example now uses a RF with and without the MultiOutput
meta estimator

Added note for removing `score` method

[MRG + 1] Isolation forest - new anomaly detection algo
2015-10-24 19:53:55 +02:00
ngoix a75eb63194 iforest
example + benchmark

explanation

make some private functions + fix public API

IForest using BaseForest base class for trees

debug + plot_iforest

classic anomaly detection datasets and benchmark

small modif

BaseBagging inheritance

shuffle dataset before benchmarking

BaseBagging inheritance

remove class label 4 from shuttle dataset

pep8 + rm shuttle.csv bench_IsolationForest.png + doc decision_function

add tests

remove comments

fetching kddcup99 and shuttle datasets

fetching kddcup99 and shuttle datasets

pep8

fetching kddcup99 and shuttle datasets

pep8

new files iforest.py and test_iforest.py

sc

alternative to pandas (but very slow)
in kddcup99.py

faster parser

sc

pep8 + cleanup + simplification

example outlier detection

clean and correct

idem

random_state added

percent10=True in benchmark

mc

remove shuttle + minor changes

sc

undo modif on forest.py and recompile cython on _tree.c

fix travis

cosmit

change bagging to fix travis

Revert "change bagging to fix travis"

This reverts commit 30ea500eb818c7a2c6ea5c3d63e75c6935aa3a35.

add max_samples_ in BaseBagging.fit to fix travis

mc

API : don't add fit param but use a private _fit + update tests + examples to avoid warning

adapt to the new structure of _tree.pyx

cosmit

add performance test for iforest

add _tree.c _utils.c _criterion.c

TST : pass on tests

remove test

relax roc-auc to fix AppVeyor

add test on toy samples

Handle depth averaging at python level

plot example: rm html add png

load_kddcup99 -> fetch_kddcup99 + doc
