Hi all,
Just a few comments about this SLEP from a contributor and user of the
library :).
I think it is important for users to be able to quickly and easily
know/learn which arguments should be keyword arguments when they use
scikit-learn. As a user, I do not want to have to double check each
Hi,
The default score used by GridSearchCV is the one of the estimator; for
KernelDensity it’s the total log likelihood.
As far as I know it is not possible to have different bandwidths.

Hi Sergio,
In IsolationForest, BaseBagging is applied with ExtraTreeRegressor as
base_estimator. Algorithm 2 (iTree) of the original paper is thus
implemented in ExtaTreeRegressor.
The forest is implemented thanks to the bagging procedure.
HTH,

Maybe run ‘make clean’ before running pip install ...

Hi Abhishek,
Could you provide a small code snippet? I don't think the random_state
parameter should influence the result of the OneClassSVM as there is no
probability estimation for this estimator.

You can also have a look at "Effective Computation in Physics" by Anthony
Scopatz and Kathryn D. Huff.
It gives a very good overview of Python/numpy/pandas...

In fact `pip install --editable .` is the instruction given at the end of
the Advanced installation instructions
http://scikit-learn.org/stable/developers/advanced_installation.html#testing
.
I will submit a PR to recommend this in the Contributing section as well.

Hi all,
For a develop install it is suggested in the contributing section of the
website http://scikit-learn.org/stable/developers/contributing.html to do:
python setup.py develop
However I read on stackoverflow that the preferred way to do this is now to
use pip instead of using setuptools
Hi Ady,
Overfitting is a possible explanation. If your model learnt your normal
scenarios too well then every abnormal data will be predicted as abnormal
(so you will have a good performance for anomalies) however none of the
normal instances of the test set will be in the normal region (so you
Hi,
About your question on how to learn the parameters of anomaly detection
algorithms using only the negative samples in your case, Nicolas and I
worked on this aspect recently. If you are interested you can have look at:
- Learning hyperparameters for unsupervised anomaly detection:
Hi,
There was a pull request for the svdd
https://github.com/scikit-learn/scikit-learn/pull/5899
But it has been closed recently...
Note that if you apply the OCSVM with the rbf kernel it is equivalent to
the svdd.
