Recursive feature elimination.
Functions
BibTeX (\*args, \*\*kwargs) |
Perform no good and no bad |
Doi (\*args, \*\*kwargs) |
Perform no good and no bad |
copy (x) |
Shallow copy operation on arbitrary Python objects. |
maxofabs_sample () |
Returns a mapper that finds max of absolute values of all samples. |
mean_mismatch_error (predicted, target) |
Computes the percentage of mismatches between some target and some predicted values. |
Classes
BestDetector ([func, lastminimum]) |
Determine whether the last value in a sequence is the best one given some criterion. |
BinaryFxNode (fx, space, \*\*kwargs) |
Extract a dataset attribute and call a function with it and the samples. |
ClassifierError (clf[, labels, train]) |
Compute (or return) some error of a (trained) classifier on a dataset. |
ConditionalAttribute ([enabled]) |
Simple container intended to conditionally store the value |
FeatureSelectionClassifier (clf, mapper, \*\*kwargs) |
This is nothing but a MappedClassifier . |
FractionTailSelector (felements, \*\*kwargs) |
Given a sequence, provide Ids for a fraction of elements |
IterativeFeatureSelection (fmeasure, ...[, ...]) |
Notes |
NBackHistoryStopCrit ([bestdetector, steps]) |
Stop computation if for a number of steps error was increasing |
ProxyClassifier (clf, \*\*kwargs) |
Classifier which decorates another classifier |
ProxyMeasure (measure[, skip_train]) |
Wrapper to allow for alternative post-processing of a shared measure. |
RFE (fmeasure, pmeasure, splitter[, ...]) |
Recursive feature elimination. |
Repeater (count[, space]) |
Node that yields the same dataset for a certain number of repetitions. |
Sensitivity (clf[, force_train]) |
Sensitivities of features for a given Classifier. |
SplitRFE (lrn, partitioner, fselector[, ...]) |
RFE with the nested cross-validation to estimate optimal number of features. |
Splitter (attr[, attr_values, count, ...]) |
Generator node for dataset splitting. |
