Multivariate Pattern Analysis in Python |
Bases: object
Determine whether the last value in a sequence is the best one given some criterion.
Initialize with number of steps
Parameters: |
|
---|
Bases: mvpa.misc.state.ClassWithCollections
Base class to implement functors to select some elements based on a sequence of values.
Note
Available state variables:
(States enabled by default are listed with +)

Please refer to the documentation of the base class for more information:
Cheap initialization.
Parameters: |
|
---|
Bases: mvpa.featsel.helpers.StoppingCriterion
Stop computation if the latest error drops below a certain threshold.
Initialize with threshold.
Parameter: | threshold (float [0,1]) – Error threshold. |
---|
Bases: mvpa.featsel.helpers.TailSelector
Given a sequence, provide set of IDs for a fixed number of to be selected elements.
Note
Available state variables:
(States enabled by default are listed with +)
Cheap initialization.
Parameters: |
|
---|
Bases: mvpa.featsel.helpers.TailSelector
Given a sequence, provide Ids for a fraction of elements
Note
Available state variables:
(States enabled by default are listed with +)
Cheap initialization.
Parameters: |
|
---|
Bases: mvpa.featsel.helpers.StoppingCriterion
Stop computation if the latest error drops below a certain threshold.
Parameters: |
|
---|
Bases: mvpa.featsel.helpers.StoppingCriterion
Stop computation if for a number of steps error was increasing
Initialize with number of steps
Parameters: |
|
---|
Bases: mvpa.featsel.helpers.StoppingCriterion
Stop computation after a certain number of steps.
Initialize with number of steps.
Parameter: | steps (int) – Number of steps after which to stop. |
---|
Bases: mvpa.featsel.helpers.ElementSelector
Select elements based on specified range of values
Note
Available state variables:
(States enabled by default are listed with +)
Initialization RangeElementSelector
Parameters: |
|
---|
upper could be lower than lower – then selection is done on values <= lower or >=upper (ie tails). This would produce the same result if called with flipped values for mode and inclusive.
If no upper no lower is set, assuming upper,lower=0, thus outputing non-0 elements
Bases: object
Base class for all functors to decide when to stop RFE (or may be general optimization... so it probably will be moved out into some other module
Bases: mvpa.featsel.helpers.ElementSelector
Select elements from a tail of a distribution.
The default behaviour is to discard the lower tail of a given distribution.
Note
Available state variables:
(States enabled by default are listed with +)
Initialize TailSelector
