class mvpa2.mappers.prototype.PrototypeMapper(similarities, prototypes=None, **kwargs)

Mapper to project data onto a space defined by prototypes from the same space via a similarity function.

Notes

Available conditional attributes:

• calling_time+: Time (in seconds) it took to call the node
• raw_results: Computed results before invoking postproc. Stored only if postproc is not None.
• training_time+: Time (in seconds) it took to train the learner

(Conditional attributes enabled by default suffixed with +)

Parameters :

similarities : list

A list of similarity functions.

prototypes : Dataset or list

A dataset or a list of instances (e.g., streamlines)?

enable_ca : None or list of str

Names of the conditional attributes which should be enabled in addition to the default ones

disable_ca : None or list of str

Names of the conditional attributes which should be disabled

demean : bool
