mvpa2.clfs.gpr.GPRLinearWeights

Inheritance diagram of GPRLinearWeights

class mvpa2.clfs.gpr.GPRLinearWeights(clf, force_train=True, **kwargs)

SensitivityAnalyzer that reports the weights GPR trained on a given Dataset.

In case of LinearKernel compute explicitly the coefficients of the linear regression, together with their variances (if requested).

Note that the intercept is not computed.

Notes

Available conditional attributes:

  • calling_time+: Time (in seconds) it took to call the node
  • null_prob+: None
  • null_t: None
  • 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
  • variances: Variances of the weights (for GeneralizedLinearKernel)

(Conditional attributes enabled by default suffixed with +)

Initialize the analyzer with the classifier it shall use.

Parameters :

clf : Classifier

classifier to use.

force_train : bool

Flag whether the learner will enforce training on the input dataset upon every call.

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

null_dist : instance of distribution estimator

The estimated distribution is used to assign a probability for a certain value of the computed measure.

auto_train : bool

Flag whether the learner will automatically train itself on the input dataset when called untrained.

space: str, optional :

Name of the ‘processing space’. The actual meaning of this argument heavily depends on the sub-class implementation. In general, this is a trigger that tells the node to compute and store information about the input data that is “interesting” in the context of the corresponding processing in the output dataset.

postproc : Node instance, optional

Node to perform post-processing of results. This node is applied in __call__() to perform a final processing step on the to be result dataset. If None, nothing is done.

descr : str

Description of the instance
