Workflow
type: NamedIndividual
type: Concept
definition: The process that is used to produce a specific research result in a concrete domain. A workflow comprises a series of components that are arranged in a directed graph to set the order of execution of such components.

Regularization parameter C
type: Concept
definition: It is a hyperparameter of the Support Vector Machine. This hyperparameter trades off a wide margin against classification errors. High C produces weak regularisation, resulting in a 'harder' margin, fewer training errors and a higher risk of overfitting. Low C produces stronger regularisation, resulting in a 'softer' margin that tolerates training errors and is typically more robust in terms of generalisation.
