Module gradient

source code

The :mod:`parsimony.algorithms.gradient` module includes several algorithms that minimises an explicit loss function while utilising the gradient of the function.

Algorithms may not store states. I.e., if they are classes, do not keep references to objects with state in the algorithm objects. It should be possible to copy and share algorithms between e.g. estimators, and thus they should not depend on any state.
