PyOperators 0.5
What’s new ?
- New operators: ReductionOperator, SumOperator, ProductOperator, MinOperator, MaxOperator, MinMaxOperator.
- New operator IntegrationTrapezeWeightOperator.
- New composite operator GroupOperator: same as CompositionOperator, but without the associativity rules.
- New C-ufuncs, used in SoftThresholdingOperator and HardThresholdingOperator.
- Improved asoperator: handle callable, ufunc, matrices, scalars, add ‘constant’ keyword to tell whether scalars should be translated into HomothetyOperator or ConstantOperator.
- RoundOperator: add methods ‘rhtmi’ (round half to minus infinity), ‘rhtpi’ (round half to plus infinity).
- Make todense method work with uncontrained output shape operators.
- Set dtype to None for DiagonalOperators with only 1 and 0 on the diagonal.
- Set ‘square’ flag automatically for ufuncs. Infer ‘real’ flag from ufunc’s types.
- Fix flags shape_input, shape_output in CommutativeCompositeOperator and CompositionOperator.
- Add ‘idempotent’ flag to RoundOperator and HardThresholdingOperator.
Under the hood:
- Make composite operators behave like regular Operators (in terms of attribute handling and merging) to enable subclassing them.
- Implement CompositionOperator and CommutativeCompositeOperator associativity through binary rules.
- Add helper routine find in utils.
- Add skiptest decorator.
- Speed up all_eq helper routine.
