[0.4.0] -

In this release the entire core of tcpc was rewritten and a lot of the api was reimagened. This release also has no proper deprecation. This repo will the wild west until the 1.0 release

There are a multitude of changes, that I do not remember all. Here is the list of most important things:

  • A lot of the import paths have changed. It is likely that you need to update some imports

  • A new way to resolve the mutable default issue was introduced. It uses a explicit factory. To make that more clear, the name for mutable wrapper has changed from mdf -> cf or from default -> CloneFactory

  • The overall class API got a lot slimmer. A bunch of methods like get_attributes, are now functions that can be called with the class or instance as argument. Most methods were further renamed to represent there meaning in the context of tpcp. For example, get_attributes -> get_results

  • The new concept of Parameter Annotation was added. You can add type annotations with the types Parameter, HyperParameter, OptimizableParameter, or PureParameter to a class parameter to indicate its role for the algorithm. This is in particularly helpful for optimizable Pipelines and algorithms. Wrapper methods can then use these annotations to run implementation checks and optimizations. The only method that uses these at the momement is GridSearchCV. It now allows to set pure_parameters to True, which will collect the list of all attributes annotated with PureParameter and use this information for performance optimization. Before, you needed to specify the list of pure parameters manually.

  • Some core classes where renamed: BaseAlgorithm -> Algorithm, SimplePipeline -> Pipeline

  • The decorators to make run and self_optimize safe are now reimagened and renamed to make_run_safe and make_optimize_safe
