Release Notes#

v1.1.0 April 10, 2024#

Changes:
- The functions parameter in the GeneticFeatureSynthesis class now accepts a list of strings representing the names of the functions to be used in the genetic programming process. The default value is [‘add’, ‘sub’, ‘mul’, ‘div’, ‘square’, ‘cube’, ‘abs’ ‘negate’, ‘sin’, ‘cos’, ‘tan’]. The full list of built in functions can be found in the list_operations function.
- Added SymbolicMulConstant and SymbolicAddConstant symbolic functions. These can be useful where their is an offset to the data but are not currently used by default as there is a risk of overfitting where an offset is not present.
- Renamed list_operations to list_symbolic_functions for consistency
- Added CustomSymbolicFunction class to allow users to define their own symbolic functions to be used in the genetic feature synthesis process.
- Updated unit tests to reflect changes
Documentation:
- Added example showing use of custom symbolic functions.

Changes:
- Added tournament_size parameter to GeneticFeatureSelection class and set default to 10
- Set default tournament size to 10 for GeneticFeatureSynthesis class
Documentation:
- Updated README.md example
- Updated example notebooks
- Added eplanation of tournament selection in the Tuning the Genetic Feature Synthesis guide
