Title: EFECTIVE - Evolutionary Framework for Classifier Assessment and Improvement
Abstract:
Typical Machine Learning approaches rely on a dataset and a model to solve problems. For most problems, optimisation of Machine Learning approaches is crucial to attaining competitive performances. Most of the effort goes toward optimising the model by exploring new algorithms and tuning the parameters. Nevertheless, the dataset is also a key part for Machine Learning performance. Gathering, constructing and optimising a representative dataset is a hard task and a time-consuming endeavour, with no well-established guidelines to follow. The Evolutionary Framework for Classifier Assessment and Improvement is introduced and explored. The key parts of the framework are the following: the Classifier System module, which holds the Machine Learning model that is going to be assessed and improved; the Evolutionary Computation module responsible for generating the new instances using the Classifier System module for fitness.
