The fields of Evolutionary Computation (EC) and Machine Learning (ML) have always been tightly intertwined. At the metaphoric level, evolution can be viewed as learning and adapting at the species time scale, while ML acts at the individual scale. At the algorithmic level, both EC and ML fields somehow search for models to fit some available data. Supervised and unsupervised learning aims at fitting available data and generalizing well to unseen data, while reinforcement learning aims at maximizing some reward in a given context. Evolutionary Computation focuses on high-quality regions of a search space defined by a fitness function.
In this context, the incredible blossoming of ML in recent years, which has impacted all research domains, has particularly resonated in the EC community, opening new research opportunities in both fields. The use of ML techniques within EC algorithms, and meta-heuristics at large, is not new, but the tremendous recent progresses of ML have immediatly led to progresses in EC, from online hyperparameter adaptation to powerful surrogate modeling. On the other hand, beyond classical optimization techniques used in ML, there has always been some space for EC methods to successfully tackle problems out of reach of standard techniques, from minimizing non-differentiable losses to optimizing hyperparameters of ML pipelines and to searching rich unstructured search spaces, e.g., in Neural Architecture Search.
EvoLearn is particularly interested in, but not limited to, original theoretical and/or experimental works combining one way or another evolutionary computation and machine learning. Some examples are EC for fine-tuning of ML models, hyperparameter optimization, LLMs prompt and pre-prompt optimization, eXplainable AI, neural architecture search, as well as ML and generative AI for metaheuristic algorithm selection and configuration, evolutionary variation operators or representations, surrogate modeling, or linkage learning. Beyond such recombination, EvoLearn also welcomes contributions to theory, methodology or application of EC from the point of view of learning at the population level.
