Special Issue Information

Dear Colleagues,

Evolutionary computation (EC), a family of algorithms inspired by biological evolution for global optimization, has been developed for a few decades. Potential applications are wide-ranging and include problems from combinatorial optimization, multi-objective optimization, and numerical optimization in diverse domains, such as engineering, biology, medicine, robotics, etc. Machine learning (ML) is one of the most engaging research and application areas within computer science today. Its ability to find patterns, clusters, and hidden knowledge from data has allowed us to understand, model, and predict the behaviors of complex systems.

Nowadays, symmetry and asymmetry play important roles in various aspects of EC and ML. These concepts can be applied to algorithm design, problem representation, and solution optimization. Usually, the concept of a fitness landscape in EC assumes a certain level of symmetry where similar solutions have similar fitness values. This symmetry can help in navigating the search space more efficiently. Also, symmetry/asymmetry is critical in ML, particularly in the design of algorithms and the interpretation of data. For example, the structure of many neural networks assumes symmetry in the weights and biases.

This Special Issue aims to explore the current impact, advances, and applications of symmetry/asymmetry in EC and ML. For either EC or ML, understanding and exploiting symmetry can lead to more efficient algorithms, while recognizing and addressing asymmetry is crucial for the robustness and generalization of algorithms or models. Researchers and practitioners must be aware of these properties when designing algorithms and interpreting results. Moreover, it is interesting to combine ML and EMO ideas in a single coherent framework. EC is very helpful to solve complex ML problems, e.g., when the fitness function of the ML model has many local extremes that can trap sequential methods. Meanwhile, ML methods can be used to analyze EC population data to better understand the problem structure, to understand what makes the solutions optimal, and to create new and often superior solutions.

We invite submissions on recent advances in the theory and applications of evolutionary computation and machine learning that explore the role of symmetry and asymmetry.

Session-based recommendation (SBR) aims to predict a user’s next item of interest by analyzing their anonymous browsing patterns. While previous studies have demonstrated considerable efficacy, they may fall short when confronted with exceedingly sparse interaction data. This paper presents a novel approach, cross-session graph and hypergraph co-guided session-based recommendation (CGH-SBR), which adeptly forecasts subsequent items while upholding efficiency and precision. First, we construct a directed graph that captures sequential dependencies by modeling cross-session item transitions, alongside building a hypergraph that encapsulates higher-order relationships between items within sessions. Subsequently, we employ two distinct graph neural networks (GNNs) to learn item representations on these two graphs separately. Further, we innovate by integrating a symmetry-aware co-guided learning framework. This framework promotes the integration of diverse perspectives and facilitates mutual learning, leveraging the data’s symmetric properties to enhance the model’s pattern recognition capabilities. Comprehensive experimentation conducted on two public datasets showcases the outstanding performance and potential of the recommendation system presented by CGH-SBR. Full article
