Evolutionary Computation in Practice
In the Evolutionary Computation in Practice (ECiP) track, well-known speakers with outstanding reputation in academia and industry present background and insider information on how to establish reliable cooperation with industrial partners. They actually run companies or are involved in cooperation between academia and industry.
If you attend, you will learn multiple ways to extend EC practice beyond the approaches found in textbooks. Experts in real-world optimization with decades of experience share their approaches to creating successful projects for real-world clients. Some of what they do is based on sound project management principles, and some is specific to our type of optimization projects. If you are working in academia and are interested in managing industrial projects, you will receive valuable hints for your own research projects.
In 2023, ECiP will be a hybrid event. We will do our best to enable opportunities for establishing contacts among participants.

Evolutionary optimization + Knowledge discovery: A practical combination for intelligent decision support
The fields of EMO (Evolutionary Multi-objective Optimization) and MCDM (Multi-Criteria Decision Making) play complementary roles in finding a practical solution to real-world optimization problems which often involve multiple conflicting objectives. While much of the EMO research focuses on obtaining a good representation of trade-off solutions, MCDM methods are mainly aimed at incorporating decision-maker’s preferences in the objective space to identify a single solution for implementation. Naturally, several methods for visualizing the objective function values have been developed to support the task of decision-making, while the variable space has largely been ignored in this regard. However, it can be argued that in many practical problems, knowledge about the impact of variables on the objective space will better inform the decision-maker about their preferences, leading to higher confidence and quality in decisions. It is possible to obtain such knowledge from EMO solutions by customizing various data mining and machine learning methods to take preferences into account. Such a combination of knowledge discovery with EMO methods, together with established visualization and preference elicitation techniques, can lay the foundation for intelligent decision support. This talk will first introduce knowledge discovery in the context of multi-objective optimization, along with relevant forms of explicit knowledge and available methods to extract them from solution sets. This will be followed by a brief demonstration of Mimer – a recently developed intelligent decision support tool for interactive knowledge discovery and knowledge visualization.

Surrogate-based evolutionary algorithms in the optimization of deep learning for semantic segmentation
Evolutionary computation has constantly been a first choice for the optimization of the hyperparameters of models in order to enhance their performance for real-world scenarios. With the advent of deep learning and its extensive number of hyperparameters, evolutionary algorithms found a new large playground. However, since the training of a deep learning model is highly resource-consuming, the repetition of the process in order to evaluate every resulting potential solution is not feasible. Surrogate-based evolutionary optimization has in this sense proven to be an efficient solution, with various machine learning approaches offering a partial model of the original deep learner that could be used for the fitness evaluation of its potential hyperparameter configurations. This talk will present a practical example of the potential of surrogate-based evolutionary optimization for tuning non-architectural deep learning hyperparameters, i.e., corresponding weights in an imbalanced classification real-world task of semantic segmentation of corrosion compounds from microscopy images of archaeological objects.

IMProvT II – Intelligent measurement methods for the energetic process optimization of drinking water supply and distribution
The goal of the “IMProvT II” project (Intelligent Measurement Methods for Process Optimization of Drinking Water Provision and Distribution) is to develop a digitalization platform for the water industry to optimize the energy efficiency of drinking water provision and distribution. The project aims to address the high variable costs, which account for the largest share of energy costs in the overall expenses of water supply. Rising energy prices have led to a significant increase in water supply fees, creating a burden for consumers. Therefore, ensuring an energy-efficient operation of water supply systems is crucial. To achieve this, a central and flexible data platform is needed to integrate relevant process and management information from water extraction and distribution networks. By consolidating this data, it can be made available to other services for analysis and operational optimization. The platform will utilize methods of Artificial Intelligence (AI) and Machine Learning (ML) to analyze, predict, optimize, and control various aspects of the water supply system. The project also focuses on data privacy and security, especially for Critical Infrastructures (KRITIS), and ensures that the digitalization platform does not directly interfere with the control system. Instead, it acts as a parallel assistant system. Additionally, the project aims to design and analyze business models for digitalization in the water industry to facilitate knowledge transfer between research, water associations, and the industry. The project includes a case study involving two waterworks to demonstrate the potential energy savings and financial benefits. The developed solution can potentially reduce the energy consumption of water provision by 11-14%, resulting in significant cost savings. Furthermore, this reduction in energy demand would lead to a corresponding decrease in CO2 emissions. The project aligns with the maturity model for digitalization in the water industry and focuses on advancing stages 4, 5, and 6, which involve understanding the system, forecasting, and achieving autonomous control through adaptive regulation and assistance systems.

Sideslip angle estimation with transfer learning capabilities: A deep learning approach for motorsports
Knowing the sideslip angle of a race car at every point in time is a crucial requirement to compete in modern day competitions. Unfortunately, measuring the sideslip angle directly is prohibited under the regulations in endurance racing and too expensive to be deployed in mass-produced cars. Being limited by the available data and capabilities of embedded hardware, how can one get a good estimate of the sideslip angle?
Considering the inherent non-linear behavior of vehicle dynamics, neural network approaches have gained popularity, particularly in high-speed environments. However, these approaches often struggle to generalize effectively across different car setups and tracks. Our research focuses on the transfer of knowledge from one track to others, where labeled data is sparse or even not available. By doing so, the findings could have the potential to enhance performance not only in motorsports, but also in the long term for electric cars, where more complex control strategies are possible.
Attendees will have the opportunity to gain insights into the practical implications of our research and its potential to improve virtual sensing in the literally most fast paced environment.
