Our Computational Intelligence Research Group

 

A. What is Computational Intelligence (CI)?

CI deals with bio-inspired computational methods. Its roots are in Cybernetics (http://www.asc-cybernetics.org/foundations/definitions.htm ) and Soft-computing (https://en.wikipedia.org/wiki/Soft_computing).

While soft computing has focused on Artificial Neural Networks (ANNs), Fuzzy Logic (FL), and Evolutionary Computation (EC), CI has a much wider scope. In addition to the above three building blocks, CI deals with other bio-inspired methods such as Swarm Intelligence and Artificial Immune Systems. CI encompasses not only such bio-inspired computational techniques, but also their hybridizations.

Although developed somewhat separately from Artificial Intelligence (AI), CI may be considered as a branch of AI.

CI methods are currently in use in many technical systems and are consistently explored by researchers all over the world. Such activities are in the focus of the IEEE Society of Computational Intelligence.

CI applicability to robotics and engineering design makes it a valid topic for teaching mechanical engineering students. Such a course is provided by our school for both undergraduate and graduate students.

 

B. Overview on our Research

Our research group focuses on Evolutionary Computation (EC) methods. It also concerns their hybridization with Artificial Neural-Networks. Such hybridization is commonly termed Neuroevolution or Evolutionary Neural-Networks.

Concerning EC, we develop generic methods and algorithms with a focus on multi-objective problems. Such problems are common in engineering and other application areas (See https://en.wikipedia.org/wiki/Multi-objective_optimization ). Clearly, in the design of technical systems one must face with tradeoffs that are imposed by the existence of conflicting design objectives. Evolutionary algorithms are known to be most useful for finding the Pareto-optimal solutions to such problems. Such a solution approach, to multi-objective problems, reveals the performance tradeoffs, which supports a rational selection of a solution.

In 2014 we have extended our interest in multi-objective optimization to the related problem of competitive multi-objective games (see more at subsection C.2 below).

Although not focusing on neuro-fuzzy methods, since 2014 we have started to get interested in such an approach (See more at subsection C.3 below).

 

Work-in-progress & Reports

 

C. Uniqueness of our Research

1.     The Concept-based Search and Optimization Approach: Traditional optimization aims at finding optimal solutions. In contrast, the concept-based search and optimization approach aims to support the selection of conceptual solutions. Its development has been strongly connected with Pareto-based multi-objective optimization and multi-criteria decision-making.

For over a decade we have been leading the development of the concept-based approach. We have uniquely developed a relaxed-Pareto version of the concept-based approach. It was motivated by the need to overcome the logical flaw that we have found in the original s-Pareto version of the concept-based approach (see explanation in Moshaiov et al. 2015 [6]).

Our relaxed-Pareto version of the concept-based approach can be used not only for concept selection, but also for the exploration of design spaces, both at the conceptual and particular design levels (Moshaiov et al. 2015 [6]).

In collaboration with Dr. Ohad Gur of the Israel Aerospace Industries, we have demonstrated the practicality of our concept-based approach to the industry.

2.     Competitive Multi-objective Games:In collaboration with Dr Gideon Avigad, a former PhD student of our group, and others, we have developed a unique non-utility approach to multi-objective games, which are also known as multi-payoff games (Eisenstadt et al. 2016 pdf). At present we are investigating the capability of our non-utility approach to support decision-makers in various application areas such as defence (e.g., cyber security) and operation research.

3.     Neuro-fuzzy Learning of the Behavior of Biological Systems: In collaboration with Prof. Amir Ayali, we have developed a neuro-fuzzy approach that can uniquely support the understanding of biological systems (Segal et al. 2016 [3]).

4.     Family Bootstrapping: Commonly, evolutionary computation process is initiated with a random population of solutions. Yet, for complex problems, such an approach may fail to get started without taking proper measures. This phenomenon is known as the bootstrap problem. To overcome the problem, we have suggested a genetic transfer learning approach, which we have termed family bootstrapping (Moshaiov and Tal 2014 [9]).

While other methods exist to cope with the bootstrap problem, our unique family bootstrapping approach may facilitate revolutionizing the evolutionary design of robots. This is due to the use of relations among tasks. Family bootstrapping may lead to the creation of databases of useful ancestries, which will eliminate, or at least reduce, the need to initiate evolution processes from random.

5.     Multi-objective Neuroevolution: We have been one of the first groups to consider the application of evolutionary multi-objective optimization for neuroevolution, and in particular for robot neuro-controllers. With this respect, we have been the first to propose an algorithm for multi-objective evolution of CPNs, i.e., counterpropagation networks (Moshaiov and Zadok 2013 [14]). We have also developed a unique MO-TWEANN, i.e., Multi-Objective version of the famous NEAT algorithm, for Topology and Weight Evolving Artificial Neural Network (Abramovich and Moshaiov 2016 [1]).

6.     Multi-Competence Cybernetics: We have been the first to postulate on the significance of Pareto-optimality to the study of biological systems (Moshaiov 2008 [pdf]). A few years passed and in 2012 researchers from the Weizmann Institute of Science published a paper in Science confirming our suggestion J. (See Shoval et al., Science 336, 1157, 2012).
