Iron Hack - A symposium/hackathon focused on porphyrias, Friedreich's ataxia, and other rare iron-related diseases.
Background: Basic and clinical scientific research at the University of South Florida (USF) have intersected to support a multi-faceted approach around a common focus on rare iron-related diseases. We proposed a modified version of the National Center for Biotechnology Information's (NCBI) Hackathon-model to take full advantage of local expertise in building "Iron Hack", a rare disease-focused hackathon. As the collaborative, problem-solving nature of hackathons tends to attract participants of highly-diverse backgrounds, organizers facilitated a symposium on rare iron-related diseases, specifically porphyrias and Friedreich's ataxia, pitched at general audiences. Methods: The hackathon was structured to begin each day with presentations by expert clinicians, genetic counselors, researchers focused on molecular and cellular biology, public health/global health, genetics/genomics, computational biology, bioinformatics, biomolecular science, bioengineering, and computer science, as well as guest speakers from the American Porphyria Foundation (APF) and Friedreich's Ataxia Research Alliance (FARA) to inform participants as to the human impact of these diseases. Results: As a result of this hackathon, we developed resources that are relevant not only to these specific disease-models, but also to other rare diseases and general bioinformatics problems. Within two and a half days, "Iron Hack" participants successfully built collaborative projects to visualize data, build databases, improve rare disease diagnosis, and study rare-disease inheritance. Conclusions: The purpose of this manuscript is to demonstrate the utility of a hackathon model to generate prototypes of generalizable tools for a given disease and train clinicians and data scientists to interact more effectively
Interactive Fitness Domains in Competitive Coevolutionary Algorithm
Evolutionary Algorithms (EA) have been successfully applied to a wide range of optimization and search problems where no mathematical model of the quality of a candidate solution is available. Interactive Evolutionary Algorithms (IEA) and Competitive Coevolutionary Algorithms (CCoEA) go one step further by being able to tackle problems where the only means to evaluate the quality of a candidate solution is via interactions. In a typical IEA, interactions take place between the solution being evolved and human evaluators. In a CCoEA, interactions take place between solutions themselves, without need for human interaction. This dissertation identifies computer-aided learning as an application domain that exemplifies the overlap of both fields. In particular, this work first develops a novel interactive and competitive (co)evolutionary approach to evolve candidate solutions. To do so, we identify viable algorithms, analyze them and author new variants of hill climber algorithms. Then, we design and implement a competitive coevolutionary interaction-based algorithm. The performance of the resulting heuristic is evaluated with respect to its ability to approximate a full Coevolutionary Dimension Extraction (CDE) process. This allows us to ensure that the proposed approach evolves candidate solutions that have pedagogically relevant in an educational application. However, the underlying hill climber algorithm produces some candidate solutions that exhibit the same interaction outcomes against opponent solutions. So, we also propose different approaches to improve the diversity of the solutions being evolved. To this end, we relax the strict acceptance condition in existing hill climbing algorithms relying on Pareto dominance. The proposed variant draw its inspiration from the Non-dominated Sorted Genetic Algorithm (NSGA), commonly used in evolutionary multixobjectives optimization. We also introduce selection methods based on competitive shared fitness, and the analysis of the interaction space among solutions. Finally, we study Pareto dominance relations of coevolutionary interactions by looking at the interaction matrix of both coevolutionary benchmarks and our educational application. This results in a unique perspective to understanding both structural and relational dominance in coevolutionary interactions. This method can be applied in any open-ended problems where the quality of solutions can not be defined mathematically. It reveals the applicability of CDE, its sensitivity to dominance relations, and its robustness to noisy outcomes
