Sozialwissenschaftliche Konflikttheorienhe high-dimensional data space in latent space. The variants reach from sorting approaches in 1-dimensional latent spaces to submanifold learning in continuous latent spaces with separate parameterizations for each model. In the following, we summarize the most important results of this work.

Introduction,raphs like breadth-first and depth-first search to advanced reinforcement strategies for learning of complex behaviors in uncertain environments. Many AI research objectives aim at the solution of special problem classes. Subareas like speech processing have shown impressive achievements in recent years that come close to human abilities.

Dimensionality Reductionings. Dimensionality reduction can be employed for various tasks, e.g., visualization, preprocessing for pattern recognition methods, or for symbolic algorithms. To allow human understanding and interpretation of high-dimensional data, the reduction to 2- and 3-dimensional spaces is an important task.

Metaheuristicsl embedding. We compare a discrete evolutionary approach based on stochastic swaps to a continuous evolutionary variant that is based on evolution strategies, i.e., the covariance matrix adaptation variant CMA-ES. The continuous variant is the first step to embeddings into continuous latent spaces.
