  text: 'Classic automated algorithm selection (AS) for (combinatorial) optimization
    problems heavily relies on so-called instance features, i.e., numerical characteristics
    of the problem at hand ideally extracted with computationally low-demanding routines.
    For the traveling salesperson problem (TSP) a plethora of features have been suggested.
    Most of these features are, if at all, only normalized imprecisely raising the
    issue of feature values being strongly affected by the instance size. Such artifacts
    may have detrimental effects on algorithm selection models. We propose a normalization
    for two feature groups which stood out in multiple AS studies on the TSP: (a)
    features based on a minimum spanning tree (MST) and (b) nearest neighbor relationships
    of the input instance. To this end we theoretically derive minimum and maximum
    values for properties of MSTs and k-nearest neighbor graphs (NNG) of Euclidean
    graphs. We analyze the differences in feature space between normalized versions
    of these features and their unnormalized counterparts. Our empirical investigations
    on various TSP benchmark sets point out that the feature scaling succeeds in eliminating
    the effect of the instance size. A proof-of-concept AS-study shows promising results:
    models trained with normalized features tend to outperform those trained with
    the respective vanilla features.'

  text: 'Automated Algorithm Configuration (AAC) usually takes a global perspective:
    it identifies a parameter configuration for an (optimization) algorithm that maximizes
    a performance metric over a set of instances. However, the optimal choice of parameters
    strongly depends on the instance at hand and should thus be calculated on a per-instance
    basis. We explore the potential of Per-Instance Algorithm Configuration (PIAC)
    by using Reinforcement Learning (RL). To this end, we propose a novel PIAC approach
    that is based on deep neural networks. We apply it to predict configurations for
    the Lin\textendash Kernighan heuristic (LKH) for the Traveling Salesperson Problem
    (TSP) individually for every single instance. To train our PIAC approach, we create
    a large set of 100000 TSP instances with 2000 nodes each \textemdash currently
    the largest benchmark set to the best of our knowledge. We compare our approach
    to the state-of-the-art AAC method Sequential Model-based Algorithm Configuration
    (SMAC). The results show that our PIAC approach outperforms this baseline on both
    the newly created instance set and established instance sets.'

  text: Exploratory Landscape Analysis is a powerful technique for numerically characterizing
    landscapes of single-objective continuous optimization problems. Landscape insights
    are crucial both for problem understanding as well as for assessing benchmark
    set diversity and composition. Despite the irrefutable usefulness of these features,
    they suffer from their own ailments and downsides. Hence, in this work we provide
    a collection of different approaches to characterize optimization landscapes.
    Similar to conventional landscape features, we require a small initial sample.
    However, instead of computing features based on that sample, we develop alternative
    representations of the original sample. These range from point clouds to 2D images
    and, therefore, are entirely feature-free. We demonstrate and validate our devised
    methods on the BBOB testbed and predict, with the help of Deep Learning, the high-level,
    expert-based landscape properties such as the degree of multimodality and the
    existence of funnel structures. The quality of our approaches is on par with methods
    relying on the traditional landscape features. Thereby, we provide an exciting
    new perspective on every research area which utilizes problem information such
    as problem understanding and algorithm design as well as automated algorithm configuration
    and selection.

  text: In recent years, feature-based automated algorithm selection using exploratory
    landscape analysis has demonstrated its great potential in single-objective continuous
    black-box optimization. However, feature computation is problem-specific and can
    be costly in terms of computational resources. This paper investigates feature-free
    approaches that rely on state-of-the-art deep learning techniques operating on
    either images or point clouds. We show that point-cloud-based strategies, in particular,
    are highly competitive and also substantially reduce the size of the required
    solver portfolio. Moreover, we highlight the effect and importance of cost-sensitive
    learning in automated algorithm selection models.

  text: Social media platforms are essential for information sharing and, thus, prone
    to coordinated dis- and misinformation campaigns. Nevertheless, research in this
    area is hampered by strict data sharing regulations imposed by the platforms,
    resulting in a lack of benchmark data. Previous work focused on circumventing
    these rules by either pseudonymizing the data or sharing fragments. In this work,
    we will address the benchmarking crisis by presenting a methodology that can be
    used to create artificial campaigns out of original campaign building blocks.
    We conduct a proof-of-concept study using the freely available generative language
    model GPT-Neo in this context and demonstrate that the campaign patterns can flexibly
    be adapted to an underlying social media stream and evade state-of-the-art campaign
    detection approaches based on stream clustering. Thus, we not only provide a framework
    for artificial benchmark generation but also demonstrate the possible adversarial
    nature of such benchmarks for challenging and advancing current campaign detection
    methods.

  text: We propose a novel method for automated algorithm selection in the domain
    of single-objective continuous black-box optimization. In contrast to existing
    methods, we use convolutional neural networks as the selection apparatus which
    bases its decision on a so-called ‘fitness map’. This fitness map is a 2D representation
    of a two dimensional search space where different gray scales indicate the quality
    of found solutions in certain areas. Our devised approach uses a modular CMA-ES
    framework which offers the option to create the conventional CMA-ES, CMA-ES with
    the alternate step-size adaptation and many other variants proposed over the years.
    In total, 4 608 different configurations are possible where most configurations
    are of complementary nature. In this proof-of-concept work, we consider a subset
    of 32 possible configurations. The developed method is evaluated against an excerpt
    of BBOB functions and its performance is compared against baselines that are commonly
    used in automated algorithm selection - the best standalone algorithm (configuration)
    and the best obtainable sequence of configurations. While the results indicate
    that the use of the fitness map is not superior on every benchmark problem, it
    indubitably shows its merit on more hard-to-solve problems. This offers a promising
    perspective for generalizing to other types of optimization problems and problem
    domains.

  text: Abuse and hate are penetrating social media and many comment sections of news
    media companies. These platform providers invest considerable efforts to mod-
    erate user-generated contributions to prevent losing readers who get appalled
    by inappropriate texts. This is further enforced by legislative actions, which
    make non-clearance of these comments a punishable action. While (semi-)automated
    solutions using Natural Language Processing and advanced Machine Learning techniques
    are getting increasingly sophisticated, the domain of abusive language detection
    still struggles as large non-English and well-curated datasets are scarce or not
    publicly available. With this work, we publish and analyse the largest annotated
    German abusive language comment datasets to date. In contrast to existing datasets,
    we achieve a high labelling standard by conducting a thorough crowd-based an-
    notation study that complements professional moderators’ decisions, which are
    also included in the dataset. We compare and cross-evaluate the performance of
    baseline algorithms and state-of-the-art transformer-based language models, which
    are fine-tuned on our datasets and an existing alternative, showing the usefulness
    for the community.

  text: 'Classic automated algorithm selection (AS) for (combinatorial) optimization
    problems heavily relies on so-called instance features, i.e., numerical characteristics
    of the problem at hand ideally extracted with computationally low-demanding routines.
    For the traveling salesperson problem (TSP) a plethora of features have been suggested.
    Most of these features are, if at all, only normalized imprecisely raising the
    issue of feature values being strongly affected by the instance size. Such artifacts
    may have detrimental effects on algorithm selection models. We propose a normalization
    for two feature groups which stood out in multiple AS studies on the TSP: (a)
    features based on a minimum spanning tree (MST) and (b) a k-nearest neighbor graph
    (NNG) transformation of the input instance. To this end we theoretically derive
    minimum and maximum values for properties of MSTs and k-NNGs of Euclidean graphs.
    We analyze the differences in feature space between normalized versions of these
    features and their unnormalized counterparts. Our empirical investigations on
    various TSP benchmark sets point out that the feature scaling succeeds in eliminating
    the effect of the instance size. Eventually, a proof-of-concept AS-study shows
    promising results: models trained with normalized features tend to outperform
    those trained with the respective vanilla features.'

  text: Artificial neural networks in general and deep learning networks in particular
    established themselves as popular and powerful machine learning algorithms. While
    the often tremendous sizes of these networks are beneficial when solving complex
    tasks, the tremendous number of parameters also causes such networks to be vulnerable
    to malicious behavior such as adversarial perturbations. These perturbations can
    change a model's classification decision. Moreover, while single-step adversaries
    can easily be transferred from network to network, the transfer of more powerful
    multi-step adversaries has - usually - been rather difficult.In this work, we
    introduce a method for generating strong adversaries that can easily (and frequently)
    be transferred between different models. This method is then used to generate
    a large set of adversaries, based on which the effects of selected defense methods
    are experimentally assessed. At last, we introduce a novel, simple, yet effective
    approach to enhance the resilience of neural networks against adversaries and
    benchmark it against established defense methods. In contrast to the already existing
    methods, our proposed defense approach is much more efficient as it only requires
    a single additional forward-pass to achieve comparable performance results.

  text: 'In this work we focus on the well-known Euclidean Traveling Salesperson Problem
    (TSP) and two highly competitive inexact heuristic TSP solvers, EAX and LKH, in
    the context of per-instance algorithm selection (AS). We evolve instances with
    1000 nodes where the solvers show strongly different performance profiles. These
    instances serve as a basis for an exploratory study on the identification of well-discriminating
    problem characteristics (features). Our results in a nutshell: we show that even
    though (1) promising features exist, (2) these are in line with previous results
    from the literature, and (3) models trained with these features are more accurate
    than models adopting sophisticated feature selection methods, the advantage is
    not close to the virtual best solver in terms of penalized average runtime and
    so is the performance gain over the single best solver. However, we show that
    a feature-free deep neural network based approach solely based on visual representation
    of the instances already matches classical AS model results and thus shows huge
    potential for future studies.'
