  text: 'Automated machine learning (AutoML) supports the algorithmic construction
    and data-specific customization of machine learning pipelines, including the selection,
    combination, and parametrization of machine learning algorithms as main constituents.
    Generally speaking, AutoML approaches comprise two major components: a search
    space model and an optimizer for traversing the space. Recent approaches have
    shown impressive results in the realm of supervised learning, most notably (single-label)
    classification (SLC). Moreover, first attempts at extending these approaches towards
    multi-label classification (MLC) have been made. While the space of candidate
    pipelines is already huge in SLC, the complexity of the search space is raised
    to an even higher power in MLC. One may wonder, therefore, whether and to what
    extent optimizers established for SLC can scale to this increased complexity,
    and how they compare to each other. This paper makes the following contributions:
    First, we survey existing approaches to AutoML for MLC. Second, we augment these
    approaches with optimizers not previously tried for MLC. Third, we propose a benchmarking
    framework that supports a fair and systematic comparison. Fourth, we conduct an
    extensive experimental study, evaluating the methods on a suite of MLC problems.
    We find a grammar-based best-first search to compare favorably to other optimizers.'

  text: "In automated machine learning (AutoML), the process of engineering machine
    learning applications with respect to a specific problem is (partially) automated.\r\nVarious
    AutoML tools have already been introduced to provide out-of-the-box machine learning
    functionality.\r\nMore specifically, by selecting machine learning algorithms
    and optimizing their hyperparameters, these tools produce a machine learning pipeline
    tailored to the problem at hand.\r\nExcept for TPOT, all of these tools restrict
    the maximum number of processing steps of such a pipeline.\r\nHowever, as TPOT
    follows an evolutionary approach, it suffers from performance issues when dealing
    with larger datasets.\r\nIn this paper, we present an alternative approach leveraging
    a hierarchical planning to configure machine learning pipelines that are unlimited
    in length.\r\nWe evaluate our approach and find its performance to be competitive
    with other AutoML tools, including TPOT."
