  text: "This paper introduces a methodology for inverse-modeling of yarn-level mechanics
    of cloth, based on the mechanical response of fabrics in the real world. We compiled
    a database from physical tests of several different knitted fabrics used in the
    textile industry. These data span different types of complex knit patterns, yarn
    compositions, and fabric finishes, and the results demonstrate diverse physical
    properties like stiffness, nonlinearity, and anisotropy.\r\n\r\nWe then develop
    a system for approximating these mechanical responses with yarn-level cloth simulation.
    To do so, we introduce an efficient pipeline for converting between fabric-level
    data and yarn-level simulation, including a novel swatch-level approximation for
    speeding up computation, and some small-but-necessary extensions to yarn-level
    models used in computer graphics. The dataset used for this paper can be found
    at http://mslab.es/projects/YarnLevelFabrics."

  text: "The complex yarn structure of knitted and woven fabrics gives rise to both
    a mechanical and\r\nvisual complexity. The small-scale interactions of yarns colliding
    with and pulling on each\r\nother result in drastically different large-scale
    stretching and bending behavior, introducing\r\nanisotropy, curling, and more.
    While simulating cloth as individual yarns can reproduce this\r\ncomplexity and
    match the quality of real fabric, it may be too computationally expensive for\r\nlarge
    fabrics. On the other hand, continuum-based approaches do not need to discretize
    the\r\ncloth at a stitch-level, but it is non-trivial to find a material model
    that would replicate the\r\nlarge-scale behavior of yarn fabrics, and they discard
    the intricate visual detail. In this thesis,\r\nwe discuss three methods to try
    and bridge the gap between small-scale and large-scale yarn\r\nmechanics using
    numerical homogenization: fitting a continuum model to periodic yarn simulations,
    adding mechanics-aware yarn detail onto thin-shell simulations, and quantitatively\r\nfitting
    yarn parameters to physical measurements of real fabric.\r\nTo start, we present
    a method for animating yarn-level cloth effects using a thin-shell solver.\r\nWe
    first use a large number of periodic yarn-level simulations to build a model of
    the potential\r\nenergy density of the cloth, and then use it to compute forces
    in a thin-shell simulator. The\r\nresulting simulations faithfully reproduce expected
    effects like the stiffening of woven fabrics\r\nand the highly deformable nature
    and anisotropy of knitted fabrics at a fraction of the cost of\r\nfull yarn-level
    simulation.\r\nWhile our thin-shell simulations are able to capture large-scale
    yarn mechanics, they lack\r\nthe rich visual detail of yarn-level simulations.
    Therefore, we propose a method to animate\r\nyarn-level cloth geometry on top
    of an underlying deforming mesh in a mechanics-aware\r\nfashion in real time.
    Using triangle strains to interpolate precomputed yarn geometry, we are\r\nable
    to reproduce effects such as knit loops tightening under stretching at negligible
    cost.\r\nFinally, we introduce a methodology for inverse-modeling of yarn-level
    mechanics of cloth,\r\nbased on the mechanical response of fabrics in the real
    world. We compile a database from\r\nphysical tests of several knitted fabrics
    used in the textile industry spanning diverse physical\r\nproperties like stiffness,
    nonlinearity, and anisotropy. We then develop a system for approximating these
    mechanical responses with yarn-level cloth simulation, using homogenized\r\nshell
    models to speed up computation and adding some small-but-necessary extensions
    to\r\nyarn-level models used in computer graphics.\r\n"

  text: Triangle mesh-based simulations are able to produce satisfying animations
    of knitted and woven cloth; however, they lack the rich geometric detail of yarn-level
    simulations. Naive texturing approaches do not consider yarn-level physics, while
    full yarn-level simulations may become prohibitively expensive for large garments.
    We propose a method to animate yarn-level cloth geometry on top of an underlying
    deforming mesh in a mechanics-aware fashion. Using triangle strains to interpolate
    precomputed yarn geometry, we are able to reproduce effects such as knit loops
    tightening under stretching. In combination with precomputed mesh animation or
    real-time mesh simulation, our method is able to animate yarn-level cloth in real-time
    at large scales.

  text: 'We present a method for animating yarn-level cloth effects using a thin-shell
    solver. We accomplish this through numerical homogenization: we first use a large
    number of yarn-level simulations to build a model of the potential energy density
    of the cloth, and then use this energy density function to compute forces in a
    thin shell simulator. We model several yarn-based materials, including both woven
    and knitted fabrics. Our model faithfully reproduces expected effects like the
    stiffness of woven fabrics, and the highly deformable nature and anisotropy of
    knitted fabrics. Our approach does not require any real-world experiments nor
    measurements; because the method is based entirely on simulations, it can generate
    entirely new material models quickly, without the need for testing apparatuses
    or human intervention. We provide data-driven models of several woven and knitted
    fabrics, which can be used for efficient simulation with an off-the-shelf cloth
    solver.'

  text: 'A major open problem on the road to artificial intelligence is the development
    of incrementally learning systems that learn about more and more concepts over
    time from a stream of data. In this work, we introduce a new training strategy,
    iCaRL, that allows learning in such a class-incremental way: only the training
    data for a small number of classes has to be present at the same time and new
    classes can be added progressively. iCaRL learns strong classifiers and a data
    representation simultaneously. This distinguishes it from earlier works that were
    fundamentally limited to fixed data representations and therefore incompatible
    with deep learning architectures. We show by experiments on CIFAR-100 and ImageNet
    ILSVRC 2012 data that iCaRL can learn many classes incrementally over a long period
    of time where other strategies quickly fail. '
