  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: "Metazoan development relies on the formation and remodeling of cell-cell
    contacts. The \r\nbinding of adhesion receptors and remodeling of the actomyosin
    cell cortex at cell-cell \r\ninteraction sites have been implicated in cell-cell
    contact formation. Yet, how these two \r\nprocesses functionally interact to drive
    cell-cell contact expansion and strengthening \r\nremains unclear. Here, we study
    how primary germ layer progenitor cells from zebrafish \r\nbind to supported lipid
    bilayers (SLB) functionalized with E-cadherin ectodomains as an \r\nassay system
    for monitoring cell-cell contact formation at high spatiotemporal resolution.
    \r\nWe show that cell-cell contact formation represents a two-tiered process:
    E-cadherin\x02mediated downregulation of the small GTPase RhoA at the forming
    contact leads to both \r\ndepletion of Myosin-2 and decrease of F-actin. This
    is followed by centrifugal actin \r\nnetwork flows at the contact triggered by
    a sharp gradient of Myosin-2 at the rim of the \r\ncontact zone, with Myosin-2
    displaying higher cortical localization outside than inside of \r\nthe contact.
    These centrifugal cortical actin flows, in turn, not only further dilute the actin
    \r\nnetwork at the contact disc, but also lead to an accumulation of both F-actin
    and E\x02cadherin at the contact rim. Eventually, this combination of actomyosin
    downregulation \r\nand flows at the contact contribute to the characteristic molecular
    organization implicated \r\nin contact formation and maintenance: depletion of
    cortical actomyosin at the contact disc, \r\ndriving contact expansion by lowering
    interfacial tension at the contact, and accumulation \r\nof both E-cadherin and
    F-actin at the contact rim, mechanically linking the contractile \r\ncortices
    of the adhering cells. Thus, using a biomimetic assay, we exemplify how \r\nadhesion
    signaling and cell mechanics function together to modulate the spatial \r\norganization
    of cell-cell contacts."

  text: "The scope of this thesis is to study quantum systems exhibiting a continuous
    symmetry that\r\nis broken on the level of the corresponding effective theory.
    In particular we are going to\r\ninvestigate translation-invariant Bose gases
    in the mean field limit, effectively described by\r\nthe Hartree functional, and
    the Fröhlich Polaron in the regime of strong coupling, effectively\r\ndescribed
    by the Pekar functional. The latter is a model describing the interaction between
    a\r\ncharged particle and the optical modes of a polar crystal. Regarding the
    former, we assume in\r\naddition that the particles in the gas are unconfined,
    and typically we will consider particles\r\nthat are subject to an attractive
    interaction. In both cases the ground state energy of the\r\nHamiltonian is not
    a proper eigenvalue due to the underlying translation-invariance, while on\r\nthe
    contrary there exists a whole invariant orbit of minimizers for the corresponding
    effective\r\nfunctionals. Both, the absence of proper eigenstates and the broken
    symmetry of the effective\r\ntheory, make the study significantly more involved
    and it is the content of this thesis to\r\ndevelop a frameworks which allows for
    a systematic way to circumvent these issues.\r\nIt is a well-established result
    that the ground state energy of Bose gases in the mean field limit,\r\nas well
    as the ground state energy of the Fröhlich Polaron in the regime of strong coupling,
    is\r\nto leading order given by the minimal energy of the corresponding effective
    theory. As part\r\nof this thesis we identify the sub-leading term in the expansion
    of the ground state energy,\r\nwhich can be interpreted as the quantum correction
    to the classical energy, since the effective\r\ntheories under consideration can
    be seen as classical counterparts.\r\nWe are further going to establish an asymptotic
    expression for the energy-momentum relation\r\nof the Fröhlich Polaron in the
    strong coupling limit. In the regime of suitably small momenta,\r\nthis asymptotic
    expression agrees with the energy-momentum relation of a free particle having\r\nan
    effectively increased mass, and we find that this effectively increased mass agrees
    with the\r\nconjectured value in the physics literature.\r\nIn addition we will
    discuss two unrelated papers written by the author during his stay at ISTA\r\nin
    the appendix. The first one concerns the realization of anyons, which are quasi-particles\r\nacquiring
    a non-trivial phase under the exchange of two particles, as molecular impurities.\r\nThe
    second one provides a classification of those vector fields defined on a given
    manifold\r\nthat can be written as the gradient of a given functional with respect
    to a suitable metric,\r\nprovided that some mild smoothness assumptions hold.
    This classification is subsequently\r\nused to identify those quantum Markov semigroups
    that can be written as a gradient flow of\r\nthe relative entropy.\r\n"

  text: This paper presents a new representation of curve dynamics, with applications
    to vortex filaments in fluid dynamics. Instead of representing these filaments
    with explicit curve geometry and Lagrangian equations of motion, we represent
    curves implicitly with a new co-dimensional 2 level set description. Our implicit
    representation admits several redundant mathematical degrees of freedom in both
    the configuration and the dynamics of the curves, which can be tailored specifically
    to improve numerical robustness, in contrast to naive approaches for implicit
    curve dynamics that suffer from overwhelming numerical stability problems. Furthermore,
    we note how these hidden degrees of freedom perfectly map to a Clebsch representation
    in fluid dynamics. Motivated by these observations, we introduce untwisted level
    set functions and non-swirling dynamics which successfully regularize sources
    of numerical instability, particularly in the twisting modes around curve filaments.
    A consequence is a novel simulation method which produces stable dynamics for
    large numbers of interacting vortex filaments and effortlessly handles topological
    changes and re-connection events.

  text: Portrait viewpoint and illumination editing is an important problem with several
    applications in VR/AR, movies, and photography. Comprehensive knowledge of geometry
    and illumination is critical for obtaining photorealistic results. Current methods
    are unable to explicitly model in 3D while handing both viewpoint and illumination
    editing from a single image. In this paper, we propose VoRF, a novel approach
    that can take even a single portrait image as input and relight human heads under
    novel illuminations that can be viewed from arbitrary viewpoints. VoRF represents
    a human head as a continuous volumetric field and learns a prior model of human
    heads using a coordinate-based MLP with separate latent spaces for identity and
    illumination. The prior model is learnt in an auto-decoder manner over a diverse
    class of head shapes and appearances, allowing VoRF to generalize to novel test
    identities from a single input image. Additionally, VoRF has a reflectance MLP
    that uses the intermediate features of the prior model for rendering One-Light-at-A-Time
    (OLAT) images under novel views. We synthesize novel illuminations by combining
    these OLAT images with target environment maps. Qualitative and quantitative evaluations
    demonstrate the effectiveness of VoRF for relighting and novel view synthesis
    even when applied to unseen subjects under uncontrolled illuminations.

  text: 'We consider the problem of estimating a signal from measurements obtained
    via a generalized linear model. We focus on estimators based on approximate message
    passing (AMP), a family of iterative algorithms with many appealing features:
    the performance of AMP in the high-dimensional limit can be succinctly characterized
    under suitable model assumptions; AMP can also be tailored to the empirical distribution
    of the signal entries, and for a wide class of estimation problems, AMP is conjectured
    to be optimal among all polynomial-time algorithms. However, a major issue of
    AMP is that in many models (such as phase retrieval), it requires an initialization
    correlated with the ground-truth signal and independent from the measurement matrix.
    Assuming that such an initialization is available is typically not realistic.
    In this paper, we solve this problem by proposing an AMP algorithm initialized
    with a spectral estimator. With such an initialization, the standard AMP analysis
    fails since the spectral estimator depends in a complicated way on the design
    matrix. Our main contribution is a rigorous characterization of the performance
    of AMP with spectral initialization in the high-dimensional limit. The key technical
    idea is to define and analyze a two-phase artificial AMP algorithm that first
    produces the spectral estimator, and then closely approximates the iterates of
    the true AMP. We also provide numerical results that demonstrate the validity
    of the proposed approach.'

  text: "Fairness-aware learning aims at constructing classifiers that not only make
    accurate predictions, but also do not discriminate against specific groups. It
    is a fast-growing area of\r\nmachine learning with far-reaching societal impact.
    However, existing fair learning methods\r\nare vulnerable to accidental or malicious
    artifacts in the training data, which can cause\r\nthem to unknowingly produce
    unfair classifiers. In this work we address the problem of\r\nfair learning from
    unreliable training data in the robust multisource setting, where the\r\navailable
    training data comes from multiple sources, a fraction of which might not be representative
    of the true data distribution. We introduce FLEA, a filtering-based algorithm\r\nthat
    identifies and suppresses those data sources that would have a negative impact
    on\r\nfairness or accuracy if they were used for training. As such, FLEA is not
    a replacement of\r\nprior fairness-aware learning methods but rather an augmentation
    that makes any of them\r\nrobust against unreliable training data. We show the
    effectiveness of our approach by a\r\ndiverse range of experiments on multiple
    datasets. Additionally, we prove formally that\r\n–given enough data– FLEA protects
    the learner against corruptions as long as the fraction of\r\naffected data sources
    is less than half. Our source code and documentation are available at\r\nhttps://github.com/ISTAustria-CVML/FLEA."

  text: A graph game is a two-player zero-sum game in which the players move a token
    throughout a graph to produce an infinite path, which determines the winner or
    payoff of the game. In bidding games, both players have budgets, and in each turn,
    we hold an "auction" (bidding) to determine which player moves the token. In this
    survey, we consider several bidding mechanisms and their effect on the properties
    of the game. Specifically, bidding games, and in particular bidding games of infinite
    duration, have an intriguing equivalence with random-turn games in which in each
    turn, the player who moves is chosen randomly. We summarize how minor changes
    in the bidding mechanism lead to unexpected differences in the equivalence with
    random-turn games.

abstract:
- lang: eng
  text: "We introduce a new statistical verification algorithm that formally quantifies
    the behavioral robustness of any time-continuous process formulated as a continuous-depth
    model. Our algorithm solves a set of global optimization (Go) problems over a
    given time horizon to construct a tight enclosure (Tube) of the set of all process
    executions starting from a ball of initial states. We call our algorithm GoTube.
    Through its construction, GoTube ensures that the bounding tube is conservative
    up to a desired probability and up to a desired tightness.\r\n GoTube is implemented
    in JAX and optimized to scale to complex continuous-depth neural network models.
    Compared to advanced reachability analysis tools for time-continuous neural networks,
    GoTube does not accumulate overapproximation errors between time steps and avoids
    the infamous wrapping effect inherent in symbolic techniques. We show that GoTube
    substantially outperforms state-of-the-art verification tools in terms of the
    size of the initial ball, speed, time-horizon, task completion, and scalability
    on a large set of experiments.\r\n GoTube is stable and sets the state-of-the-art
    in terms of its ability to scale to time horizons well beyond what has been previously
    possible."

  text: "We consider the problem of formally verifying almost-sure (a.s.) asymptotic
    stability in discrete-time nonlinear stochastic control systems. While verifying
    stability in deterministic control systems is extensively studied in the literature,
    verifying stability in stochastic control systems is an open problem. The few
    existing works on this topic either consider only specialized forms of stochasticity
    or make restrictive assumptions on the system, rendering them inapplicable to
    learning algorithms with neural network policies. \r\n In this work, we present
    an approach for general nonlinear stochastic control problems with two novel aspects:
    (a) instead of classical stochastic extensions of Lyapunov functions, we use ranking
    supermartingales (RSMs) to certify a.s. asymptotic stability, and (b) we present
    a method for learning neural network RSMs. \r\n We prove that our approach guarantees
    a.s. asymptotic stability of the system and\r\n provides the first method to obtain
    bounds on the stabilization time, which stochastic Lyapunov functions do not.\r\n
    Finally, we validate our approach experimentally on a set of nonlinear stochastic
    reinforcement learning environments with neural network policies."

  text: "The homogeneous continuous LWE (hCLWE) problem is to distinguish samples
    of a specific high-dimensional Gaussian mixture from standard normal samples.
    It was shown to be at least as hard as Learning with Errors, but no reduction
    in the other direction is currently known.\r\nWe present four new public-key encryption
    schemes based on the hardness of hCLWE, with varying tradeoffs between decryption
    and security errors, and different discretization techniques. Our schemes yield
    a polynomial-time algorithm for solving hCLWE using a Statistical Zero-Knowledge
    oracle."

  text: "We consider turn-based stochastic 2-player games on graphs with ω-regular
    winning conditions. We provide a direct symbolic algorithm for solving such games
    when the winning condition is formulated as a Rabin condition. For a stochastic
    Rabin game with k pairs over a game graph with n vertices, our algorithm runs
    in O(nk+2k!) symbolic steps, which improves the state of the art.\r\nWe have implemented
    our symbolic algorithm, along with performance optimizations including parallellization
    and acceleration, in a BDD-based synthesis tool called Fairsyn. We demonstrate
    the superiority of Fairsyn compared to the state of the art on a set of synthetic
    benchmarks derived from the VLTS benchmark suite and on a control system benchmark
    from the literature. In our experiments, Fairsyn performed significantly faster
    with up to two orders of magnitude improvement in computation time."

  text: We present BOCoSy, a tool for Bounded symbolic Output-feedback Controller
    Synthesis. Given a specification, BOCoSy synthesizes symbolic output-feedback
    controllers which interact with a given plant via a pre-defined finite symbolic
    interface. BOCoSy solves this problem by a new lazy abstraction-refinement technique
    which starts with a very coarse abstraction of the external trace semantics of
    the given plant and iteratively removes non-admissible behavior from this abstract
    model until a controller is found. BOCoSy steers the search for controllers towards
    small and concise state space representations by utilizing ideas from bounded
    synthesis. As a result, BOCoSy returns small and explainable controllers that
    are still powerful enough to solve the given synthesis problem. We show that BOCoSy
    is able to synthesize small, human readable symbolic controllers quickly on a
    set of benchmarks.

  text: In this paper, we study the compression of a target two-layer neural network
    with N nodes into a compressed network with M<N nodes. More precisely, we consider
    the setting in which the weights of the target network are i.i.d. sub-Gaussian,
    and we minimize the population L_2 loss between the outputs of the target and
    of the compressed network, under the assumption of Gaussian inputs. By using tools
    from high-dimensional probability, we show that this non-convex problem can be
    simplified when the target network is sufficiently over-parameterized, and provide
    the error rate of this approximation as a function of the input dimension and
    N. In this mean-field limit, the simplified objective, as well as the optimal
    weights of the compressed network, does not depend on the realization of the target
    network, but only on expected scaling factors. Furthermore, for networks with
    ReLU activation, we conjecture that the optimum of the simplified optimization
    problem is achieved by taking weights on the Equiangular Tight Frame (ETF), while
    the scaling of the weights and the orientation of the ETF depend on the parameters
    of the target network. Numerical evidence is provided to support this conjecture.

  text: We consider the problem of signal estimation in generalized linear models
    defined via rotationally invariant design matrices. Since these matrices can have
    an arbitrary spectral distribution, this model is well suited for capturing complex
    correlation structures which often arise in applications. We propose a novel family
    of approximate message passing (AMP) algorithms for signal estimation, and rigorously
    characterize their performance in the high-dimensional limit via a state evolution
    recursion. Our rotationally invariant AMP has complexity of the same order as
    the existing AMP derived under the restrictive assumption of a Gaussian design;
    our algorithm also recovers this existing AMP as a special case. Numerical results
    showcase a performance close to Vector AMP (which is conjectured to be Bayes-optimal
    in some settings), but obtained with a much lower complexity, as the proposed
    algorithm does not require a computationally expensive singular value decomposition.

  text: We treat the problem of risk-aware control for stochastic shortest path (SSP)
    on Markov decision processes (MDP). Typically, expectation is considered for SSP,
    which however is oblivious to the incurred risk. We present an alternative view,
    instead optimizing conditional value-at-risk (CVaR), an established risk measure.
    We treat both Markov chains as well as MDP and introduce, through novel insights,
    two algorithms, based on linear programming and value iteration, respectively.
    Both algorithms offer precise and provably correct solutions. Evaluation of our
    prototype implementation shows that risk-aware control is feasible on several
    moderately sized models.

  text: Melt from supraglacial ice cliffs is an important contributor to the mass
    loss of debris-covered glaciers. However, ice cliff contribution is difficult
    to quantify as they are highly dynamic features, and the paucity of observations
    of melt rates and their variability leads to large modelling uncertainties. We
    quantify monsoon season melt and 3D evolution of four ice cliffs over two debris-covered
    glaciers in High Mountain Asia (Langtang Glacier, Nepal, and 24K Glacier, China)
    at very high resolution using terrestrial photogrammetry applied to imagery captured
    from time-lapse cameras installed on lateral moraines. We derive weekly flow-corrected
    digital elevation models (DEMs) of the glacier surface with a maximum vertical
    bias of ±0.2 m for Langtang Glacier and ±0.05 m for 24K Glacier and use change
    detection to determine distributed melt rates at the surfaces of the ice cliffs
    throughout the study period. We compare the measured melt patterns with those
    derived from a 3D energy balance model to derive the contribution of the main
    energy fluxes. We find that ice cliff melt varies considerably throughout the
    melt season, with maximum melt rates of 5 to 8 cm d−1, and their average melt
    rates are 11–14 (Langtang) and 4.5 (24K) times higher than the surrounding debris-covered
    ice. Our results highlight the influence of redistributed supraglacial debris
    on cliff melt. At both sites, ice cliff albedo is influenced by the presence of
    thin debris at the ice cliff surface, which is largely controlled on 24K Glacier
    by liquid precipitation events that wash away this debris. Slightly thicker or
    patchy debris reduces melt by 1–3 cm d−1 at all sites. Ultimately, our observations
    show a strong spatio-temporal variability in cliff area at each site, which is
    controlled by supraglacial streams and ponds and englacial cavities that promote
    debris slope destabilisation and the lateral expansion of the cliffs. These findings
    highlight the need to better represent processes of debris redistribution in ice
    cliff models, to in turn improve estimates of ice cliff contribution to glacier
    melt and the long-term geomorphological evolution of debris-covered glacier surfaces.

  text: The current Chilean megadrought has led to acute water shortages in central
    Chile since 2010. Glaciers have provided vital fresh water to the region's rivers,
    but the quantity, timing and sustainability of that provision remain unclear.
    Here we combine in-situ, remote sensing and climate reanalysis data to show that
    from 2010 to 2018 during the megadrought, unsustainable imbalance ablation of
    glaciers (ablation not balanced by new snowfall) strongly buffered the late-summer
    discharge of the Maipo River, a primary source of water to Santiago. If there
    had been no glaciers, water availability would have been reduced from December
    through May, with a 31 ± 19% decrease during March. Our results indicate that
    while the annual contributions of imbalance ablation to river discharge during
    the megadrought have been small compared to those from precipitation and sustainable
    balance ablation, they have nevertheless been a substantial input to a hydrological
    system that was already experiencing high water stress. The water-equivalent volume
    of imbalance ablation generated in the Maipo Basin between 2010 and 2018 was 740
    × 106 m3 (19 ± 12 mm yr−1), approximately 3.4 times the capacity of the basin's
    El Yeso Reservoir. This is equivalent to 14% of Santiago's potable water use in
    that time, while total glacier ablation was equivalent to 59%. We show that glacier
    retreat will exacerbate river discharge deficits and further jeopardize water
    availability in central Chile if precipitation deficits endure, and conjecture
    that these effects will be amplified by climatic warming.

  text: Glacier health across High Mountain Asia (HMA) is highly heterogeneous and
    strongly governed by regional climate, which is variably influenced by monsoon
    dynamics and the westerlies. We explore four decades of glacier energy and mass
    balance at three climatically distinct sites across HMA by utilising a detailed
    land surface model driven by bias-corrected Weather Research and Forecasting meteorological
    forcing. All three glaciers have experienced long-term mass losses (ranging from
    −0.04 ± 0.09 to −0.59 ± 0.20 m w.e. a<jats:sup>−1</jats:sup>) consistent with
    widespread warming across the region. However, complex and contrasting responses
    of glacier energy and mass balance to the patterns of the Indian Summer Monsoon
    were evident, largely driven by the role snowfall timing, amount and phase. A
    later monsoon onset generates less total snowfall to the glacier in the southeastern
    Tibetan Plateau during May–June, augmenting net shortwave radiation and affecting
    annual mass balance (−0.5 m w.e. on average compared to early onset years). Conversely,
    timing of the monsoon’s arrival has limited impact for the Nepalese Himalaya which
    is more strongly governed by the temperature and snowfall amount during the core
    monsoon season. In the arid central Tibetan Plateau, a later monsoon arrival results
    in a 40 mm (58%) increase of May–June snowfall on average compared to early onset
    years, likely driven by the greater interaction of westerly storm events. Meanwhile,
    a late monsoon cessation at this site sees an average 200 mm (192%) increase in
    late summer precipitation due to monsoonal storms. A trend towards weaker intensity
    monsoon conditions in recent decades, combined with long-term warming patterns,
    has produced predominantly negative glacier mass balances for all sites (up to
    1 m w.e. more mass loss in the Nepalese Himalaya compared to strong monsoon intensity
    years) but sub-regional variability in monsoon timing can additionally complicate
    this response.
