  text: We prove a central limit theorem for the difference of linear eigenvalue statistics
    of a sample covariance matrix W˜ and its minor W. We find that the fluctuation
    of this difference is much smaller than those of the individual linear statistics,
    as a consequence of the strong correlation between the eigenvalues of W˜ and W.
    Our result identifies the fluctuation of the spatial derivative of the approximate
    Gaussian field in the recent paper by Dumitru and Paquette. Unlike in a similar
    result for Wigner matrices, for sample covariance matrices, the fluctuation may
    entirely vanish.

  text: "This paper presents two algorithms. The first decides the existence of a
    pointed homotopy between given simplicial maps \U0001D453,\U0001D454:\U0001D44B→\U0001D44C,
    and the second computes the group [\U0001D6F4\U0001D44B,\U0001D44C]∗ of pointed
    homotopy classes of maps from a suspension; in both cases, the target Y is assumed
    simply connected. More generally, these algorithms work relative to \U0001D434⊆\U0001D44B."

  text: 'We consider the monotone variational inequality problem in a Hilbert space
    and describe a projection-type method with inertial terms under the following
    properties: (a) The method generates a strongly convergent iteration sequence;
    (b) The method requires, at each iteration, only one projection onto the feasible
    set and two evaluations of the operator; (c) The method is designed for variational
    inequality for which the underline operator is monotone and uniformly continuous;
    (d) The method includes an inertial term. The latter is also shown to speed up
    the convergence in our numerical results. A comparison with some related methods
    is given and indicates that the new method is promising.'

  text: "While Hartree–Fock theory is well established as a fundamental approximation
    for interacting fermions, it has been unclear how to describe corrections to it
    due to many-body correlations. In this paper we start from the Hartree–Fock state
    given by plane waves and introduce collective particle–hole pair excitations.
    These pairs can be approximately described by a bosonic quadratic Hamiltonian.
    We use Bogoliubov theory to construct a trial state yielding a rigorous Gell-Mann–Brueckner–type
    upper bound to the ground state energy. Our result justifies the random-phase
    approximation in the mean-field scaling regime, for repulsive, regular interaction
    potentials.\r\n"

  text: "Fitting a function by using linear combinations of a large number N of `simple'
    components is one of the most fruitful ideas in statistical learning. This idea
    lies at the core of a variety of methods, from two-layer neural networks to kernel
    regression, to boosting. In general, the resulting risk minimization problem is
    non-convex and is solved by gradient descent or its variants. Unfortunately, little
    is known about global convergence properties of these approaches.\r\nHere we consider
    the problem of learning a concave function f on a compact convex domain Ω⊆ℝd,
    using linear combinations of `bump-like' components (neurons). The parameters
    to be fitted are the centers of N bumps, and the resulting empirical risk minimization
    problem is highly non-convex. We prove that, in the limit in which the number
    of neurons diverges, the evolution of gradient descent converges to a Wasserstein
    gradient flow in the space of probability distributions over Ω. Further, when
    the bump width δ tends to 0, this gradient flow has a limit which is a viscous
    porous medium equation. Remarkably, the cost function optimized by this gradient
    flow exhibits a special property known as displacement convexity, which implies
    exponential convergence rates for N→∞, δ→0. Surprisingly, this asymptotic theory
    appears to capture well the behavior for moderate values of δ,N. Explaining this
    phenomenon, and understanding the dependence on δ,N in a quantitative manner remains
    an outstanding challenge."

  text: In resource allocation games, selfish players share resources that are needed
    in order to fulfill their objectives. The cost of using a resource depends on
    the load on it. In the traditional setting, the players make their choices concurrently
    and in one-shot. That is, a strategy for a player is a subset of the resources.
    We introduce and study dynamic resource allocation games. In this setting, the
    game proceeds in phases. In each phase each player chooses one resource. A scheduler
    dictates the order in which the players proceed in a phase, possibly scheduling
    several players to proceed concurrently. The game ends when each player has collected
    a set of resources that fulfills his objective. The cost for each player then
    depends on this set as well as on the load on the resources in it – we consider
    both congestion and cost-sharing games. We argue that the dynamic setting is the
    suitable setting for many applications in practice. We study the stability of
    dynamic resource allocation games, where the appropriate notion of stability is
    that of subgame perfect equilibrium, study the inefficiency incurred due to selfish
    behavior, and also study problems that are particular to the dynamic setting,
    like constraints on the order in which resources can be chosen or the problem
    of finding a scheduler that achieves stability.

  text: Nearby grid cells have been observed to express a remarkable degree of long-rangeorder,
    which is often idealized as extending potentially to infinity. Yet their strict
    peri-odic firing and ensemble coherence are theoretically possible only in flat
    environments, much unlike the burrows which rodents usually live in. Are the symmetrical,
    coherent grid maps inferred in the lab relevant to chart their way in their natural
    habitat? We consider spheres as simple models of curved environments and waiting
    for the appropriate experiments to be performed, we use our adaptation model to
    predict what grid maps would emerge in a network with the same type of recurrent
    connections, which on the plane produce coherence among the units. We find that
    on the sphere such connections distort the maps that single grid units would express
    on their own, and aggregate them into clusters. When remapping to a different
    spherical environment, units in each cluster maintain only partial coherence,
    similar to what is observed in disordered materials, such as spin glasses.

  text: Super-resolution fluorescence microscopy has become an important catalyst
    for discovery in the life sciences. In STimulated Emission Depletion (STED) microscopy,
    a pattern of light drives fluorophores from a signal-emitting on-state to a non-signalling
    off-state. Only emitters residing in a sub-diffraction volume around an intensity
    minimum are allowed to fluoresce, rendering them distinguishable from the nearby,
    but dark fluorophores. STED routinely achieves resolution in the few tens of nanometers
    range in biological samples and is suitable for live imaging. Here, we review
    the working principle of STED and provide general guidelines for successful STED
    imaging. The strive for ever higher resolution comes at the cost of increased
    light burden. We discuss techniques to reduce light exposure and mitigate its
    detrimental effects on the specimen. These include specialized illumination strategies
    as well as protecting fluorophores from photobleaching mediated by high-intensity
    STED light. This opens up the prospect of volumetric imaging in living cells and
    tissues with diffraction-unlimited resolution in all three spatial dimensions.

  text: We consider systems of bosons trapped in a box, in the Gross–Pitaevskii regime.
    We show that low-energy states exhibit complete Bose–Einstein condensation with
    an optimal bound on the number of orthogonal excitations. This extends recent
    results obtained in Boccato et al. (Commun Math Phys 359(3):975–1026, 2018), removing
    the assumption of small interaction potential.

  text: We prove that in the absence of topological changes, the notion of BV solutions
    to planar multiphase mean curvature flow does not allow for a mechanism for (unphysical)
    non-uniqueness. Our approach is based on the local structure of the energy landscape
    near a classical evolution by mean curvature. Mean curvature flow being the gradient
    flow of the surface energy functional, we develop a gradient-flow analogue of
    the notion of calibrations. Just like the existence of a calibration guarantees
    that one has reached a global minimum in the energy landscape, the existence of
    a "gradient flow calibration" ensures that the route of steepest descent in the
    energy landscape is unique and stable.

  text: We consider finite-volume approximations of Fokker-Planck equations on bounded
    convex domains in R^d and study the corresponding gradient flow structures. We
    reprove the convergence of the discrete to continuous Fokker-Planck equation via
    the method of Evolutionary Γ-convergence, i.e., we pass to the limit at the level
    of the gradient flow structures, generalising the one-dimensional result obtained
    by Disser and Liero. The proof is of variational nature and relies on a Mosco
    convergence result for functionals in the discrete-to-continuum limit that is
    of independent interest. Our results apply to arbitrary regular meshes, even though
    the associated discrete transport distances may fail to converge to the Wasserstein
    distance in this generality.

  text: In this paper, we present the first Asynchronous Distributed Key Generation
    (ADKG) algorithm which is also the first distributed key generation algorithm
    that can generate cryptographic keys with a dual (f,2f+1)-threshold (where f is
    the number of faulty parties). As a result, using our ADKG we remove the trusted
    setup assumption that the most scalable consensus algorithms make. In order to
    create a DKG with a dual (f,2f+1)- threshold we first answer in the affirmative
    the open question posed by Cachin et al. [7] on how to create an Asynchronous
    Verifiable Secret Sharing (AVSS) protocol with a reconstruction threshold of f+1<k
    łe 2f+1, which is of independent interest. Our High-threshold-AVSS (HAVSS) uses
    an asymmetric bivariate polynomial to encode the secret. This enables the reconstruction
    of the secret only if a set of k nodes contribute while allowing an honest node
    that did not participate in the sharing phase to recover his share with the help
    of f+1 honest parties. Once we have HAVSS we can use it to bootstrap scalable
    partially synchronous consensus protocols, but the question on how to get a DKG
    in asynchrony remains as we need a way to produce common randomness. The solution
    comes from a novel Eventually Perfect Common Coin (EPCC) abstraction that enables
    the generation of a common coin from n concurrent HAVSS invocations. EPCC's key
    property is that it is eventually reliable, as it might fail to agree at most
    f times (even if invoked a polynomial number of times). Using EPCC we implement
    an Eventually Efficient Asynchronous Binary Agreement (EEABA) which is optimal
    when the EPCC agrees and protects safety when EPCC fails. Finally, using EEABA
    we construct the first ADKG which has the same overhead and expected runtime as
    the best partially-synchronous DKG (O(n4) words, O(f) rounds). As a corollary
    of our ADKG, we can also create the first Validated Asynchronous Byzantine Agreement
    (VABA) that does not need a trusted dealer to setup threshold signatures of degree
    n-f. Our VABA has an overhead of expected O(n2) words and O(1) time per instance,
    after an initial O(n4) words and O(f) time bootstrap via ADKG.
acknowledgement: We would like to thank Ittai Abraham for the discussions and guidance
  during the initial conception of the project, especially for HAVSS. Furthermore,
  we would like to thank the anonymous reviewers for pointing out the relevance of
  this work to MPC protocols.

  text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
    motivated alternative to backpropagation (BP), by substituting the computations
    that are unrealistic to be implemented in physical brains. While FA algorithms
    have been shown to work well in practice, there is a lack of rigorous theory proofing
    their learning capabilities. Here we introduce the first feedback alignment algorithm
    with provable learning guarantees. In contrast to existing work, we do not require
    any assumption about the size or depth of the network except that it has a single
    output neuron, i.e., such as for binary classification tasks. We show that our
    FA algorithm can deliver its theoretical promises in practice, surpassing the
    learning performance of existing FA methods and matching backpropagation in binary
    classification tasks. Finally, we demonstrate the limits of our FA variant when
    the number of output neurons grows beyond a certain quantity.

  text: We propose a neural information processing system obtained by re-purposing
    the function of a biological neural circuit model to govern simulated and real-world
    control tasks. Inspired by the structure of the nervous system of the soil-worm,
    C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model
    of biological neural circuits reparameterized for the control of alternative tasks.
    We first demonstrate that ONCs realize networks with higher maximum flow compared
    to arbitrary wired networks. We then learn instances of ONCs to control a series
    of robotic tasks, including the autonomous parking of a real-world rover robot.
    For reconfiguration of the purpose of the neural circuit, we adopt a search-based
    optimization algorithm. Ordinary neural circuits perform on par and, in some cases,
    significantly surpass the performance of contemporary deep learning models. ONC
    networks are compact, 77% sparser than their counterpart neural controllers, and
    their neural dynamics are fully interpretable at the cell-level.

  text: 'Optimizing convolutional neural networks for fast inference has recently
    become an extremely active area of research. One of the go-to solutions in this
    context is weight pruning, which aims to reduce computational and memory footprint
    by removing large subsets of the connections in a neural network. Surprisingly,
    much less attention has been given to exploiting sparsity in the activation maps,
    which tend to be naturally sparse in many settings thanks to the structure of
    rectified linear (ReLU) activation functions. In this paper, we present an in-depth
    analysis of methods for maximizing the sparsity of the activations in a trained
    neural network, and show that, when coupled with an efficient sparse-input convolution
    algorithm, we can leverage this sparsity for significant performance gains. To
    induce highly sparse activation maps without accuracy loss, we introduce a new
    regularization technique, coupled with a new threshold-based sparsification method
    based on a parameterized activation function called Forced-Activation-Threshold
    Rectified Linear Unit (FATReLU). We examine the impact of our methods on popular
    image classification models, showing that most architectures can adapt to significantly
    sparser activation maps without any accuracy loss. Our second contribution is
    showing that these these compression gains can be translated into inference speedups:
    we provide a new algorithm to enable fast convolution operations over networks
    with sparse activations, and show that it can enable significant speedups for
    end-to-end inference on a range of popular models on the large-scale ImageNet
    image classification task on modern Intel CPUs, with little or no retraining cost. '

  text: DNA methylation and histone H1 mediate transcriptional silencing of genes
    and transposable elements, but how they interact is unclear. In plants and animals
    with mosaic genomic methylation, functionally mysterious methylation is also common
    within constitutively active housekeeping genes. Here, we show that H1 is enriched
    in methylated sequences, including genes, of Arabidopsis thaliana, yet this enrichment
    is independent of DNA methylation. Loss of H1 disperses heterochromatin, globally
    alters nucleosome organization, and activates H1-bound genes, but only weakly
    de-represses transposable elements. However, H1 loss strongly activates transposable
    elements hypomethylated through mutation of DNA methyltransferase MET1. Hypomethylation
    of genes also activates antisense transcription, which is modestly enhanced by
    H1 loss. Our results demonstrate that H1 and DNA methylation jointly maintain
    transcriptional homeostasis by silencing transposable elements and aberrant intragenic
    transcripts. Such functionality plausibly explains why DNA methylation, a well-known
    mutagen, has been maintained within coding sequences of crucial plant and animal
    genes.

  text: Various kinds of data are routinely represented as discrete probability distributions.
    Examples include text documents summarized by histograms of word occurrences and
    images represented as histograms of oriented gradients. Viewing a discrete probability
    distribution as a point in the standard simplex of the appropriate dimension,
    we can understand collections of such objects in geometric and topological terms.  Importantly,
    instead of using the standard Euclidean distance, we look into dissimilarity measures
    with information-theoretic justification, and we develop the theory needed for
    applying topological data analysis in this setting. In doing so, we emphasize
    constructions that enable the usage of existing computational topology software
    in this context.

  text: The ability to leverage large-scale hardware parallelism has been one of the
    key enablers of the accelerated recent progress in machine learning. Consequently,
    there has been considerable effort invested into developing efficient parallel
    variants of classic machine learning algorithms. However, despite the wealth of
    knowledge on parallelization, some classic machine learning algorithms often prove
    hard to parallelize efficiently while maintaining convergence. In this paper,
    we focus on efficient parallel algorithms for the key machine learning task of
    inference on graphical models, in particular on the fundamental belief propagation
    algorithm. We address the challenge of efficiently parallelizing this classic
    paradigm by showing how to leverage scalable relaxed schedulers in this context.
    We present an extensive empirical study, showing that our approach outperforms
    previous parallel belief propagation implementations both in terms of scalability
    and in terms of wall-clock convergence time, on a range of practical applications.
