  text: Attempts to incorporate topological information in supervised learning tasks
    have resulted in the creation of several techniques for vectorizing persistent
    homology barcodes. In this paper, we study thirteen such methods. Besides describing
    an organizational framework for these methods, we comprehensively benchmark them
    against three well-known classification tasks. Surprisingly, we discover that
    the best-performing method is a simple vectorization, which consists only of a
    few elementary summary statistics. Finally, we provide a convenient web application
    which has been designed to facilitate exploration and experimentation with various
    vectorization methods.

  text: We introduce a machine-learning (ML) framework for high-throughput benchmarking
    of diverse representations of chemical systems against datasets of materials and
    molecules. The guiding principle underlying the benchmarking approach is to evaluate
    raw descriptor performance by limiting model complexity to simple regression schemes
    while enforcing best ML practices, allowing for unbiased hyperparameter optimization,
    and assessing learning progress through learning curves along series of synchronized
    train-test splits. The resulting models are intended as baselines that can inform
    future method development, in addition to indicating how easily a given dataset
    can be learnt. Through a comparative analysis of the training outcome across a
    diverse set of physicochemical, topological and geometric representations, we
    glean insight into the relative merits of these representations as well as their
    interrelatedness.

  text: Standard epidemic models exhibit one continuous, second order phase transition
    to macroscopic outbreaks. However, interventions to control outbreaks may fundamentally
    alter epidemic dynamics. Here we reveal how such interventions modify the type
    of phase transition. In particular, we uncover three distinct types of explosive
    phase transitions for epidemic dynamics with capacity-limited interventions. Depending
    on the capacity limit, interventions may (i) leave the standard second order phase
    transition unchanged but exponentially suppress the probability of large outbreaks,
    (ii) induce a first-order discontinuous transition to macroscopic outbreaks, or
    (iii) cause a secondary explosive yet continuous third-order transition. These
    insights highlight inherent limitations in predicting and containing epidemic
    outbreaks. More generally our study offers a cornerstone example of a third-order
    explosive phase transition in complex systems.

  text: Continuous-time neural networks are a class of machine learning systems that
    can tackle representation learning on spatiotemporal decision-making tasks. These
    models are typically represented by continuous differential equations. However,
    their expressive power when they are deployed on computers is bottlenecked by
    numerical differential equation solvers. This limitation has notably slowed down
    the scaling and understanding of numerous natural physical phenomena such as the
    dynamics of nervous systems. Ideally, we would circumvent this bottleneck by solving
    the given dynamical system in closed form. This is known to be intractable in
    general. Here, we show that it is possible to closely approximate the interaction
    between neurons and synapses—the building blocks of natural and artificial neural
    networks—constructed by liquid time-constant networks efficiently in closed form.
    To this end, we compute a tightly bounded approximation of the solution of an
    integral appearing in liquid time-constant dynamics that has had no known closed-form
    solution so far. This closed-form solution impacts the design of continuous-time
    and continuous-depth neural models. For instance, since time appears explicitly
    in closed form, the formulation relaxes the need for complex numerical solvers.
    Consequently, we obtain models that are between one and five orders of magnitude
    faster in training and inference compared with differential equation-based counterparts.
    More importantly, in contrast to ordinary differential equation-based continuous
    networks, closed-form networks can scale remarkably well compared with other deep
    learning instances. Lastly, as these models are derived from liquid networks,
    they show good performance in time-series modelling compared with advanced recurrent
    neural network models.

  text: In this paper, we present two new inertial projection-type methods for solving
    multivalued variational inequality problems in finite-dimensional spaces. We establish
    the convergence of the sequence generated by these methods when the multivalued
    mapping associated with the problem is only required to be locally bounded without
    any monotonicity assumption. Furthermore, the inertial techniques that we employ
    in this paper are quite different from the ones used in most papers. Moreover,
    based on the weaker assumptions on the inertial factor in our methods, we derive
    several special cases of our methods. Finally, we present some experimental results
    to illustrate the profits that we gain by introducing the inertial extrapolation
    steps.
