  text: In this paper we introduce and study all-pay bidding games, a class of two
    player, zero-sum games on graphs. The game proceeds as follows. We place a token
    on some vertex in the graph and assign budgets to the two players. Each turn,
    each player submits a sealed legal bid (non-negative and below their remaining
    budget), which is deducted from their budget and the highest bidder moves the
    token onto an adjacent vertex. The game ends once a sink is reached, and Player
    1 pays Player 2 the outcome that is associated with the sink. The players attempt
    to maximize their expected outcome. Our games model settings where effort (of
    no inherent value) needs to be invested in an ongoing and stateful manner. On
    the negative side, we show that even in simple games on DAGs, optimal strategies
    may require a distribution over bids with infinite support. A central quantity
    in bidding games is the ratio of the players budgets. On the positive side, we
    show a simple FPTAS for DAGs, that, for each budget ratio, outputs an approximation
    for the optimal strategy for that ratio. We also implement it, show that it performs
    well, and suggests interesting properties of these games. Then, given an outcome
    c, we show an algorithm for finding the necessary and sufficient initial ratio
    for guaranteeing outcome c with probability 1 and a strategy ensuring such. Finally,
    while the general case has not previously been studied, solving the specific game
    in which Player 1 wins iff he wins the first two auctions, has been long stated
    as an open question, which we solve.

  text: We propose a novel hybridization method for stability analysis that over-approximates
    nonlinear dynamical systems by switched systems with linear inclusion dynamics.
    We observe that existing hybridization techniques for safety analysis that over-approximate
    nonlinear dynamical systems by switched affine inclusion dynamics and provide
    fixed approximation error, do not suffice for stability analysis. Hence, we propose
    a hybridization method that provides a state-dependent error which converges to
    zero as the state tends to the equilibrium point. The crux of our hybridization
    computation is an elegant recursive algorithm that uses partial derivatives of
    a given function to obtain upper and lower bound matrices for the over-approximating
    linear inclusion. We illustrate our method on some examples to demonstrate the
    application of the theory for stability analysis. In particular, our method is
    able to establish stability of a nonlinear system which does not admit a polynomial
    Lyapunov function.

  text: 'The monitoring of event frequencies can be used to recognize behavioral anomalies,
    to identify trends, and to deduce or discard hypotheses about the underlying system.
    For example, the performance of a web server may be monitored based on the ratio
    of the total count of requests from the least and most active clients. Exact frequency
    monitoring, however, can be prohibitively expensive; in the above example it would
    require as many counters as there are clients. In this paper, we propose the efficient
    probabilistic monitoring of common frequency properties, including the mode (i.e.,
    the most common event) and the median of an event sequence. We define a logic
    to express composite frequency properties as a combination of atomic frequency
    properties. Our main contribution is an algorithm that, under suitable probabilistic
    assumptions, can be used to monitor these important frequency properties with
    four counters, independent of the number of different events. Our algorithm samples
    longer and longer subwords of an infinite event sequence. We prove the almost-sure
    convergence of our algorithm by generalizing ergodic theory from increasing-length
    prefixes to increasing-length subwords of an infinite sequence. A similar algorithm
    could be used to learn a connected Markov chain of a given structure from observing
    its outputs, to arbitrary precision, for a given confidence. '

  text: This paper presents a novel abstraction technique for analyzing Lyapunov and
    asymptotic stability of polyhedral switched systems. A polyhedral switched system
    is a hybrid system in which the continuous dynamics is specified by polyhedral
    differential inclusions, the invariants and guards are specified by polyhedral
    sets and the switching between the modes do not involve reset of variables. A
    finite state weighted graph abstracting the polyhedral switched system is constructed
    from a finite partition of the state–space, such that the satisfaction of certain
    graph conditions, such as the absence of cycles with product of weights on the
    edges greater than (or equal) to 1, implies the stability of the system. However,
    the graph is in general conservative and hence, the violation of the graph conditions
    does not imply instability. If the analysis fails to establish stability due to
    the conservativeness in the approximation, a counterexample (cycle with product
    of edge weights greater than or equal to 1) indicating a potential reason for
    the failure is returned. Further, a more precise approximation of the switched
    system can be constructed by considering a finer partition of the state–space
    in the construction of the finite weighted graph. We present experimental results
    on analyzing stability of switched systems using the above method.

  text: Neural networks have demonstrated unmatched performance in a range of classification
    tasks. Despite numerous efforts of the research community, novelty detection remains
    one of the significant limitations of neural networks. The ability to identify
    previously unseen inputs as novel is crucial for our understanding of the decisions
    made by neural networks. At runtime, inputs not falling into any of the categories
    learned during training cannot be classified correctly by the neural network.
    Existing approaches treat the neural network as a black box and try to detect
    novel inputs based on the confidence of the output predictions. However, neural
    networks are not trained to reduce their confidence for novel inputs, which limits
    the effectiveness of these approaches. We propose a framework to monitor a neural
    network by observing the hidden layers. We employ a common abstraction from program
    analysis - boxes - to identify novel behaviors in the monitored layers, i.e.,
    inputs that cause behaviors outside the box. For each neuron, the boxes range
    over the values seen in training. The framework is efficient and flexible to achieve
    a desired trade-off between raising false warnings and detecting novel inputs.
    We illustrate the performance and the robustness to variability in the unknown
    classes on popular image-classification benchmarks.

  text: Quantization converts neural networks into low-bit fixed-point computations
    which can be carried out by efficient integer-only hardware, and is standard practice
    for the deployment of neural networks on real-time embedded devices. However,
    like their real-numbered counterpart, quantized networks are not immune to malicious
    misclassification caused by adversarial attacks. We investigate how quantization
    affects a network’s robustness to adversarial attacks, which is a formal verification
    question. We show that neither robustness nor non-robustness are monotonic with
    changing the number of bits for the representation and, also, neither are preserved
    by quantization from a real-numbered network. For this reason, we introduce a
    verification method for quantized neural networks which, using SMT solving over
    bit-vectors, accounts for their exact, bit-precise semantics. We built a tool
    and analyzed the effect of quantization on a classifier for the MNIST dataset.
    We demonstrate that, compared to our method, existing methods for the analysis
    of real-numbered networks often derive false conclusions about their quantizations,
    both when determining robustness and when detecting attacks, and that existing
    methods for quantized networks often miss attacks. Furthermore, we applied our
    method beyond robustness, showing how the number of bits in quantization enlarges
    the gender bias of a predictor for students’ grades.

  text: Asynchronous programs are notoriously difficult to reason about because they
    spawn computation tasks which take effect asynchronously in a nondeterministic
    way. Devising inductive invariants for such programs requires understanding and
    stating complex relationships between an unbounded number of computation tasks
    in arbitrarily long executions. In this paper, we introduce inductive sequentialization,
    a new proof rule that sidesteps this complexity via a sequential reduction, a
    sequential program that captures every behavior of the original program up to
    reordering of coarse-grained commutative actions. A sequential reduction of a
    concurrent program is easy to reason about since it corresponds to a simple execution
    of the program in an idealized synchronous environment, where processes act in
    a fixed order and at the same speed. We have implemented and integrated our proof
    rule in the CIVL verifier, allowing us to provably derive fine-grained implementations
    of asynchronous programs. We have successfully applied our proof rule to a diverse
    set of message-passing protocols, including leader election protocols, two-phase
    commit, and Paxos.

  text: 'Fixed-point arithmetic is a popular alternative to floating-point arithmetic
    on embedded systems. Existing work on the verification of fixed-point programs
    relies on custom formalizations of fixed-point arithmetic, which makes it hard
    to compare the described techniques or reuse the implementations. In this paper,
    we address this issue by proposing and formalizing an SMT theory of fixed-point
    arithmetic. We present an intuitive yet comprehensive syntax of the fixed-point
    theory, and provide formal semantics for it based on rational arithmetic. We also
    describe two decision procedures for this theory: one based on the theory of bit-vectors
    and the other on the theory of reals. We implement the two decision procedures,

  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: 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: "Second-order information, in the form of Hessian- or Inverse-Hessian-vector
    products, is a fundamental tool for solving optimization problems. Recently, there
    has been significant interest in utilizing this information in the context of
    deep\r\nneural networks; however, relatively little is known about the quality
    of existing approximations in this context. Our work examines this question, identifies
    issues with existing approaches, and proposes a method called WoodFisher to compute
    a faithful and efficient estimate of the inverse Hessian. Our main application
    is to neural network compression, where we build on the classic Optimal Brain
    Damage/Surgeon framework. We demonstrate that WoodFisher significantly outperforms
    popular state-of-the-art methods for oneshot pruning. Further, even when iterative,
    gradual pruning is allowed, our method results in a gain in test accuracy over
    the state-of-the-art approaches, for standard image classification datasets such
    as ImageNet ILSVRC. We examine how our method can be extended to take into account
    first-order information, as well as\r\nillustrate its ability to automatically
    set layer-wise pruning thresholds and perform compression in the limited-data
    regime. The code is available at the following link, https://github.com/IST-DASLab/WoodFisher."

  text: We introduce in this paper AMT2.0, a tool for qualitative and quantitative
    analysis of hybrid continuous and Boolean signals that combine numerical values
    and discrete events. The evaluation of the signals is based on rich temporal specifications
    expressed in extended signal temporal logic, which integrates timed regular expressions
    within signal temporal logic. The tool features qualitative monitoring (property
    satisfaction checking), trace diagnostics for explaining and justifying property
    violations and specification-driven measurement of quantitative features of the
    signal. We demonstrate the tool functionality on several running examples and
    case studies, and evaluate its performance.

  text: 'This report presents the results of a friendly competition for formal verification
    of continuous and hybrid systems with linear continuous dynamics. The friendly
    competition took place as part of the workshop Applied Verification for Continuous
    and Hybrid Systems (ARCH) in 2019. In its third edition, seven tools have been
    applied to solve six different benchmark problems in the category for linear continuous
    dynamics (in alphabetical order): CORA, CORA/SX, HyDRA, Hylaa, JuliaReach, SpaceEx,
    and XSpeed. This report is a snapshot of the current landscape of tools and the
    types of benchmarks they are particularly suited for. Due to the diversity of
    problems, we are not ranking tools, yet the presented results provide one of the
    most complete assessments of tools for the safety verification of continuous and
    hybrid systems with linear continuous dynamics up to this date.</jats:p>'

  text: In this paper, we introduce a novel method to interpret recurrent neural networks
    (RNNs), particularly long short-term memory networks (LSTMs) at the cellular level.
    We propose a systematic pipeline for interpreting individual hidden state dynamics
    within the network using response characterization methods. The ranked contribution
    of individual cells to the network's output is computed by analyzing a set of
    interpretable metrics of their decoupled step and sinusoidal responses. As a result,
    our method is able to uniquely identify neurons with insightful dynamics, quantify
    relationships between dynamical properties and test accuracy through ablation
    analysis, and interpret the impact of network capacity on a network's dynamical
    distribution. Finally, we demonstrate the generalizability and scalability of
    our method by evaluating a series of different benchmark sequential datasets.

  text: We show how to construct temporal testers for the logic MITL, a prominent
    linear-time logic for real-time systems. A temporal tester is a transducer that
    inputs a signal holding the Boolean value of atomic propositions and outputs the
    truth value of a formula along time. Here we consider testers over continuous-time
    Boolean signals that use clock variables to enforce duration constraints, as in
    timed automata. We first rewrite the MITL formula into a “simple” formula using
    a limited set of temporal modalities. We then build testers for these specific
    modalities and show how to compose testers for simple formulae into complex ones.
    Temporal testers can be turned into acceptors, yielding a compositional translation
    from MITL to timed automata. This construction is much simpler than previously
    known and remains asymptotically optimal. It supports both past and future operators
    and can easily be extended.

  text: "The expression of a gene is characterised by its transcription factors and
    the function processing them. If the transcription factors are not affected by
    gene products, the regulating function is often represented as a combinational
    logic circuit, where the outputs (product) are determined by current input values
    (transcription factors) only, and are hence independent on their relative arrival
    times. However, the simultaneous arrival of transcription factors (TFs) in genetic
    circuits is a strong assumption, given that the processes of transcription and
    translation of a gene into a protein introduce intrinsic time delays and that
    there is no global synchronisation among the arrival times of different molecular
    species at molecular targets.\r\n\r\nIn this paper, we construct an experimentally
    implementable genetic circuit with two inputs and a single output, such that,
    in presence of small delays in input arrival, the circuit exhibits qualitatively
    distinct observable phenotypes. In particular, these phenotypes are long lived
    transients: they all converge to a single value, but so slowly, that they seem
    stable for an extended time period, longer than typical experiment duration. We
    used rule-based language to prototype our circuit, and we implemented a search
    for finding the parameter combinations raising the phenotypes of interest.\r\n\r\nThe
    behaviour of our prototype circuit has wide implications. First, it suggests that
    GRNs can exploit event timing to create phenotypes. Second, it opens the possibility
    that GRNs are using event timing to react to stimuli and memorise events, without
    explicit feedback in regulation. From the modelling perspective, our prototype
    circuit demonstrates the critical importance of analysing the transient dynamics
    at the promoter binding sites of the DNA, before applying rapid equilibrium assumptions."

  text: 'Cyber-physical systems (CPS) and the Internet-of-Things (IoT) result in a
    tremendous amount of generated, measured and recorded time-series data. Extracting
    temporal segments that encode patterns with useful information out of these huge
    amounts of data is an extremely difficult problem. We propose shape expressions
    as a declarative formalism for specifying, querying and extracting sophisticated
    temporal patterns from possibly noisy data. Shape expressions are regular expressions
    with arbitrary (linear, exponential, sinusoidal, etc.) shapes with parameters
    as atomic predicates and additional constraints on these parameters. We equip
    shape expressions with a novel noisy semantics that combines regular expression
    matching semantics with statistical regression. We characterize essential properties
    of the formalism and propose an efficient approximate shape expression matching
    procedure. We demonstrate the wide applicability of this technique on two case
    studies. '

  text: Piecewise Barrier Tubes (PBT) is a new technique for flowpipe overapproximation
    for nonlinear systems with polynomial dynamics, which leverages a combination
    of barrier certificates. PBT has advantages over traditional time-step based methods
    in dealing with those nonlinear dynamical systems in which there is a large difference
    in speed between trajectories, producing an overapproximation that is time independent.
    However, the existing approach for PBT is not efficient due to the application
    of interval methods for enclosure-box computation, and it can only deal with continuous
    dynamical systems without uncertainty. In this paper, we extend the approach with
    the ability to handle both continuous and hybrid dynamical systems with uncertainty
    that can reside in parameters and/or noise. We also improve the efficiency of
    the method significantly, by avoiding the use of interval-based methods for the
    enclosure-box computation without loosing soundness. We have developed a C++ prototype
    implementing the proposed approach and we evaluate it on several benchmarks. The
    experiments show that our approach is more efficient and precise than other methods
    in the literature.
