text: Signal regular expressions can specify sequential properties of real-valued
signals based on threshold conditions, regular operations, and duration constraints.
In this paper we endow them with a quantitative semantics which indicates how
robustly a signal matches or does not match a given expression. First, we show
that this semantics is a safe approximation of a distance between the signal and
the language defined by the expression. Then, we consider the robust matching
problem, that is, computing the quantitative semantics of every segment of a given
signal relative to an expression. We present an algorithm that solves this problem
for piecewise-constant and piecewise-linear signals and show that for such signals
the robustness map is a piecewise-linear function. The availability of an indicator
describing how robustly a signal segment matches some regular pattern provides
a general framework for quantitative monitoring of cyber-physical systems.

text: 'Data-independent Memory Hard Functions (iMHFS) are finding a growing number
of applications in security; especially in the domain of password hashing. An
important property of a concrete iMHF is specified by fixing a directed acyclic
graph (DAG) Gn on n nodes. The quality of that iMHF is then captured by the following
two pebbling complexities of Gn: – The parallel cumulative pebbling complexity
Π∥cc(Gn) must be as high as possible (to ensure that the amortized cost of computing
the function on dedicated hardware is dominated by the cost of memory). – The
sequential space-time pebbling complexity Πst(Gn) should be as close as possible
to Π∥cc(Gn) (to ensure that using many cores in parallel and amortizing over many
instances does not give much of an advantage). In this paper we construct a family
of DAGs with best possible parameters in an asymptotic sense, i.e., where Π∥cc(Gn)
= Ω(n2/ log(n)) (which matches a known upper bound) and Πst(Gn) is within a constant
factor of Π∥cc(Gn). Our analysis relies on a new connection between the pebbling
complexity of a DAG and its depth-robustness (DR) – a well studied combinatorial
property. We show that high DR is sufficient for high Π∥cc. Alwen and Blocki (CRYPTO’16)
showed that high DR is necessary and so, together, these results fully characterize
DAGs with high Π∥cc in terms of DR. Complementing these results, we provide new
upper and lower bounds on the Π∥cc of several important candidate iMHFs from the
literature. We give the first lower bounds on the memory hardness of the Catena
and Balloon Hashing functions in a parallel model of computation and we give the
first lower bounds of any kind for (a version) of Argon2i. Finally we describe
a new class of pebbling attacks improving on those of Alwen and Blocki (CRYPTO’16).
By instantiating these attacks we upperbound the Π∥cc of the Password Hashing
Competition winner Argon2i and one of the Balloon Hashing functions by O (n1.71).
We also show an upper bound of O(n1.625) for the Catena functions and the two
remaining Balloon Hashing functions.'

text: 'We introduce two novel methods for learning parameters of graphical models
for image labelling. The following two tasks underline both methods: (i) perturb
model parameters based on given features and ground truth labelings, so as to
exactly reproduce these labelings as optima of the local polytope relaxation of
the labelling problem; (ii) train a predictor for the perturbed model parameters
so that improved model parameters can be applied to the labelling of novel data.
Our first method implements task (i) by inverse linear programming and task (ii)
using a regressor e.g. a Gaussian process. Our second approach simultaneously
solves tasks (i) and (ii) in a joint manner, while being restricted to linearly
parameterised predictors. Experiments demonstrate the merits of both approaches.'

text: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent asynchronous computation threads. We show
that specifications and correctness proofs for asynchronous programs can be structured
by introducing the fiction, for proof purposes, that intermediate, non-quiescent
states of asynchronous operations can be ignored. Then, the task of specification
becomes relatively simple and the task of verification can be naturally decomposed
into smaller sub-tasks. The sub-tasks iteratively summarize, guided by the structure
of an asynchronous program, the atomic effect of non-atomic operations and the
synchronous effect of asynchronous operations. This structuring of specifications
and proofs corresponds to the introduction of multiple layers of stepwise refinement
for asynchronous programs. We present the first proof rule, called synchronization,
to reduce asynchronous invocations on a lower layer to synchronous invocations
on a higher layer. We implemented our proof method in CIVL and evaluated it on
a collection of benchmark programs.
