BMC Public Health, 2017 Background As service provision and patient behaviour varies by day, healthcare data used for public health surveillance can exhibit large day of the week effects. These regular effects are further complicated by the impact of public holidays.

SGD learning on neural networks: leap complexity and saddle-to-saddle dynamics [PDF]
Annual Conference Computational Learning Theory, 2023 We investigate the time complexity of SGD learning on fully-connected neural networks with isotropic data. We put forward a complexity measure -- the leap -- which measures how"hierarchical"target functions are.

Accurate Estimate of the Advantage of Impossible Differential Attacks
IACR Transactions on Symmetric Cryptology, 2017 Impossible differential attacks, which are taking advantage of differentials that cannot occur, are powerful attacks for block cipher primitives. The power of such attacks is often measured in terms of the advantage — number of key-bits found during the ...

A Multi-Phase Method for Euclidean Traveling Salesman Problems
Axioms, 2022 The Traveling Salesman Problem (TSP) aims to find the shortest tour for a salesman who starts and ends in the same city and visits the remaining n−1 cities exactly once.

Fractional-Order Discrete-Time SIR Epidemic Model with Vaccination: Chaos and Complexity
Mathematics, 2022 This research presents a new fractional-order discrete-time susceptible-infected-recovered (SIR) epidemic model with vaccination. The dynamical behavior of the suggested model is examined analytically and numerically.

Towards a Unified Framework of Matrix Derivatives
IEEE Access, 2018 The need of processing and analyzing massive statistics simultaneously requires the derivatives of matrix-to-scalar functions (scalar-valued functions of matrices) or matrix-to-matrix functions (matrixvalued functions of matrices).

COMPLEXITY, TIME AND MUSIC [PDF]
Advances in Complex Systems, 2010 The concept of complexity as considered in terms of its algorithmic definition proposed by G. J. Chaitin and A. N. Kolmogorov is revisited for the dynamical complexity of music. When music pieces are cast in the form of time series of pitch variations, concepts of dynamical systems theory can be used to define new quantities such as the dimensionality

Timed Parity Games: Complexity and Robustness [PDF]
Logical Methods in Computer Science, 2008 We consider two-player games played in real time on game structures with clocks where the objectives of players are described using parity conditions. The games are \emph{concurrent} in that at each turn, both players independently propose a time delay and an action, and the action with the shorter delay is chosen.
