Utility metric for unsupervised feature selection [PDF]
PeerJ Computer Science, 2021 Feature selection techniques are very useful approaches for dimensionality reduction in data analysis. They provide interpretable results by reducing the dimensions of the data to a subset of the original set of features.

Multistability and anomalies in oscillator models of lossy power grids
Nature Communications, 2022 Dissipatively coupled oscillators, describing lossy flows in power grids, are challenging to analyze due to asymmetry of couplings. Here, Delabays et al.

Signal-to-Interference-Plus-Noise Ratio Based Optimization for Sound Zone Control
IEEE Open Journal of Signal Processing, 2023 Sound zone control is posed as an optimization problem where finite impulse response control filters are jointly optimized for low transmit power, while maintaining a sufficiently high signal-to-interference-plus-noise ratio (SINR) in all zones.

Degenerate dynamical systems [PDF]
Journal of Mathematical Physics, 2001 Dynamical systems, whose symplectic structure degenerates, becoming noninvertible at some points along the orbits, are analyzed. It is shown that for systems with a finite number of degrees of freedom, like in classical mechanics, the degeneracy occurs on domain walls that divide phase space into nonoverlapping regions, each one describing a ...

Dynamics of Multimodal Families of m-Modal Maps
Complexity, 2022 In this work, we introduce families of multimodal maps based on logistic map, i.e., families of m-modal maps are defined on an interval I⊂ℝ, which is partitioned into non-uniform subdomains, with m∈ℕ.

Complexified dynamical systems [PDF]
Journal of Physics A: Mathematical and Theoretical, 2007 Many dynamical systems, such as the Lotka-Volterra predator-prey model and the Euler equations for the free rotation of a rigid body, are PT symmetric. The standard and well-known real solutions to such dynamical systems constitute an infinitessimal subclass of the full set of complex solutions.
