Higher order PCA-like rotation-invariant features for detailed shape descriptors modulo rotation
Jarek Duda
PCA can be used for rotation invariant features, describing a shape with its covariance matrix approximating shape by ellipsoid, allowing for r…
Experimental estimation of Asymmetry of Radiation for Wheeler-Feynman theory for gravitational waves
Jarek Duda
Maxwell equations mathematically allow both retarded and advanced solutions, also their convex combinations. While Wheeler-Feynman absorber theory assumed their symmetric contribut…
Adaptive stable distribution and Hurst exponent by method of moments moving estimator for nonstationary time series
Jarek Duda
Nonstationarity of real-life time series requires model adaptation. In classical approaches like ARMA-ARCH there is assumed some arbitrarily chosen dependence type. To avoid their…
Time crystal kinks by curvature coupling as toy model for mechanism of oscillations propelled by mass, like observed for electron and neutrinos
Jarek Duda
Dirac equation requires energy of resting particle, leading to some its evolution - periodic process of frequency, literally propelled by…
Testing stimulated emission photon directions
Jarek Duda
While naively laser only causes excitation of external target, e.g. Rabi cycle, STED microscopy or ASE/SASE/SSA demonstrate it can also stimulate its deexitation, however, under un…
Biology-inspired joint distribution neurons based on Hierarchical Correlation Reconstruction allowing for multidirectional propagation of values and densities
Jarek Duda
Recently a million of biological neurons (BNN) has turned out better from modern RL methods in playing Pong~\cite{RL}, reminding they are still qualitatively superior e.g. in learn…
Simple inexpensive vertex and edge invariants distinguishing dataset strongly regular graphs
Jarek Duda
While standard Weisfeiler-Leman vertex labels are not able to distinguish even vertices of regular graphs, there is proposed and tested family of inexpensive polynomial time vertex…
Phase space maximal entropy random walk: Langevin-like ensembles of physical trajectories
Jarek Duda
As written by statistician George Box "All models are wrong, but some are useful", standard diffusion derivation or Feynman path ensembles use nonphysical infinite velocity/kinetic…
Extracting individual variable information for their decoupling, direct mutual information and multi-feature Granger causality
Jarek Duda
Working with multiple variables they usually contain difficult to control complex dependencies. This article proposes extraction of their individual information, e.g. $\overline{X|…
P?=NP as minimization of degree 4 polynomial, integration or Grassmann number problem, and new graph isomorphism problem approaches
Jarek Duda
While the P vs NP problem is mainly approached form the point of view of discrete mathematics, this paper proposes reformulations into the field of abstract algebra, geometry, four…
