Functional extreme learning machine

open access: yesFrontiers in Computational Neuroscience, 2023
IntroductionExtreme learning machine (ELM) is a training algorithm for single hidden layer feedforward neural network (SLFN), which converges much faster than traditional methods and yields promising performance. However, the ELM also has some shortcomings, such as structure selection, overfitting and low generalization performance.MethodsThis article ...

Time Eigenstates for Potential Functions without Extremal Points

open access: yesEntropy, 2013
In a previous paper, we introduced a way to generate a time coordinate system for classical and quantum systems when the potential function has extremal points.

On the homogeneous extremal function for the standard simplex [PDF]

open access: yes, 2018
In this paper an explicit formula for the homogeneous Siciak’s extremal function is computed in the case of standard simplex in RN. There are discussed some problems related to this result.

Disc formulas for the weighted Siciak-Zahariuta extremal function [PDF]

open access: yes, 2006
We prove a disc formula for the weighted Siciak-Zahariuta extremal function VX,q for an upper semicontinuous function q on an open connected subset X in C n . This function is also known as the weighted Green function with logaritmic pole at infinity and

Robin functions and extremal functions [PDF]

open access: yesAnnales Polonici Mathematici, 2003
Let \(L\) denote the set of plurisubharmonic functions \(u\) on \(\mathbb C^n\) of logarithmic growth, that is \(u(z) \leq \text{log }^+|z|+C\). For a bounded Borel set \(E\) in \(\mathbb C^n\), define \(V_E(z) = \sup\{u(z): u\in L, u\leq 0 \text{ on } E\}\).

The extremal function for K9= minors [PDF]

open access: yesJournal of Graph Theory, 2019
AbstractWe prove the extremal function for minors, where denotes the complete graph with two edges removed. In particular, we show that any graph with vertices and at least edges either contains a minor or is isomorphic to a graph obtained from disjoint copies of and by identifying cliques of size 5.

Revisiting leading quantum corrections to near extremal black hole thermodynamics

open access: yesJournal of High Energy Physics, 2023
Computing the 4D Euclidean path integral to one-loop order we find the large quantum corrections that govern the behavior of a spherically symmetric non-supersymmetric near-extremal black hole at very low temperature.

Aspects of Topological String Theory [PDF]

open access: yes, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

Equivalence of JT gravity and near-extremal black hole dynamics in higher derivative theory

open access: yesJournal of High Energy Physics, 2022
Two derivative Jackiw-Teitelboim (JT) gravity theory captures the near-horizon dynamics of higher dimensional near-extremal black holes, which is governed by a Schwarzian action at the boundary in the near-horizon region.
