Optimization and Application of Fuzzy Neural Network

open access: yesJournal of Harbin University of Science and Technology, 2020
In order to improve the generalization ability,convergence speed and reduce the error of the fuzzyneural network,the method of using momentum gradient descent algorithm and RMSprop optimization algorithm to optimize the fuzzy neural network is proposed ...

Generalized second-order partial derivatives of 1/r

open access: yes, 2010
The generalized second-order partial derivatives of 1/r, where r is the radial distance in 3D, are obtained using a result of the potential theory of classical analysis.

Regular and semi-regular polytopes. II

open access: yesMathematische Zeitschrift, 1940
[For part I see the review above.] The first section summarizes Part I, giving particular attention to the 3-dimensional point groups. The second section establishes subgroup relationships among the various irreducible reflection groups in 4 dimensions: 5 finite and 5 infinite.

Neuroinflammation in GAD65 Antibody‐Associated Epilepsy Measured Using [18F]DPA‐714 PET/MRI

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The timing for initiating immunotherapy in patients with glutamic acid decarboxylase 65 (GAD65) antibody‐associated epilepsy is a challenge. We used the translocator protein radioligand [18F]DPA‐714 and PET to evaluate brain microglial activation.

Global in time well-posedness of a three-dimensional periodic regularized Boussinesq system

open access: yesDemonstratio Mathematica
Global in time weak solution to a regularized periodic three-dimensional Boussinesq system is proved to exist in energy spaces. This solution depends continuously on the initial data. In particular, it is unique.

A Regularized Interface Model for Simulating the Response of Adhesive Joints

open access: yesAnnals of "Dunarea de Jos" University of Galati, Fascicle XII, Welding Equipment and Technology
A regularized interface damage model is presented grounded on the cohesive-zone concept. This is obtained using a gradient-based formulation, which is equivalent to the introduction of the laplacian of a scalar damage field into the threshold function of

Convex regularization of discrete-valued inverse problems

open access: yes, 2017
This work is concerned with linear inverse problems where a distributed parameter is known a priori to only take on values from a given discrete set.

Regular and completely regular differential operators [PDF]

open access: yesMathematical Notes, 2007
We define the concept of completely regular ordinary differential operators and give various criteria for operators to belong to this class. We give also criteria for Birkhof regularity of ordinary differential operators in terms of the growth of the Green function and basis property.

Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Indoor Building Reconstruction from Occluded Point Clouds Using Graph-Cut and Ray-Tracing

open access: yesApplied Sciences, 2018
Despite the increasing demand of updated and detailed indoor models, indoor reconstruction from point clouds is still in an early stage in comparison with the reconstruction of outdoor scenes.
