Temporal evolution of generalization during learning in linear networks [PDF]

open access: yes, 1991
We study generalization in a simple framework of feedforward linear networks with n inputs and n outputs, trained from examples by gradient descent on the usual quadratic error function.

Image Navigation for FY-4A Lightning Mapping Imager

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Navigation of images from lightning mapping instruments in geostationary orbits is very important for data applications. However, few scientific peer-reviewed papers have been reported, except a few works in the prelaunch tests.

Human activity recognition making use of long short-term memory techniques [PDF]

open access: yes, 2019
The optimisation and validation of a classifiers performance when applied to real world problems is not always effectively shown. In much of the literature describing the application of artificial neural network architectures to Human Activity ...

Modal testing and modelling the dynamic characteristics of a plate with bolted joints

open access: yesJournal of Mechanical Engineering and Sciences, 2021
Modelling the dynamic characteristics of the bolted joints in a complex assembled structure with a high accuracy is very challenging due to the assumptions and uncertainties in the input data of the FE model.

Predicting blunt cerebrovascular injury in pediatric trauma: Validation of the Utah Score [PDF]

open access: yes, 2017
Risk factors for blunt cerebrovascular injury (BCVI) may differ between children and adults, suggesting that children at low risk for BCVI after trauma receive unnecessary computed tomography angiography (CTA) and high-dose radiation.

Numerical And Experimental Investigations of Nonlinearity Behaviour In A Slender Cantilever Beam

open access: yesMATEC Web of Conferences, 2018
Nonlinear problem is always occur in slender structures that are usually characterized by large displacements and rotations but small strains. Linear design assumption could lead to premature failure if the structure behaves nonlinearly.
