This paper mainly proposes some improved stochastic gradient descent (SGD) algorithms with a fractional order gradient for the online optimization problem.For three scenarios, including standard learning rate, adaptive gradient learning rate, and momentum learning rate, three new SGD algorithms are designed combining a fractional order Bandana grad
To implement a magneto-optic (MO) nondestructive inspection (MONDI) system for robot-based nondestructive inspections, quantitative evaluations of the presence, locations, shapes, and sizes of defects are required.This capability is essential for training autonomous nondestructive testing (NDT) devices to track material defects and evaluate their s
Zika virus (ZIKV) causes microcephaly and congenital eye disease.The cellular and molecular basis Coffee of congenital ZIKV infection are not well understood.Here, we utilized a biologically relevant cell-based system of human fetal retinal pigment epithelial cells (FRPEs), hiPSC-derived retinal stem cells (iRSCs), and retinal organoids to investig
