Abstract: It has been reported that training deep neural networks is more difficult than training shallow neural networks. Hinton et al. proposed deep belief networks with a learning algorithm that trains one layer at a time. A…

Abstract: We study the singular points of the differential systems of the form $$\dot{x}= x+P(x,y), \ \dot{y}=y+Q(x,y)$$x˙=x+P(x,y),y˙=y+Q(x,y) where P(x, y) and Q(x, y) are homogeneous polynomials of degree n.

Abstract: Recent work by Serfaty and Serra give a formula for the velocity of the free boundary of the obstacle problem at regular points [Serfaty-Serra 2018], and much older work by King, Lacey, and Vazquez gives…

DOI: 10.1016/j.jde.2020.07.022
Abstract: Abstract Using the Euler-Jacobi formula there is a relation between the singular points of a polynomial vector field and their topological indices. Using this formula we obtain the configuration of the singular points together with…

DOI: 10.1109/tifs.2020.3036803
Abstract: Fingerprint pose estimation is a challenging problem since the pose is not defined by salient anatomical features and fingerprint images usually suffer from noise and small area. In this article, we proposed a method for…

Abstract: Most methods for singular points detection usually depend on the orientation fields of fingerprints, which cannot achieve reliable and accurate detection of poor quality fingerprints. In this study, a new method for fingerprint singular points…
