A Survey on Graph Neural Networks for Fraud Detection in Ride Hailing Platforms
Kanishka Hewageegana, Janani Harischandra, Nipuna Senanayake +3
This study investigates fraud detection in ride hailing platforms through Graph Neural Networks (GNNs),focusing on the effectiveness of various models. By analyzing prevalent fraud…
First Principle Study of Alkaline Metal Intercalation in Twisted Bilayer Graphene
N K R Perera, K M Abeywickrama, W W P De Silva
The intercalant alkaline metals, Ca, Sr, & Ba, are sources of a periodic perturbation on the bilayer graphene, which leads to the formation of an N-type semiconductors. The twist a…
Effects of Interfacial Distance and Electric Field on Graphene-Silicene Hybrid Structures
K M Abeywickrama, P K D D P Pitigala, W W P De Silva
Graphene is a two-dimensional (2D) semimetal with high mobility in charge carriers due to the existence of Dirac points. Silicene is another promising material, with properties ana…
Computer-aided Interpretable Features for Leaf Image Classification
Jayani P. G. Lakshika, Thiyanga S. Talagala
Plant species identification is time consuming, costly, and requires lots of efforts, and expertise knowledge. In recent, many researchers use deep learning methods to classify pla…
(Four) Dual Plaquette 3D Ising Models
Desmond A. Johnston, R. P. K. C. M. Ranasinghe
A characteristic feature of the 3d plaquette Ising model is its planar subsystem symmetry. The quantum version of this model has been shown to be related via a duality to the X-Cub…
HHCART: An Oblique Decision Tree
D. C. Wickramarachchi, B. L. Robertson, M. Reale +2
Decision trees are a popular technique in statistical data classification. They recursively partition the feature space into disjoint sub-regions until each sub-region becomes homo…
