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…
FFORMPP: Feature-based forecast model performance prediction
Thiyanga S. Talagala, Feng Li, Yanfei Kang
This paper introduces a novel meta-learning algorithm for time series forecast model performance prediction. We model the forecast error as a function of time series features calcu…
The Impact of Project Management in Virtual Environment: A Software Industry Perspective
Bashini Jeewanthi Gamage
Virtual team in a project within an Organization could achieve optimize project performance by acquiring appropriate human resources, coordination, communication and regular perfor…
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…
Potts Models with Invisible States on General Bethe Lattices
N. Ananikian, N. Sh. Izmailyan, D. A. Johnston +2
The number of so-called invisible states which need to be added to the q-state Potts model to transmute its phase transition from continuous to first order has attracted recent att…
Potts Models with (17) Invisible States on Thin Graphs
D. A. Johnston, R. P. K. C. M. Ranasinghe
The order of a phase transition is usually determined by the nature of the symmetry breaking at the phase transition point and the dimension of the model under consideration. For i…
The Dual Gonihedric 3D Ising Model
D. A. Johnston, R. P. K. C. M. Ranasinghe
We investigate the dual of the kappa=0 Gonihedric Ising model on a 3D cubic lattice, which may be written as an anisotropically coupled Ashkin-Teller model. The original kappa=0 Go…
The Gonihedric Ising Model and Glassiness
D. A. Johnston, A. Lipowski, Ranasinghe P. K. C. Malmini
The Gonihedric 3D Ising model is a lattice spin model in which planar Peierls boundaries between + and - spins can be created at zero energy cost. Instead of weighting the area of…
The Information Geometry of the Ising Model on Planar Random Graphs
W. Janke, D. A. Johnston, Ranasinghe P. K. C. Malmini
It has been suggested that an information geometric view of statistical mechanics in which a metric is introduced onto the space of parameters provides an interesting alternative c…
Decorating Random Quadrangulations
D. A. Johnston, R. P. K. C. Malmini
On various regular lattices (simple cubic, body centred cubic..) decorating an edge with an Ising spin coupled by bonds of strength L to the original vertex spins and competing wit…
Gonihedric Ising Actions
D. A. Johnston, R. P. K. C. Malmini
We discuss a generalized Ising action containing nearest neighbour, next to nearest neighbour and plaquette terms that has been suggested as a potential string worldsheet discretiz…
