Bayesian Diagnostics for Test Design and Analysis

Silva, R. M.; Guan, Y.; Swartz, T. B. (Czech University of Life Sciences Prague, 2017-07)

This paper attempts to bridge the gap between classical test theory and item response theory. It is demonstrated that the familiar and popular statistics used in classical test theory can be translated into a Bayesian ...

HHCART: An Oblique Decision Tree

Wickramarachchi, D.C.; Robertson, B.L.; Reale, M.; Price, C.J.; Brown, J. (Elsevier, 2015)

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 homogeneous with respect to a particular class. ...

Design of a Low-cost Autonomous Mobile Robot

Jinasena, Kasun K.; Meegama, Ravinda G.N. (2016-05-13)

Detection of obstacles during navigation of a mobile robot is considered difficult due to varying nature in terms of size, shape and location of the obstacle as well as ambient light that interferes with infra-red (IR) ...

A Comparison of Clustering Algorithms in Categorizing Economic Events Based on the Behavior of Exchange Rates

Pathberiya, H.A.; Hansen, L.L.; Tilakaratne, C.D.; Lokupitiya, R.S. (2016-04-04)

Cluster analysis is used to identify dissimilar subgroups of objects out of a set of objects based on a combination of rules. In the light of cluster analysis, it is possible to treat dissimilar individuals in an ...
