Random Hyperplane Search Trees

open access: yesSIAM Journal on Computing, 2009
Summary: A hyperplane search tree is a binary tree used to store a set \(S\) of \(n\) \(d\)-dimensional data points. In a random hyperplane search tree for \(S\), the root represents a hyperplane defined by \(d\) data points drawn uniformly at random from \(S\).

Search for the smallest random forest [PDF]

open access: yesStatistics and Its Interface, 2009
Random forests have emerged as one of the most commonly used nonparametric statistical methods in many scientific areas, particularly in analysis of high throughput genomic data. A general practice in using random forests is to generate a sufficiently large number of trees, although it is subjective as to how large is sufficient.

A Comparative Analysis of Hyperparameter Tuned Stochastic Short Term Load Forecasting for Power System Operator

open access: yesEnergies, 2023
Intermittency in the grid creates operational issues for power system operators (PSO). One such intermittent parameter is load. Accurate prediction of the load is the key to proper planning of the power system.
