Coalescent Random Forests
Various enumerations of labeled trees and forests, including Cayley's formula n for the number of trees labeled by [n], and Cayley's multinomial expansion over trees, are derived from the following coalescent construction of a sequence of random forests (Rn , Rn&1 , ..., R1) such that Rk has uniform distribution over the set of all forests of k rooted trees labeled by [n]. Let Rn be the trivial...
متن کاملCoalescent Random Walks on Graphs
Inspired by coalescent theory in biology, we introduce a stochastic model called ”multi-person simple random walks” or “coalescent random walks” on a graph G. There are any finite number of persons distributed randomly at the vertices of G. In each step of this discrete time Markov chain, we randomly pick up a person and move it to a random adjacent vertex. To study this model, we introduce the...
متن کامل1 Random Forests - - Random Features
Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution for all trees in the forest. The generalization error for forests converges a.s. to a limit as the number of trees in the forest becomes large. The error of a forest of tree classifiers depends on the strength of the individual tre...
متن کاملMondrian Forests: Efficient Online Random Forests
Ensembles of randomized decision trees, usually referred to as random forests, are widely used for classification and regression tasks in machine learning and statistics. Random forests achieve competitive predictive performance and are computationally efficient to train and test, making them excellent candidates for real-world prediction tasks. The most popular random forest variants (such as ...
متن کاملRandom Composite Forests
We introduce a broad family of decision trees, Composite Trees, whose leaf classifiers are selected out of a hypothesis set composed of p subfamilies with different complexities. We prove new data-dependent learning guarantees for this family in the multi-class setting. These learning bounds provide a quantitative guidance for the choice of the hypotheses at each leaf. Remarkably, they depend o...
