Analysis of purely random forests bias [PDF]

open access: yes, 2014
Random forests are a very effective and commonly used statistical method, but their full theoretical analysis is still an open problem. As a first step, simplified models such as purely random forests have been introduced, in order to shed light on the ...

Banzhaf random forests: Cooperative game theory based random forests with consistency [PDF]

open access: yesNeural Networks, 2018
Random forests algorithms have been widely used in many classification and regression applications. However, the theory of random forests lags far behind their applications. In this paper, we propose a novel random forests classification algorithm based on cooperative game theory.

Formal Hypothesis Tests for Additive Structure in Random Forests

open access: yes, 2016
While statistical learning methods have proved powerful tools for predictive modeling, the black-box nature of the models they produce can severely limit their interpretability and the ability to conduct formal inference.

Classification of PolSAR Images by Stacked Random Forests

open access: yesISPRS International Journal of Geo-Information, 2018
This paper proposes the use of Stacked Random Forests (SRF) for the classification of Polarimetric Synthetic Aperture Radar images. SRF apply several Random Forest instances in a sequence where each individual uses the class estimate of its predecessor ...

The Problem of Redundant Variables in Random Forests

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2018
Random forests are currently one of the most preferable methods of supervised learning among practitioners. Their popularity is influenced by the possibility of applying this method without a time consuming pre processing step. Random forests can be used

Analyzing Household Expenditures with Generalized Random Forests

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi
This study investigates the performance of Generalized Random Forest (GRF), which has been known to be useful in understanding heterogeneous treatment effects (HTE) and non-linear relationships in high-dimensional data.

Distributional Random Forests: Heterogeneity Adjustment and Multivariate Distributional Regression

open access: yes, 2021
Random Forests (Breiman, 2001) is a successful and widely used regression and classification algorithm. Part of its appeal and reason for its versatility is its (implicit) construction of a kernel-type weighting function on training data, which can also ...

Time reversal dualities for some random forests

open access: yes, 2014
We consider a random forest $\mathcal{F}^*$, defined as a sequence of i.i.d. birth-death (BD) trees, each started at time 0 from a single ancestor, stopped at the first tree having survived up to a fixed time $T$.

Markov Network Structure Learning via Ensemble-of-Forests Models [PDF]

open access: yes, 2013
Real world systems typically feature a variety of different dependency types and topologies that complicate model selection for probabilistic graphical models.

Oblique random survival forests

open access: yesThe Annals of Applied Statistics, 2019
We introduce and evaluate the oblique random survival forest (ORSF). The ORSF is an ensemble method for right-censored survival data that uses linear combinations of input variables to recursively partition a set of training data. Regularized Cox proportional hazard models are used to identify linear combinations of input variables in each recursive ...
