A New Noisy Random Forest Based Method for Feature Selection

open access: yesCybernetics and Information Technologies, 2021
Feature selection is an essential pre-processing step in data mining. It aims at identifying the highly predictive feature subset out of a large set of candidate features.

Hybrid Semantic Service Matchmaking Method Based on a Random Forest

open access: yesTsinghua Science and Technology, 2020
Semantic Service Matchmaking (SSM) can be leveraged for mining the most suitable service to accommodate a diversity of user demands. However, existing research on SSM mostly involves logical or non-logical matching, leading to unavoidable false-positive ...

Random Forest variable importance with missing data [PDF]

open access: yes, 2012
Random Forests are commonly applied for data prediction and interpretation. The latter purpose is supported by variable importance measures that rate the relevance of predictors. Yet existing measures can not be computed when data contains missing values.

Monitoring of forest ecosystems in Ireland : FOREM 9 project : final report [PDF]

open access: yes, 2004
Intensive monitoring has been carried out under EC Regulation 3528/86 (project number 8860 IR 001.0) at Ballyhooly, Co. Cork since 1988. In 1991, three new plots (Roundwood, Cloosh and Brackloon) were established (9060IR0030) to give a more ...

AUC-RF: A New Strategy for Genomic Profiling with Random Forest [PDF]

open access: yes, 2011
Objective: Genomic profiling, the use of genetic variants at multiple loci simultaneously for the prediction of disease risk, requires the selection of a set of genetic variants that best predicts disease status.

Perfect sampling methods for random forests [PDF]

open access: yesAdvances in Applied Probability, 2008
A weighted graphGis a pair (V, ℰ) containing vertex setVand edge set ℰ, where each edgee∈ ℰ is associated with a weightWe. A subgraph ofGis a forest if it has no cycles. All forests on the graphGform a probability space, where the probability of each forest is proportional to the product of the weights of its edges.
