The deep learning method based on CNN is used to concatenate all the information together for featur...
Flowchart demonstrating the iterative updating of random forest models.Ben, DeVries
In this study, we propose a weighted quadratic random forest algorithm (WQRF) based on the traditional random forest algorithm combined with data characteristics. By calculating the F-measure of each tree and introducing weighted voting, the WQRF can solve the problem of unbalanced data and rank ...
We identified the main variables for machine learning Random Forest (RF), generating a predictive model that can estimate patient mortality/morbidity according to the following groups: (1) IS + ICH, (2) IS, and (3) ICH. A total of 6022 patients were included: 4922 (mean age 71.9...
we used the random forest prediction model to score unconfirmed lncRNA-disease pairs. The larger the score of an lncRNA-disease pair, the more likely the lncRNA and the disease are associated. It should be noted that two main parameters in random forest algorithm, themtryand thentree, were...
Finally, the model of RFMDA had a good generalization ability, which benefitted from utilizing an unbiased estimator for generalization error in the Random Forest algorithm and that the parameters of Random Forest were easy to select. However, some limitations still exist in the model of RFMDA....

(GEE) platform. Additionally, the study incorporated the random forest (RF) algorithm. This study aimed to generate continuous LULC maps for 2014 and 2020 for the Shrirampur area of Maharashtra, India. A novel multiple composite RF approach based on LULC classification was utilized to generate ...
(e.g., a random forest of regression trees), or some other pose estimation algorithm. An inverse of the translation and rotation applied to the set of image points could then be applied to a pose estimate generated by such a process, so as to generate an estimate of the pose of the ...
First, RFLDA predicts LDA using the supervised random forest algorithm, which requires both positive and negative samples. However, it is almost unrealistic to obtain the reliable negative samples for LDA prediction. The method of randomly selecting negative samples may influ- ence the prediction ...
