Classification methods have been developed considering known functional links between features. For example, a variant of the Random Forest method has been proposed where the feature sub-sampling was conducted according to spatial information of genes on a known functional network10.Objective functions of...
However, here there is an example where the absolute scale drastically affects the performance of random forest. Just by multiplying the response by a small number, the performance drastically falls. I am pretty sure this is associated to numerical errors, but notice that the scale factor is not...
The objectives of this study were to: (1) retrieve a complete long-term turbidity series from Landsat images from 1990 to 2020 using random forest; (2) assess the spatiotemporal variations in turbidity for different water surface types in the YRDR during 1990–2020; and (3) explore the ...
With this background, the current study presents ‘Proteus’, a random forest classifier that predicts the likelihood of a residue undergoing a disorder-to-order transition upon binding to a potential partner protein. The prediction is based on features that can be calculated using the amino acid...
One of the main advantages of using bagging when applying a random forest algorithm isvariance reductionof the model. For example, when a single decision tree is used, it is very prone to overfitting and can be sensitive to the noise in the data. However, bootstrap aggregation reduces this ...
Because a random forest can be used for both classification and regression tasks, it is very versatile. It can easily handle binary and numerical features as well as categorical ones, with no need for transformation or rescaling. Unlike almost every other model, it is incredibly efficient with ...

The proposed automatic evaluation through the random forest algorithm has outperformed many assessments compared with the expert evaluation. The peaks in the graph represent the evaluation value for the specific assessment for the students of both grades. The numerical representation of the figure is ...
Introduction As the name suggests, random forest models basically contain an ensemble of decision tree models, with each decision tree predicting the same response variable. The response may be categorical, in which case being a classification prob...
