Through a novel application of random forest modelling to spoor data from 16 mammal species, this study highlights the importance of adopting a multi‐scale, multi‐species approach for decision‐making processes that depend on understanding wildlife distributions and habitat associations, such as ...
Two real datasets were analysed to demonstrate the usefulness of RF for overdispersed data modelling. Goodness-of-fit statistics such as root mean square error (RMSE) and biases were used to determine RF accuracy and validity. Results revealed that the number of variables to be randomly selected...

However, when there’s a robust number of decision trees in a random forest, the classifier won’t overfit the model since the averaging of uncorrelated trees lowers the overall variance and prediction error. Provides flexibility: Since random forest can handle both regression and classification task...
In this paper we propose two ways to deal with the imbalanced data classification problem using random forest. One is based on cost sensitive learning, and the other is based on a sampling technique. Performance metrics such as precision and recall, false positive rate and false negative rate,...

Modelling of physical and physiological processes controlling primary production and population dynamics of cyanobacteria Random forest models were constructed to predict benthic irradiance for two sites in Moreton Bay. The importance of wind speed and direction in the benthic... M Kehoe - 《Cylindrospe...
New concept was defined to evaluate the damages of the underground structure (US).New model was firstly used to predict the seismic performance levels of US.A quantification system for the seismic damage of shallow buried US was advanced.IDR was suitable to describe the seismic damage of shallow...
Subsequently, the random forest (RF) model was used to create a landslide susceptibility map with original and optimized factors. The resultant hybrid models GeoDetector-RF and RFE-RF were evaluated and compared by the area under the receiver operating characteristic curve (AUC) and accuracy. The ...
