WebI am training a random forest model using the sk-learn library, for a binary classification task. For some reason, when I set the max_depth parameter to 1, the model has an average 90% accuracy on predicting positive labels (sensitivity), but only around 30% when predicting negative class labels (specificity). WebApr 14, 2024 · Machine learning methods included random forest, random forest ranger, gradient boosting machine, and support vector machine (SVM). Results. SVM showed the best performance in terms of accuracy, kappa, sensitivity, detection rate, balanced accuracy, and run-time; the area under the receiver operating characteristic curve was also quite …

WebThe first component should be the minimum of the desired x-axis range, while the second component should be the maximum of the desired x-axis range. If NULL (default), the range is calculated from the Data (min,max) of sensitivity. sp.axis. x-axis range for specificity, based on a vector of 2 components. WebApr 15, 2024 · This study aimed at (i) developing, evaluating and comparing the performance of support vector machines (SVM), boosted regression trees (BRT), random forest (RF) and logistic regression (LR) models in mapping gully erosion susceptibility, and (ii) determining the important gully erosion conditioning factors (GECFs) in a Kenyan semi-arid landscape. … names from godfather
