The interpretability aims at helping people understand internal operation principles and decision principles of models, so as to improve models' credibility. However, research on the interpretability of ML models such as Random Forest (RF) is still in the infant stage. ...

(a) shows the ROC curve for the first wave: the random forest generally achieves better performance. (b) shows the ROC curve for the second wave: in this case, all models obtain similar results. All results have been obtained using leave-one-out validation. The positive class is considered...
While SHAP can explain the output of any machine learning model, we have developed a high-speed exact algorithm for tree ensemble methods (see our Nature MI paper). Fast C++ implementations are supported for XGBoost, LightGBM, CatBoost, scikit-learn and pyspark tree models: import xgboost import...

The software equivalency of this would be to create a 3 dimensional representation of objects and create a linear-algebra algorithm that can define the statistical probability that any given shape is within a certain degree of exclusion a matrix representation of the target shape (area) of the 3...

We used a random forest algorithm in combination with phylogenetic trait imputation to fill gaps in the trait data and not omit missing data (Penone et al. 2014). To strengthen the predictive power of the model, we used the missForest::misForest() function (Stekhoven 2022) and phylogenetic ...
Briefly explain the differences and similarities between random forest and decision trees. How do we randomize twice when implementing the random forest algorithm? Please review the following memo and note at least four instances where it could ...
TreeSHAP is an algorithm to compute SHAP values for tree ensemble models such as decision trees, random forests, and gradient boosted trees in a polynomial-time proposed by Lundberg et. al (2018)¹. The algorithm allows us to reduce the complexity from O(TL2^M)to O(TLD^2) (T = numb...
