Interpretation of QSAR Models Based on Random Forest Methods
Molecular Informatics, 2011AbstractA new algorithm for the interpretation of Random Forest models has been developed. It allows to calculate the contribution of each descriptor to the calculated property value. In case of the simplex representation of a molecular structure, contributions of individual atoms can be calculated, and thus it becomes possible to estimate the ...

Improving random forest algorithm by Lasso method
Journal of Statistical Computation and Simulation, 2020The random forest (RF) algorithm is a very practical and excellent ensemble learning algorithm. In this paper, we improve the random forest algorithm and propose an algorithm called ‘post-selection...

Predicting the Accuracy of Ligand Overlay Methods with Random Forest Models
Journal of Chemical Information and Modeling, 2008The accuracy of binding mode prediction using standard molecular overlay methods (ROCS, FlexS, Phase, and FieldCompare) is studied. Previous work has shown that simple decision tree modeling can be used to improve accuracy by selection of the best overlay template.

Density estimation via the random forest method
Communications in Statistics - Theory and Methods, 2017AbstractThe problem of density estimation arises naturally in many contexts. In this paper, we consider the approach using a piecewise constant function to approximate the underlying density. We present a new density estimation method via the random forest method based on the Bayesian Sequential Partition (BSP) (Lu et al., 2013).

A hierarchical method for pedestrian detection with random forests
2014 12th International Conference on Signal Processing (ICSP), 2014Due to many uncontrolled factors, pedestrian detection is one of the most challenging problems in computer vision. In this paper, a fast and accurate hierarchical method for pedestrian detection with random forests is proposed, which can combine holistic information and local information based on image pyramid model.

A fault diagnosis method of engine rotor based on Random Forests
2016 IEEE International Conference on Prognostics and Health Management (ICPHM), 2016Rotor is the main part of the engine, the vibration fault is very common in the process of running, it must be monitored, checked, excluded in a timely manner for improving the reliability of engine and aircraft safety. This paper mainly studies four kinds of rotor fault, including unbalance, misalignment, surge, bearing failure. The frequency spectrum
