Predicting in vitro drug sensitivity using Random Forests

MOTIVATION Panels of cell lines such as the NCI-60 have long been used to test drug candidates for their ability to inhibit proliferation. Predictive models of in vitro drug sensitivity have previously been constructed using gene expression signatures generated from gene expression microarrays. These statistical models allow the prediction of drug response for cell lines not in the original NCI...

Differentially Private Random Decision Forests using Smooth Sensitivity

We propose a new differentially-private decision forest algorithm that minimizes both the number of queries required, and the sensitivity of those queries. To do so, we build an ensemble of random decision trees that avoids querying the private data except to find the majority class label in the leaf nodes. Rather than using a count query to return the class counts like the current state-ofthe-...

Sensitivity and Uncertainty Quantification of Random Distributed Parameter Systems

As simulation continues to replace experimentation in the design cycle, the need to quantify uncertainty in model parameters and its effect on simulation results becomes critical. While intelligent sampling methods, such as sparse grid collocation, have expanded the class of random systems that can be simulated with uncertainty quantification, the statistical characterization of the model param...

Parameter extraction and sensitivity analysis of the discrete RET model for radiowave propagation in inhomogeneous forests

This paper presents a scattering model, based on the Radiative Energy Transfer (RET), adapted to accommodate inhomogeneous vegetation volumes. The model is applied to a real size test forest, formed from 5 different tree species, randomly distributed throughout the test forest. The propagation model relies on four input parameters which were extracted from the different tree types forming the t...

1 Random Forests - - Random Features

Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution for all trees in the forest. The generalization error for forests converges a.s. to a limit as the number of trees in the forest becomes large. The error of a forest of tree classifiers depends on the strength of the individual tre...
