Variable Importance Clouds: A Way to Explore Variable Importance for the Set of Good Models

open access: yesCoRR, 2019
Variable importance is central to scientific studies, including the social sciences and causal inference, healthcare, and other domains. However, current notions of variable importance are often tied to a specific predictive model. This is problematic: what if there were multiple well-performing predictive models, and a specific variable is important ...

Evaluation of Four Supervised Learning Methods for Benthic Habitat Mapping Using Backscatter from Multi-Beam Sonar

open access: yesRemote Sensing, 2012
An understanding of the distribution and extent of marine habitats is essential for the implementation of ecosystem-based management strategies. Historically this had been difficult in marine environments until the advancement of acoustic sensors.

Climatic Drivers of Plant Species Distributions Across Spatial Grains in Southern Africa Tropical Forests

open access: yesFrontiers in Forests and Global Change, 2019
Understanding the importance of climate in determining species distribution and how it might change as a function of spatial grain size is a vital issue for species distribution modeling (SDM), yet it is often not accounted for in models and has not been

Variable selection with Random Forests for missing data [PDF]

open access: yes, 2013
Variable selection has been suggested for Random Forests to improve their efficiency of data prediction and interpretation. However, its basic element, i.e.

PUBO$$_i$$: A Tunable Benchmark with Variable Importance

open access: yes, 2022
In this work, we present the benchmark generator PUBOi, Polynomial Unconstrained Binary Optimization, that combines subproblems to create instances of pseudo-boolean optimization problems. Any mono-objective pseudoboolean functions including existing classical optimization problems can be expressed with Walsh functions. The benchmark generator can tune

Importance of understanding variable and transient energy demand in large multi-product industrial plants for process integration [PDF]

open access: yes, 2011
There have been some news releases claiming that Professor Henle in Germany has found the chemical identity of UMF, and that in future chemical analysis will be used instead of assays of antibacterial activity to indicate the level of UMF in manuka honey.
