2009 journal article

A Model-Based Ensembling Approach for Developing QSARs

JOURNAL OF CHEMICAL INFORMATION AND MODELING, 49(8), 1857–1865.

By: Q. Zhang n, J. Hughes-Oliver n & R. Ng  n

MeSH headings : Computer Simulation; Models, Chemical; Quantitative Structure-Activity Relationship
TL;DR: This work extends the application of ensemble methods to include cases of imbalance of class membership and to more adequately assess model output to propose an ensemble method called MBEnsemble that automatically determines the appropriate tuning parameters to provide reliable predictions and maximize the F-measure.

JOURNAL OF ENVIRONMENTAL QUALITY, 37(5), 1862–1874.

By: W. Renwick*, M. Vanni *, Q. Zhang n & J. Patton*

MeSH headings : Agriculture / trends; Ammonia / chemistry; Environmental Monitoring; Indiana; Midwestern United States; Nitrates / chemistry; Ohio; Phosphorus / chemistry; Rivers / chemistry; Time Factors; Water / chemistry; Water Pollutants, Chemical; Water Supply / analysis; Water Supply / standards
TL;DR: Trends in total N and P are strongly tied to trends in NO(3), SRP, and SS and indicate that total P is declining, whereas total N is not, in three Corn Belt streams over the 13-yr period. (via Semantic Scholar)
