چکیده

Abstract The present study aims to develop an efficient predictive model for groundwater contamination using Multivariate Logistic Regression (MLR) and Random Forest (RF) algorithms. Contamination by ammonia is recorded many authors at Sohag Governorate, Egypt attributed urban growth, agricultural, industrial activities. Thirty-two samples representing the Quaternary aquifer are collected analyzed major cations (Ca, Mg, Na), ammonia, nitrate, phosphate, heavy metals. Lead, magnesium, iron, zinc variables used test with which as index contamination. Spatial distribution maps statistical analyses show a strong correlation of lead magnesium whereas iron less correlation. For model, data divided into 70% training 30% testing subsets. performance evaluated classification reports, confusion matrix. Results (1) high RF accuracy 93% (2) MLR increased from 70 83% when “SOLVER” “C” parameters modified. helps identify contaminated zones area proved usefulness machine learning models prediction concentration.

Random forest versus logistic regression: a large-scale benchmark experiment

The Random Forest (RF) algorithm for regression and classification has considerably gained popularity since its introduction in 2001. Meanwhile, it has grown to a standard classification approach competing with logistic regression in many innovation-friendly scientific fields. In this context, we present a large scale benchmarking experiment based on 260 real datasets comparing the prediction p...

Modeling Anthropogenic Fire Occurrence in the Boreal Forest of China Using Logistic Regression and Random Forests

Frequent and intense anthropogenic fires present meaningful challenges to forest management in the boreal forest of China. Understanding the underlying drivers of human-caused fire occurrence is crucial for making effective and scientifically-based forest fire management plans. In this study, we applied logistic regression (LR) and Random Forests (RF) to identify important biophysical and anthr...
