Description
In this course, four machine learning supervised classification based techniques used with remote sensing and geospatial resources data to predict two different types of applications: Project 1: Data of Multi-labeled target prediction via multi-label classification (multi class problem). Target (Y) that has 3 labeled classes (instead of Numbers): Names, description, ordinal value (small, large, X-large)..Multiple output maps. Like:Increase specific type of species in certain areas and its relationship with surrounding conditions.Air pollution limits prediction (Good, moderate, unhealthy, Hazardous..)Complex diseases types: potential risk factors and their effects on the disease are investigated to identify risk factors that can be used to develop prevention or intervention strategies.Course application: Prediction of concentration of particulate matter of less than 10 m diameter (PM10)This project was published as research articles using similar materials and with major part of analysis (with slight modification to the code). "Demystifying uncertainty in PM10 susceptibility mapping using variable drop-off in extreme-gradient boosting (XGB) and random forest (RF) algorithms" in Environmental Science and Pollution Research journal.Project 2: Data of Binary labeled target prediction. Target with 2 classes: Yes and No, Slides and No slide, Happened Not happened, Contaminated- Clean.Flooded areas and it contribution factors like topographic and climate data.Climate change related consequences and its dragging factors like urban heat islands and it relationship with land uses.Oil spills: polluted and non polluted.Course application: Landslide susceptibility mapping in prone area.If you are previously enrolled in my previous course using ANN, then you have the chance to compare the outcomes, as we used the same landslide data here.Eventually, all the measured data (training and testing), were used to produce the prediction map to be used in further GIS analysis or directly to be presented to decision makers or writing research article in SCI journals.This course considered the most advanced, in terms of analysis models and output maps that successfully invested in the (1) machine learning algorithm and geospatial domains; (2) free available data of remote sensing in data scarce environment.
