內容摘要:
In this talk, we present studies on models and algorithms for groundwater anomaly detection. Specifically, conductivity along with four other surrogates are used for identifying anomaly in groundwater, the one-class support vector machine (SVM) technique is utilized for model training, and real data from “Colorado Water Watch” is used for testing the models and algorithms. Design of code modules in Python will be briefly discussed. Since groundwater contamination rarely happens in reality, we also use data from numerical simulations of flow and transport in porous media to test the anomaly detection code modules. This is a joint work with Ken Carlson, Jianli Gu, and Huishu Li at Colorado State University.
