Advanced Methods and Topics of Regressionere, the emphasis was on simple formulation that is easy to understand. However, machine learning regression offers many more methods and tools than already introduced. To this end, we will introduce model formulations that can easily be generalized and that additionally can also be efficiently impl

Supervised Classificationlearning, and the goal is to learn how to sort data into different categories. While the ML methods are quite different from those used for regression, the fundamental aspects of learning are similar. In this chapter, we start with a detailed introduction of classification based on intuitive, rule-b

Unsupervised Learninglearning only consist of numerical features but do not contain any target values. In this chapter, we discuss two large classes of methods: clustering methods that try to find data points that “have something in common” and dimensionality reduction methods, which transform the data into another repr

This chapter introduces some of these techniques and covers topics ranging from feature engineering and feature importance, training, testing,

In the process of organizing to do this, I realized that the research in this field had produced a need for an updated review of the underlying paradigms. This need had arisen because of the special properties of the samarium-neodymium isotopic sy

Oceanic basalts present the possibility of applying the isotopic data for this purpose in a relatively straightforward way because there is little likelihood that the magmas are modified by contamination with old continental crust between the t
