Mastering Scala Machine Learning

Basic correlations

You probably noticed that detecting correlations from contingency tables is hard. Detecting patterns takes practice, but many people are much better at recognizing the patterns visually. Detecting actionable patterns is one of the primary goals of machine learning. While advanced supervised machine learning techniques that will be covered in Chapter 4, Supervised and Unsupervised Learning and Chapter 5, Regression and Classification exist, initial analysis of interdependencies between variables can help with the right transformation of variables or selection of the best inference technique.

Multiple well-established visualization tools exist and there are multiple sites, such as http://www.kdnuggets.com, which specialize on ranking ...
