Categorisation of Machine Learning algorithms for business applications

Practicing the scientific approach to the data exploration one should know at what extent certain method can be applied. Neural Nets are futile for the stock market's predictions. Monte-Carlo algorithms couldn't offer much help either, and poorly implemented Random Forest algorithm can literally ruin your vacation in South-East Asia, especially if it was implemented by NSA. In this article we will briefly introduce machine learning methods classification and see how they are relevant to the different lines of business. From the cradle to the grave, we are making decisions - from our first decision to attract mother's attention to one of our last decisions when asking the doctor for pain treatment.
