Often in machine learning tasks, you have multiple possible labels for one sample that are not mutually exclusive. This is called a multi-class, multi-label classification problem. Obvious suspects are image classification and text classification, where a document can have multiple topics. Both of these tasks are well tackled by neural networks. A famous python framework for working with neural networks is keras. We will discuss how to use keras to solve this problem. Read more

In this post we will introduce multivariate adaptive regression splines model (MARS) using python. This is a regression model that can be seen as a non-parametric extension of the standard linear model. The multivariate adaptive regression splines model MARS builds a model of the from $$f(x) = \sum_{i=0}^k c_i B_i(x_i),$$ where $x$ is a sample vector, $B_i$ is a function from a set of basis functions (later called terms) and $c_i$ the associated coefficient.
