Abstract. Collecting and more importantly analyzing (big) sets of data
is one of the greatest challenges of our society. One possible tool is
geometrical data analysis, i.e., appropriately embed the data points
in a geometrical object, for example using polynomials. Many problems
in science can be described by polynomial equations. The solution set
of the corresponding polynomial system is referred to as an algebraic
geometrical model for the problem. We will see how geometrical
modeling is used in fields like Kinematics and Biochemistry. Sampling,
i.e., appropriately choosing data points on the model, is a powerful
technique in the study of geometrical models. The key challenge is to
estimate the right density of the data points in order to recover the
shape of the model. An exciting and surprising aspect of the story is
that classical geometrical tools (from early 1900) have shown to be
effective and essential for data analysis.
