Create a C++ class drawing a dendrogram in pure OpenGL (2d). A sketch of the desired result is attached. Assume an existing opengl context and a viewport/modelview setup for 2d drawing. (Maybe use a simple opengl skeleton program on your preferred platform to test this class). The C++ class gets the following inputs: 1. A binary tree of nodes: - each node has a member "value" which specifies the distance (w.r.t. the x-axis) to the previous node. This is basically the length of the horizontal lines. Depending on the size of the viewport it might be neccessary to scale this values in order to fill the entire drawing area with the chart. E.g. the values could be in a range of 0 to 1, but the viewport is e.g. 1280x1024. Then a sensible scaling of the values to pixel units should be performed - the leaf nodes represent the final nodes, drawn as boxes on the very right In these leave nodes a text and a color can be specified which specifies the c...

quite simply, we want to predict the risk of customer credit default. This is a new project for us, so we want to have someone who has done this before and can also tell us what are good data sets to use, what training data corpus to use, etc. Basically, this should be a start to finish proof-of-concept project from the side of the freelancer, who will also teach us how to work with the code. Our team has top-shot programmers, but are not experts in machine learning or recommender systems. Preferred: Scipy/Numpy. Also OK with R, but will prefer the former. Since this is a proof-of-concept project, we would like to work with fixed budgets.
