Solved – Visualizing high dimensional data

data visualizationdimensionality reductionMATLABpython

I have samples of two classes which are vectors in high dimensional space and I want to plot them in 2D or 3D.

I know about dimensionality reduction techniques, but I need a really simple and easy to use tool (in matlab, python or a prebuilt .exe).

Also I wonder is representation in 2D going to be "meaningful"? (For example how two classes intersect or can be separable).

You could give tSNE a try. It is pretty straightforward to use. It works with Octave, in addition to Matlab and Python. Take a look at the guide to get a first plot within a minute.
