This is the code for Low-rank geometric mean metric learning.

Pre-requisites: MATLAB (the following gode for tested with MATLAB R2017a, but it should also run on previous versions without much issue).

Instructions: 0. Run the following in MATLAB.

  1. run_me_first: This files adds appropriate folders/files to path. You should start with it.
  2. runner: Runs the LR-GMML code for a dataset for various values of t, for a specific number of times. It gives back min, max and average of test errors and writes it to file. For the metrics shows in paper, we are taking average of 5 runs.

One should be able to reproduce our results by running the above two steps.

Note: Step number 2 may take some time because we are running the algorithm lot's of times. One can limit the values of "t" and numRandomIterations to limit the number of runs.
