The issue might be due to some missing files in MATLAB search path.
Try restoring MATLAB's default search path by executing the following commands in MATLAB command window :
>restoredefaultpath
>rehash toolboxcache
Hope this works.

No... It does not work. I have tried to re-install the machine learning app but it still fails while launching.
