////////////////////////////////////////////////////////////////////
CT 5.30.2013
Note: I have only tested this on linux Ubuntu 12.04, with cuda 5.
it should work with previous cuda versions with minor tweaks to the 
build scripts

////////////////////////////////////////////////////////////////////
Compiling:
////////////////////////////////////////////////////////////////////
to make shared CUDA/C++ shared library:
0. install cuda 5
1. cd into cuda_ut folder
2. update variables 'CUDA_PATH' and 'CUDA_SAMPLES_PATH' in Makefile
3. make (this may take 10 mins, make sure that nvcc used is 
		 version 5 and it is on the PATH.)
4. cd modules
5. make mexf="./deep_nn/mexcuConvNNoo.mex ./deep_nn/mexcuConvNNooFF.mex"


////////////////////////////////////////////////////////////////////
Learning:
////////////////////////////////////////////////////////////////////
1. cd to matlab folder
2. download train.csv and test.csv
3. if using tcsh, setenv LD_PRELOAD /usr/lib/x86_64-linux-gnu/libstdc++.so.6
	and setenv LD_LIBRARY_PATH somewhere/face_exp/cuda_ut/lib
	(note that the path for libstdc++.so.6 may vary for different OS)
4. start matlab
5. run load_from_kaggle.m
6. run script_face_exp.m

////////////////////////////////////////////////////////////////////
Prediction:
////////////////////////////////////////////////////////////////////
1. run fe_pred.m
