[WIP] Add SSRBM CIFAR-10 Test

[ShikharJ]

Relevant: #1207

For the test we can just hardcode the dataset, no need to use the cli methods.

@ShikharJ @zoq I'll work on this issue 👍

@ShikharJ @zoq I am able to import data into arma::mat. According to the CIFAR-10 documentation,
The binary version contains the files formatted as follows:
<1 x label><3072 x pixel>
The dimension of the armadillo matrix after .load() is: 3841250 x 1
I tried this code:
std::cout<<testData(0, 0)<<std::endl;
and also this,
std::cout<<testData(3073, 0)<<std::endl;
but both are not giving me the class number.
I also tried reshaping and extracting the first row thinking that it would be the set of labels:

trainData = arma::reshape(trainData, 3073, 1250);
trainLabels = trainData.col(0);

but even that is not giving me the class labels. What mistake am I making?

Sorry for the slow response, which format (binary,matlab,python,csv) of the dataset do you use?

[heisenbuug]

I was actually thinking of taking this as my GSoC project. Can you tell me what all work needs to be done so I can create an effective proposal.

@zoq I am using binary format for the dataset.

Hey, I was thinking to complete the PR. While building the PR, cmake produces error: make[3]: *** No rule to make target '../src/mlpack/core/arma_extend/fn_ccov.hpp', needed by 'src/mlpack/cotire/mlpack_CXX_prefix.hxx.gch'. Stop. This filename doesn't exist in master branch at least, was this file renamed or something?

[rcurtin]

Clearing your build directory and reconfiguring CMake from scratch should fix that, or alternately, maybe fn_ccov.hpp is still referenced on this branch somewhere in some CMakeLists.txt file?

[khizirsiddiqui]

@rcurtin I couldn't find fn_ccov.hpp anywhere in tests/CMakeLists.txt or any other cmake file. Isn't this strange?
Honestly, I do not know much about writing CMake files, so I will give it a try after reading through some relevant tutorials. 👍

[rcurtin]

It may be leftover from a previous build; we removed fn_ccov.hpp some time ago. Did you try clearing the build directory? It's also possible that fn_ccov.hpp is referenced somewhere in the codebase on this branch, so be sure to search through every file; for instance with grep or something.

[rcurtin]

This code touches the ANN code, and there was recently a big refactoring of the ANN code in #2259, so be sure to merge the master branch into your branch here to make sure that nothing will fail if this PR is merged. 👍 (I'm pasting this message into all possibly relevant PRs.)
