As a classification task, the evaluation of the submissions will be based on the percentage of correctly classified samples.  

To make a submission, you need to write out your predicted labels for each on the data point in the test_image matrix as a CSV file, in the following format:   
Id,Category  
0,2  
1,3  
2,9  
Note that the first row is the header. The first column is the index of the data point, which should be 0-4999 since we have 5000 test samples. The second column is the predicted label.
