Lowercase letters.

Hey,

Is there a way to extract lowercase letters alone? I noticed that they are merged with its uppercase counterparts. I'm working with "letters" dataset.

Thanks in advance.

I found the answer to my question. It turns out that "letters" dataset has got merged lowercase and uppercase classes, so that letters "a" and "A" is the same thing at this point. "balanced" dataset, however merges only some of the letter classes, specifically the ones that are not different from its uppercase counterparts. This is depicted on this picture:

Where the upper arrows mean that particular lowercase letter class was merged with its uppercase counterpart.

Cheers!
