Missing LaTeX commands: `\land` and `\lor` #6

DeTeXt doesn't know about \land:

I have a guess as the source of the mistake: \land and \wedge are synonymous. Maybe DeTeXt does not correctly import and handle synonymous commands?

The list of LaTeX commands to import can be found here: https://github.com/venkatasg/DeTeXt-Supplementary/blob/main/class_names.txt -- as I suspected, \wedge is present but \land and \lor are missing.

This is the definitive list from what I can tell : https://ctan.org/pkg/comprehensive?lang=en

Yeah I only include commands that are in my training set of images, which are from the Detexify public repository. If I don't have data for a particular command, I don't include those commands since the neural network won't recognize them anyway.

@venkatasg Ok, thanks. What Detexify repository has the training images? Perhaps I can contribute over there.

It isn't actively maintained anymore unfortunately, but here it is: https://github.com/kirel/detexify-data

Beyond training dataset.
