I have used the MNIST data set many times to train models for digit recognition based on object character recognition (OCR).

I am now trying to do the same but with a data set of svg paths.. I am trying to find an MNIST equivalent of a digital path / svg based data set.

Here is a sample:

enter image description here

the svg

<path d="m233.5,119.4375c-1,-1 -3.025818,-1.320366 -5,-1c-3.121445,0.506538

I intend to train the model to understand the d= param. MyScript uses this approach rather than OCR, https://developer.myscript.com/. They call their approach iink but is a brand rather than a word I can use to search for material in this space. MyScript works with 2 dimensional data, so not only just the paths but also the relative positions of objects. I am interested in applying this approach to mathematics but for now anything will do.

I managed to fine some stuff

I then found out about 'CROHME' (Competition on Recognition of Online Handwritten Mathematical Expressions) this also uses InkML.
