If I am given a pdf image of a mathematical symbolic formula can I translate it into Mathematica syntax using ML?

I tried using Classify, but I can only translate parts of the equation and I don't know how do to group the pieces together. Moreover, I found the training set can not have an equal sign. (I pasted an image because of the images in the training set).

image of the training set

produce this output:

out[201]=ω/k

  • $\begingroup$ Have you tried TextRecognize? $\endgroup$ – Carl Lange May 5 '19 at 18:43
  • $\begingroup$ @Carl Lange Yes, it does not work, I think it's because a math formula is not simply text and so it had a different training. $\endgroup$ – Gluoncito May 5 '19 at 18:55
  • $\begingroup$ It's quite likely that Classify won't work for this, unfortunately. If you have a lot of training data (I suppose it's trivial to generate) you could try to train a neural network to do it. Perhaps Classify will work if you use the right FeatureExtraction - but again, only if you have enough training data. $\endgroup$ – Carl Lange May 5 '19 at 19:00
  • $\begingroup$ I wish I could do it with Mathematica. If the appropriate training model exists in other languages, someone might package it. OCR of math expression $\endgroup$ – Xminer May 6 '19 at 12:36
  • $\begingroup$ @Xminer, thankx for the link. Foxit has an OCR that partialy recognizes the math formulas, but is far from complete. $\endgroup$ – Gluoncito May 6 '19 at 13:45
