An attention based image to latex markup decoder

Inspired by recent work in Optical Character Recognition (OCR) and image captioning, an end-to-end system is utilized which implements the recognition of image formulas. An attention based two-way encoder-decoder structure has been proposed to normal image captioning systems, and it achieves good performance on the recognition of image formulas task. This structure together with a new training method is used to achieve a better result on the famous IM2LATEX-100K dataset.
