+Collects and builds the largest dataset to date from online sources, creating a robust and generalizable dataset. This dataset includes approximately **3.4 million image-text pairs**, including both handwritten mathematical expressions (200,330 examples) and printed mathematical expressions (3,237,250 examples). Due to the large dataset and the fact that the same mathematical formula can be represented in different LaTeX string formats in an image, it is easy to cause polymorphic ambiguity. To address this issue, we use the normalization method with KaTeX parser.
+
+- **Printed mathematical expressions:** We collect from Im2latex-100k dataset [1], I2L-140K Normalized dataset and Im2latex-90k Normalized dataset [2], Im2latex-170k dataset [3], Im2latex-230k dataset [4], latexformulas dataset [5] and Im2latex dataset [6].
+- **Handwritten mathematical expressions:** We collected data from the Competition on Recognition of Online Handwritten Mathematical Expressions (CROHME) dataset [7, 8, 9], Aida Calculus Math Handwriting Recognition
+Dataset [10] and Handwritten Mathematical Expression Convert LaTeX [11].
