  We introduce MathWriting, the largest online handwritten mathematical
expression dataset to date. It consists of 230k human-written samples and an
additional 400k synthetic ones. MathWriting can also be used for offline HME
recognition and is larger than all existing offline HME datasets like
IM2LATEX-100K. We introduce a benchmark based on MathWriting data in order to
advance research on both online and offline HME recognition.
