Rimes is a French handwriting recognition database created by A2iA.
  The database was created by asking individuals to write letters on a given scenario like
  a change of personal information, payment difficulty, damage declaration. The
  dataset has been used in several international research including ICFHR 2008,
  ICDAR-2009, ICDAR-2011 competitions for isolated word level and
  line level recognition tasks.
  
  It contains 11333 training lines and 788 test lines. It does not include
  a validation split but in a recent publication a 10% sampling of the total
  training lines for validation purposes were performed
  (http://www.jpuigcerver.net/pubs/jpuigcerver_icdar2017.pdf).
  We have used a similar train, test and validation split.
