2012 Lecture Notes in Computer Science  
By combining decoding hypotheses from both directions, we achieve a significant increase in recognition accuracy for the off-line writer independent handwriting recognition task.  ...  A common approach is to represent a text line as a sequence. It is processed in one direction and the language information via n-grams is directly included in the decoding.  ...  The authors thank Alex Graves for kindly providing us with the BLSTM Neural Network source code and Oriol Ramos Terrades for insightful discussions.  ...
