Query: Enhancing Handwritten Text Recognition with N-gram sequence
  decomposition and Multitask Learning   Current state-of-the-art approaches in the field of Handwritten Text
Recognition are predominately single task with unigram, character level target
units. In our work, we utilize a Multi-task Learning scheme, training the model
to perform decompositions of the target sequence with target units of different
granularity, from fine to coarse. We consider this method as a way to utilize
n-gram information, implicitly, in the training process, while the final
recognition is performed using only the unigram output. % in order to highlight
the difference of the internal Unigram decoding of such a multi-task approach
highlights the capability of the learned internal representations, imposed by
the different n-grams at the training step. We select n-grams as our target
units and we experiment from unigrams to fourgrams, namely subword level
granularities. These multiple decompositions are learned from the network with
task-specific CTC losses. Concerning network architectures, we propose two
alternatives, namely the Hierarchical and the Block Multi-task. Overall, our
proposed model, even though evaluated only on the unigram task, outperforms its
counterpart single-task by absolute 2.52\% WER and 1.02\% CER, in the greedy
decoding, without any computational overhead during inference, hinting towards
successfully imposing an implicit language model.
