Connectionist temporal classification: labelling unsegmented sequence data with recurrent neural networks

TLDR
This paper presents a novel method for training RNNs to label unsegmented sequences directly, thereby solving both problems of sequence learning and post-processing.
Abstract
Many real-world sequence learning tasks require the prediction of sequences of labels from noisy, unsegmented input data. In speech recognition, for example, an acoustic signal is transcribed into words or sub-word units. Recurrent neural networks (RNNs) are powerful sequence learners that would seem well suited to such tasks. However, because they require pre-segmented training data, and post-processing to transform their outputs into label sequences, their applicability has so far been limited. This paper presents a novel method for training RNNs to label unsegmented sequences directly, thereby solving both problems. An experiment on the TIMIT speech corpus demonstrates its advantages over both a baseline HMM and a hybrid HMM-RNN.

Writer-aware CNN for parsimonious HMM-based offline handwritten Chinese text recognition

TL;DR: Wang et al. as mentioned in this paper proposed a writer-aware CNN based on parsimonious HMM (WCNN-PHMM), which integrates each convolutional layer with one adaptive layer fed by a writer dependent vector to extract the irrelevant variability in writer information to improve recognition performance.
