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.

Credit Card Auto-Fill

TL;DR: In this paper, the credit card recognition process may include: obtaining a first representation of a first image, wherein the first representation comprises a first plurality of pixels; identifying a first credit card region within the first image; extracting a plurality of sub-regions from within the identified first card region; generating a predicted character sequence for the first, second, and third subregions; and validating the predicted character sequences for at least the first and the third sub regions using various credit card-related heuristics, e.g., expected character sequence length, expected sequence format
