Handwriting recognition and automatic scoring for descriptive answers in Japanese language tests
Hung Tuan Nguyen, Cuong Tuan Nguyen, Haruki Oka +2
This paper presents an experiment of automatically scoring handwritten descriptive answers in the trial tests for the new Japanese university entrance examination, which were made…
A Transformer-based Math Language Model for Handwritten Math Expression Recognition
Huy Quang Ung, Cuong Tuan Nguyen, Hung Tuan Nguyen +2
Handwritten mathematical expressions (HMEs) contain ambiguities in their interpretations, even for humans sometimes. Several math symbols are very similar in the writing style, suc…
Recurrent neural network transducer for Japanese and Chinese offline handwritten text recognition
Trung Tan Ngo, Hung Tuan Nguyen, Nam Tuan Ly +1
In this paper, we propose an RNN-Transducer model for recognizing Japanese and Chinese offline handwritten text line images. As far as we know, it is the first approach that adopts…
GSSF: A Generative Sequence Similarity Function based on a Seq2Seq model for clustering online handwritten mathematical answers
Huy Quang Ung, Cuong Tuan Nguyen, Hung Tuan Nguyen +1
Toward a computer-assisted marking for descriptive math questions,this paper presents clustering of online handwritten mathematical expressions (OnHMEs) to help human markers to ma…
Global Context for improving recognition of Online Handwritten Mathematical Expressions
Cuong Tuan Nguyen, Thanh-Nghia Truong, Hung Tuan Nguyen +1
This paper presents a temporal classification method for all three subtasks of symbol segmentation, symbol recognition and relation classification in online handwritten mathematica…
Learning symbol relation tree for online mathematical expression recognition
Thanh-Nghia Truong, Hung Tuan Nguyen, Cuong Tuan Nguyen +1
This paper proposes a method for recognizing online handwritten mathematical expressions (OnHME) by building a symbol relation tree (SRT) directly from a sequence of strokes. A bid…
Text-independent writer identification using convolutional neural network
Hung Tuan Nguyen, Cuong Tuan Nguyen, Takeya Ino +2
The text-independent approach to writer identification does not require the writer to write some predetermined text. Previous research on text-independent writer identification has…
Online trajectory recovery from offline handwritten Japanese kanji characters
Hung Tuan Nguyen, Tsubasa Nakamura, Cuong Tuan Nguyen +1
In general, it is straightforward to render an offline handwriting image from an online handwriting pattern. However, it is challenging to reconstruct an online handwriting pattern…
End to End Recognition System for Recognizing Offline Unconstrained Vietnamese Handwriting
Anh Duc Le, Hung Tuan Nguyen, Masaki Nakagawa
Inspired by recent successes in neural machine translation and image caption generation, we present an attention based encoder decoder model (AED) to recognize Vietnamese Handwritt…
Pattern Generation Strategies for Improving Recognition of Handwritten Mathematical Expressions
Anh Duc Le, Bipin Indurkhya, Masaki Nakagawa
Recognition of Handwritten Mathematical Expressions (HMEs) is a challenging problem because of the ambiguity and complexity of two-dimensional handwriting. Moreover, the lack of la…
