A Developmental Neuro-Robotics Approach for Boosting the Recognition of Handwritten Digits
Developmental psychology and neuroimaging
research identified a close link between numbers and fingers,
which can boost the initial number knowledge in children. Recent
evidence shows that a simulation of the children's embodied
strategies can improve the machine intelligence too. This article
explores the application of embodied strategies to convolutional
neural network models in the context of developmental neurorobotics, where the training information is likely to be gradually
acquired while operating rather than being abundant and fully
available as the classical machine learning scenarios. The
experimental analyses show that the proprioceptive information
from the robot fingers can improve network accuracy in the
recognition of handwritten Arabic digits when training examples
and epochs are few. This result is comparable to brain imaging
and longitudinal studies with young children. In conclusion, these
findings also support the relevance of the embodiment in the case
of artificial agents’ training and show a possible way for the
humanization of the learning process, where the robotic body can
express the internal processes of artificial intelligence making it
more understandable for humans
Huruf: An Application for Arabic Handwritten Character Recognition Using Deep Learning
Handwriting Recognition has been a field of great interest in the Artificial
Intelligence domain. Due to its broad use cases in real life, research has been
conducted widely on it. Prominent work has been done in this field focusing
mainly on Latin characters. However, the domain of Arabic handwritten character
recognition is still relatively unexplored. The inherent cursive nature of the
Arabic characters and variations in writing styles across individuals makes the
task even more challenging. We identified some probable reasons behind this and
proposed a lightweight Convolutional Neural Network-based architecture for
recognizing Arabic characters and digits. The proposed pipeline consists of a
total of 18 layers containing four layers each for convolution, pooling, batch
normalization, dropout, and finally one Global average pooling and a Dense
layer. Furthermore, we thoroughly investigated the different choices of
hyperparameters such as the choice of the optimizer, kernel initializer,
activation function, etc. Evaluating the proposed architecture on the publicly
available 'Arabic Handwritten Character Dataset (AHCD)' and 'Modified Arabic
handwritten digits Database (MadBase)' datasets, the proposed model
respectively achieved an accuracy of 96.93% and 99.35% which is comparable to
the state-of-the-art and makes it a suitable solution for real-life end-level
applications.Comment: Accepted in 25th ICCIT (6 pages, 4 tables, 4 figures
NeuroWrite: Predictive Handwritten Digit Classification using Deep Neural Networks
The rapid evolution of deep neural networks has revolutionized the field of
machine learning, enabling remarkable advancements in various domains. In this
article, we introduce NeuroWrite, a unique method for predicting the
categorization of handwritten digits using deep neural networks. Our model
exhibits outstanding accuracy in identifying and categorising handwritten
digits by utilising the strength of convolutional neural networks (CNNs) and
recurrent neural networks (RNNs).In this article, we give a thorough
examination of the data preparation methods, network design, and training
methods used in NeuroWrite. By implementing state-of-the-art techniques, we
showcase how NeuroWrite can achieve high classification accuracy and robust
generalization on handwritten digit datasets, such as MNIST. Furthermore, we
explore the model's potential for real-world applications, including digit
recognition in digitized documents, signature verification, and automated
postal code recognition. NeuroWrite is a useful tool for computer vision and
pattern recognition because of its performance and adaptability.The
architecture, training procedure, and evaluation metrics of NeuroWrite are
covered in detail in this study, illustrating how it can improve a number of
applications that call for handwritten digit classification. The outcomes show
that NeuroWrite is a promising method for raising the bar for deep neural
network-based handwritten digit recognition.Comment: 6 pages, 10 figure
Does color modalities affect handwriting recognition? An empirical study on Persian handwritings using convolutional neural networks
Most of the methods on handwritten recognition in the literature are focused
and evaluated on Black and White (BW) image databases. In this paper we try to
answer a fundamental question in document recognition. Using Convolutional
Neural Networks (CNNs), as eye simulator, we investigate to see whether color
modalities of handwritten digits and words affect their recognition accuracy or
speed? To the best of our knowledge, so far this question has not been answered
due to the lack of handwritten databases that have all three color modalities
of handwritings. To answer this question, we selected 13,330 isolated digits
and 62,500 words from a novel Persian handwritten database, which have three
different color modalities and are unique in term of size and variety. Our
selected datasets are divided into training, validation, and testing sets.
Afterwards, similar conventional CNN models are trained with the training
samples. While the experimental results on the testing set show that CNN on the
BW digit and word images has a higher performance compared to the other two
color modalities, in general there are no significant differences for network
accuracy in different color modalities. Also, comparisons of training times in
three color modalities show that recognition of handwritten digits and words in
BW images using CNN is much more efficient
