BCNet: A Novel Network for Blood Cell Classification
The paper was partially supported by: Royal Society International Exchanges Cost Share Award, United Kingdom (RP202G0230); Medical Research Council Confidence in Concept Award, United Kingdom (MC_PC_17171); Hope Foundation for Cancer Research, United Kingdom (RM60G0680); British Heart Foundation Accelerator Award, United Kingdom (AA/18/3/34220); Sino-United Kingdom Industrial Fund, United Kingdom (RP202G0289); Global Challenges Research Fund (GCRF), United Kingdom (P202PF11); Guangxi Key Laboratory of Trusted Software (kx201901).Aims: Most blood diseases, such as chronic anemia, leukemia (commonly known as
blood cancer), and hematopoietic dysfunction, are caused by environmental pollution,
substandard decoration materials, radiation exposure, and long-term use certain drugs.
Thus, it is imperative to classify the blood cell images. Most cell classification is based on
the manual feature, machine learning classifier or the deep convolution network neural
model. However, manual feature extraction is a very tedious process, and the results are
usually unsatisfactory. On the other hand, the deep convolution neural network is usually
composed of massive layers, and each layer has many parameters. Therefore, each deep
convolution neural network needs a lot of time to get the results. Another problem is that
medical data sets are relatively small, which may lead to overfitting problems.
Methods: To address these problems, we propose seven models for the automatic
classification of blood cells: BCARENet, BCR5RENet, BCMV2RENet, BCRRNet,
BCRENet, BCRSNet, and BCNet. The BCNet model is the best model among the
seven proposed models. The backbone model in our method is selected as the
ResNet-18, which is pre-trained on the ImageNet set. To improve the performance of
the proposed model, we replace the last four layers of the trained transferred ResNet-18
model with the three randomized neural networks (RNNs), which are RVFL, ELM, and
SNN. The final outputs of our BCNet are generated by the ensemble of the predictions from
the three randomized neural networks by the majority voting. We use four multiclassification
indexes for the evaluation of our model.
Results: The accuracy, average precision, average F1-score, and average recall are
96.78, 97.07, 96.78, and 96.77%, respectively.
Conclusion: We offer the comparison of our model with state-of-the-art methods. The
results of the proposed BCNet model are much better than other state-of-the-art methods.Royal Society International Exchanges Cost Share Award RP202G0230Medical Research Council Confidence in Concept Award, United Kingdom MC_PC_17171Hope Foundation for Cancer Research, United Kingdom RM60G0680British Heart Foundation Accelerator Award, United Kingdom AA/18/3/34220Sino-United Kingdom Industrial Fund, United Kingdom RP202G0289Global Challenges Research Fund (GCRF), United Kingdom P202PF11Guangxi Key Laboratory of Trusted Software kx20190
Automatic Diagnosis of Schizophrenia and Attention Deficit Hyperactivity Disorder in rs-fMRI Modality using Convolutional Autoencoder Model and Interval Type-2 Fuzzy Regression
Nowadays, many people worldwide suffer from brain disorders, and their health is in danger. So far, numerous methods have been proposed for the diagnosis of Schizophrenia (SZ) and attention deficit hyperactivity disorder (ADHD), among which functional magnetic resonance imaging (fMRI) modalities are known as a popular method among physicians. This paper presents an SZ and ADHD intelligent detection method of resting-state fMRI (rs-fMRI) modality using a new deep learning method. The University of California Los Angeles dataset, which contains the rs-fMRI modalities of SZ and ADHD patients, has been used for experiments. The FMRIB software library toolbox first performed preprocessing on rs-fMRI data. Then, a convolutional Autoencoder model with the proposed number of layers is used to extract features from rs-fMRI data. In the classification step, a new fuzzy method called interval type-2 fuzzy regression (IT2FR) is introduced and then optimized by genetic algorithm, particle swarm optimization, and gray wolf optimization (GWO) techniques. Also, the results of IT2FR methods are compared with multilayer perceptron, k-nearest neighbors, support vector machine, random forest, and decision tree, and adaptive neuro-fuzzy inference system methods. The experiment results show that the IT2FR method with the GWO optimization algorithm has achieved satisfactory results compared to other classifier methods. Finally, the proposed classification technique was able to provide 72.71% accuracy

for early detection of breast cancer. Computer-Aided (CAD) systems have played a crucial role
in facilitating quicker diagnostic procedures, which otherwise could take weeks if only radiologists
were involved. In some of these CAD systems, breast pectoral segmentation is required for breast region
partition from breast pectoral muscle for specific analysis tasks. Therefore, accurate and efficient
breast pectoral muscle segmentation frameworks are in high demand. Here, we proposed a novel
deep learning framework, which we code-named PeMNet, for breast pectoral muscle segmentation
in mammography images. In the proposed PeMNet, we integrated a novel attention module called
the Global Channel Attention Module (GCAM), which can effectively improve the segmentation
performance of Deeplabv3+ using minimal parameter overheads. In GCAM, channel attention maps
(CAMs) are first extracted by concatenating feature maps after paralleled global average pooling and
global maximum pooling operation. CAMs are then refined and scaled up by multi-layer perceptron
(MLP) for elementwise multiplication with CAMs in next feature level. By iteratively repeating
this procedure, the global CAMs (GCAMs) are then formed and multiplied elementwise with final
feature maps to lead to final segmentation. By doing so, CAMs in early stages of a deep convolution
network can be effectively passed on to later stages of the network and therefore leads to better
information usage. The experiments on a merged dataset derived from two datasets, INbreast and
OPTIMAM, showed that PeMNet greatly outperformed state-of-the-art methods by achieving an
IoU of 97.46%, global pixel accuracy of 99.48%, Dice similarity coefficient of 96.30%, and Jaccard of
93.33%, respectively.CSCRoyal Society International Exchanges Cost Share Award, UK RP202G0230Medical Research Council Confidence in Concept Award, UK MC_PC_17171Hope Foundation for Cancer Research, UK RM60G0680Sino-UK Industrial Fund, UK RP202G0289Global Challenges Research Fund (GCRF), UK P202PF11British Heart Foundation Accelerator Award, UK AA/18/3/34220Guangxi Key Laboratory of Trusted Software kx201901FEDER Una manera de hacer Europa RTI2018-098913-B100Junta de AndaluciaEuropean Commission CV20-45250

An overview of artificial intelligence techniques for diagnosis of Schizophrenia based on magnetic resonance imaging modalities: Methods, challenges, and future works
Schizophrenia (SZ) is a mental disorder that typically emerges in late adolescence
or early adulthood. It reduces the life expectancy of patients by 15 years.
Abnormal behavior, perception of emotions, social relationships, and reality
perception are among its most significant symptoms. Past studies have revealed
that SZ affects the temporal and anterior lobes of hippocampus regions of the brain. Also, increased volume of cerebrospinal fluid (CSF) and decreased
volume of white and gray matter can be observed due to this disease. Magnetic
resonance imaging (MRI) is the popular neuroimaging technique used to
explore structural/functional brain abnormalities in SZ disorder, owing to its
high spatial resolution. Various artificial intelligence (AI) techniques have been
employed with advanced image/signal processing methods to accurately diagnose
SZ. This paper presents a comprehensive overview of studies conducted on
the automated diagnosis of SZ using MRI modalities. First, an AI-based computer
aided-diagnosis system (CADS) for SZ diagnosis and its relevant sections
are presented. Then, this section introduces the most important conventional
machine learning (ML) and deep learning (DL) techniques in the diagnosis of
diagnosing SZ. A comprehensive comparison is also made between ML and DL
studies in the discussion section. In the following, the most important challenges
in diagnosing SZ are addressed. Future works in diagnosing SZ using AI
techniques and MRI modalities are recommended in another section. Results,
conclusion, and research findings are also presented at the end.Ministerio de Ciencia e Innovación

past few decades. It is potentially one of the next steps in revolutionizing human interaction with food. The
modern advent of big data and the development of data-oriented fields like deep learning have provided advancements
in food category recognition. With increasing computational power and ever-larger food datasets,
the approach’s potential has yet to be realized. This survey provides an overview of methods that can be applied
to various food category recognition tasks, including detecting type, ingredients, quality, and quantity. We
survey the core components for constructing a machine learning system for food category recognition, including
datasets, data augmentation, hand-crafted feature extraction, and machine learning algorithms. We place a
particular focus on the field of deep learning, including the utilization of convolutional neural networks, transfer
learning, and semi-supervised learning. We provide an overview of relevant studies to promote further developments
in food category recognition for research and industrial applicationsMRC (MC_PC_17171)Royal Society (RP202G0230)BHF (AA/18/3/34220)Hope Foundation for Cancer Research (RM60G0680)GCRF (P202PF11)Sino-UK Industrial

Applications of Deep Learning Techniques for Automated Multiple Sclerosis Detection Using Magnetic Resonance Imaging: A Review
Multiple Sclerosis (MS) is a type of brain disease which causes visual, sensory, and motor problems for people with a detrimental effect on the functioning of the nervous system. In order to diagnose MS, multiple screening methods have been proposed so far; among them, magnetic resonance imaging (MRI) has received considerable attention among physicians. MRI modalities provide physicians with fundamental information about the structure and function of the brain, which is crucial for the rapid diagnosis of MS lesions. Diagnosing MS using MRI is time-consuming, tedious, and prone to manual errors. Research on the implementation of computer aided diagnosis system (CADS) based on artificial intelligence (AI) to diagnose MS involves conventional machine learning and deep learning (DL) methods. In conventional machine learning, feature extraction, feature selection, and classification steps are carried out by using trial and error; on the contrary, these steps in DL are based on deep layers whose values are automatically learn. In this paper, a complete review of automated MS diagnosis methods performed using DL techniques with MRI neuroimaging modalities is provided. Initially, the steps involved in various CADS proposed using MRI modalities and DL techniques for MS diagnosis are investigated. The important preprocessing techniques employed in various works are analyzed. Most of the published papers on MS diagnosis using MRI modalities and DL are presented. The most significant challenges facing and future direction of automated diagnosis of MS using MRI modalities and DL techniques are also provided

Detection of Epileptic Seizures on EEG Signals Using ANFIS Classifier, Autoencoders and Fuzzy Entropies
Epileptic seizures are one of the most crucial
neurological disorders, and their early diagnosis will help the
clinicians to provide accurate treatment for the patients. The
electroencephalogram (EEG) signals are widely used for epileptic
seizures detection, which provides specialists with substantial
information about the functioning of the brain. In this paper,
a novel diagnostic procedure using fuzzy theory and deep
learning techniques is introduced. The proposed method is
evaluated on the Bonn University dataset with six classification
combinations and also on the Freiburg dataset. The tunable-
Q wavelet transform (TQWT) is employed to decompose the
EEG signals into different sub-bands. In the feature extraction
step, 13 different fuzzy entropies are calculated from different
sub-bands of TQWT, and their computational complexities are
calculated to help researchers choose the best set for various
tasks. In the following, an autoencoder (AE) with six layers
is employed for dimensionality reduction. Finally, the standard
adaptive neuro-fuzzy inference system (ANFIS), and also its
variants with grasshopper optimization algorithm (ANFIS-GOA),
particle swarm optimization (ANFIS-PSO), and breeding swarm
optimization (ANFIS-BS) methods are used for classification.
Using our proposed method, ANFIS-BS method has obtained
an accuracy of 99.7
