Early esophageal cancer detection using deep learning techniques (review article)

المجلة: Journal of Physics: Conference Series

سنة النشر: 2021

تاريخ النشر: 2021-09-16

Esophageal cancer is one of the deadliest diseases for humans, since it is discovered in very advanced stages. As result, pathologists are increasingly relying in image recognition and artificial intelligence tools to aid in the early identification and evaluation of this lesion. We examined a number of papers that dealt with this issue during the time span in order to shed light on the studies that were performed in this area (2017 and 2020). We have looked at experiments that used Convolutional Neural Network (CNN) technologies in the study of endoscopic images to help with early detection or diagnosis of esophageal cancer and its various forms. More research on esophageal malignant growth is required, as well as improving the disease's indicative existence and employing more proven techniques for feature selection/extraction of endoscopic images. The aim of this review is to highlight the research conducted on endoscopic images of the esophagus using deep learning algorithms, including CNN, Support Vector Machine (SVM), Random Forests (RF) and other techniques that were used to design the Computer-Aided Detection (CAD) system. In this review we covered some but not all articles that was of great contact with our master's thesis research in this regard.

Many researchers across scientific disciplines have presented countless studies in favor of COVID-19 vaccination, but misinformation on social media could hinder vaccination efforts and increase vaccine hesitancy. Nevertheless, studying people's perceptions on social media to understand their sentiment presents a powerful medium for researchers to identify the causes of vaccine hesitancy and therefore develop appropriate public health messages and interventions. To the best of the authors' knowledge, previous studies have presented vaccine hesitancy in specific cases or within one scientific discipline (i.e., social, medical, and technological). No previous study has presented findings via sentiment analysis for multiple scientific disciplines as follows: (1) social, (2) medical, public health, and (3) technology sciences. Therefore, this research aimed to review and analyze articles related to different vaccine hesitancy cases in the last 11 years and understand the application of sentiment analysis on the most important literature findings. Articles were systematically searched in Web of Science, Scopus, PubMed, IEEEXplore, ScienceDirect, and Ovid from January 1, 2010, to July 2021. A total of 30 articles were selected on the basis of inclusion and exclusion criteria. These articles were formed into a taxonomy of literature, along with challenges, motivations, and recommendations for social, medical, and public health and technology sciences. Significant patterns were identified, and opportunities were promoted towards the understanding of this phenomenon.

The methodology includes parameter initialization, random phase shift generation for IRS elements, modeling of network layouts with random sensor and access point positions, distance computation, gain calculation, SNR determination, and data visualization. The research discusses challenges associated with IRS technology, including design complexity, channel estimation, real-time adaptability, synchronization, hardware constraints, interference management, security, scalability, regulatory compliance, environmental factors, and hardware imperfections. The core of the proposed methodology lies in the fine-grained control of phase shifts by IRS elements, offering valuable insights into signal quality improvement. The code's adaptability is demonstrated through default parameter settings, random phase shift generation, and modelling of sensor, access point, and IRS locations in a confined space. SNR calculations for various sensor-access point pairs and data visualization provide a clear representation of network performance.

This study delves into the investigation of the efficacy of Convolutional Neural Networks (CNNs) in identifying malaria through the examination of cell images. The dataset employed encompasses a total of 27,558 images, harvested from the renowned Malaria Cell Images Dataset on Kaggle, encompassing cells of diverse nature. The architectonics of the CNN model is meticulously devised, comprising of six blocks and three interconnected blocks, thereby rendering an efficient extraction of features and subsequent classification of the cells. Creative paraphrasing: Various strategies such as dropout, batch normalization, and global average pooling are artfully utilized to refine and fortify the model, ensuring its robustness and adaptability. In order to confront the challenge of diminishing gradient and facilitate the attainment of convergence, the activation function known as Rectified Linear Unit (ReLU) is ingeniously employed. Assessing the efficacy of the model via a perplexity grid produces outcomes. Exhibiting a precision rate of 99.59%, a specificity measure of 99.69%, an Sensitivity of 99.40%, F1 Measurement of 99.44%, and a Precision of 99.48, it showcases its capacity to effectively distinguish betwixt malaria-afflicted cells and unafflicted cells. The focal point of this research highlights the substantial potential of CNNs in facilitating the automated identification of malaria using image analysis. By harnessing their unique architecture and regularization techniques, CNNs have the capability to enhance the results and potentially bring about better outcomes in areas with prevalent cases of malaria.

Background and Objectives:- Esophageal malignant growth is probably the deadliest kind of disease in people. It positions seventh as far as disease and 6th as far as passings worldwide, as indicated by the insights of the World Health Organization for the year 2020. That is why we aim to develop a computer system that works on the early detection of esophageal cancer using modern image processing techniques and algorithms. To reduce the death rate by helping specialized doctors to detect it in its early condition. In our research, we relied on the use the Fuzzy C-Means (FCM) algorithm at the stage of clustering and segmentation. In addition, it could use the Convolutional Neural Network (CNN) algorithm in the detection stage. After applying the proposed system to 100 color esophagogastroduodenoscopy images that we downloaded from the Kaggle website, we obtained an accuracy of up to 95%. Note that we did not find researchers who used this data set in their systems to the best of our knowledge. It has been noticed that using the FCM algorithm with the CNN algorithm added a good character in detecting esophageal cancer, although the FCM algorithm needs a lot of development to get the results.

Detecting breast cancer promptly holds utmost importance in ensuring effective treatment, as it is a matter of great concern in the global health context. The primary objective of this research endeavor is to enhance the process of breast cancer identification through the utilization of a Convolutional Neural Network (CNN). The purpose of this study is to mitigate potential errors in human interpretation of mammograms by comparing this approach to conventional machine-learning techniques. In our present investigation on breast imaging, we have leveraged the well-established mammographic dataset, CBIS-DDSM. This dataset effectively categorizes the images into three distinct classes: normal, benign, or malignant. This compilation encompasses a grand sum of 10,239 images. A myriad of approaches were employed to arrange the content, including the manipulation of the image dimensions to a size of 256x256 pixels. A CNN architecture that was specifically crafted was educated through the fusion of backpropagation and angle plunge techniques. Numerous measures, such as sensitivity, specificity, F1 score, and accuracy, were deftly utilized to thoroughly assess the model's effectiveness. It is truly awe-inspiring to witness the outstanding exhibition of performance showcased by the CNN model, as evidenced by the extraordinary values attained for sensitivity, specificity, F1 score, total precision, and accuracy, all of which are undeniably remarkable. These evaluations undeniably serve as irrefutable evidence that the model possesses exceptional diagnostic capabilities, surpassing even the most advanced techniques currently in use. In truth …
