Cliniciansâ Guide to Artificial Intelligence in Colon Capsule EndoscopyâTechnology Made Simple
Artificial intelligence (AI) applications have become widely popular across the healthcare ecosystem. Colon capsule endoscopy (CCE) was adopted in the NHS England pilot project following the recent COVID pandemicâs impact. It demonstrated its capability to relieve the national backlog in endoscopy. As a result, AI-assisted colon capsule video analysis has become gastroenterologyâs most active research area. However, with rapid AI advances, mastering these complex machine learning concepts remains challenging for healthcare professionals. This forms a barrier for clinicians to take on this new technology and embrace the new era of big data. This paper aims to bridge the knowledge gap between the current CCE system and the future, fully integrated AI system. The primary focus is on simplifying the technical terms and concepts in machine learning. This will hopefully address the general âfear of the unknown in AIâ by helping healthcare professionals understand the basic principle of machine learning in capsule endoscopy and apply this knowledge in their future interactions and adaptation to AI technology. It also summarises the evidence of AI in CCE and its impact on diagnostic pathways. Finally, it discusses the unintended consequences of using AI, ethical challenges, potential flaws, and bias within clinical settings
Advancements in eHealth Data Analytics through Natural Language Processing and Deep Learning
The healthcare environment is commonly referred to as "information-rich" but
also "knowledge poor". Healthcare systems collect huge amounts of data from
various sources: lab reports, medical letters, logs of medical tools or
programs, medical prescriptions, etc. These massive sets of data can provide
great knowledge and information that can improve the medical services, and
overall the healthcare domain, such as disease prediction by analyzing the
patient's symptoms or disease prevention, by facilitating the discovery of
behavioral factors for diseases. Unfortunately, only a relatively small volume
of the textual eHealth data is processed and interpreted, an important factor
being the difficulty in efficiently performing Big Data operations. In the
medical field, detecting domain-specific multi-word terms is a crucial task as
they can define an entire concept with a few words. A term can be defined as a
linguistic structure or a concept, and it is composed of one or more words with
a specific meaning to a domain. All the terms of a domain create its
terminology. This chapter offers a critical study of the current, most
performant solutions for analyzing unstructured (image and textual) eHealth
data. This study also provides a comparison of the current Natural Language
Processing and Deep Learning techniques in the eHealth context. Finally, we
examine and discuss some of the current issues, and we define a set of research
directions in this area
Artificial Intelligence in Invoice Recognition: a Systematic Literature Review
In the era marked by a flourishing economy and rapid advancements in information
technology, the proliferation of invoice data has accentuated the urgent need for
automated invoice recognition. Traditional manual methods, long relied upon for this
task, have proven to be inefficient, error-prone, and incapable of coping with the rising
volume of invoices. This research endeavours to addresses the imperative of automating
invoice recognition by exploring, assessing, and advancing cutting-edge algorithms,
techniques, and methods within the domain of Artificial Intelligence (AI).
This research conducts a comprehensive Systematic Literature Review (SLR) to
investigate Computer Vision (CV) approaches, encompassing image preprocessing,
Layout Analysis (LA), Optical Character Recognition (OCR), and Information Extraction
(IE). The objective is to provide valuable insights into these fundamental components of
invoice recognition, emphasizing their significance in achieving accuracy and efficiency.
This exploration aims to contribute to the development of more effective automated
systems for extracting information from invoices, addressing the challenges posed by
diverse formats and content.
The results indicate that in LA, the combination of Mask Region-based Convolutional
Neural Networks (M-RCNN) and Feature Pyramid Network (FPN) achieves goods
results. In OCR, algorithms like Convolutional Recurrent Neural Network (CRNN), You
Only Look Once version 4 (YOLOv4) and models inspired by M-RCNN and Faster
Region-based Convolutional Neural Network (F-RCNN) with ResNetXt-101 as the
backbone demonstrate remarkable performance. When it comes to IE, algorithms inspired
by F-RCNN and Region Proposal Network (RPN), Grid Convolutional Neural Network
(G-CNN) and Layer Graph Convolutional Networks (LGCN), and Gated Graph
Convolutional Network (GatedGCN) consistently deliver the best results
