Considering the prevalent use of medical information systems and medical databases, ANN have found useful applications in biomedical areas in diagnosis and disease monitoring . Zhang et al (2018) report that in comparison to linear models, ANN are not only difficult to interpret but the identification of predictors (input features) important for the model also seem to be a challenge . Although a 70:30 ratio can typically be used for training/testing size , various statistical sampling techniques ranging from simple (e.g. The idea of ANNs is based on the belief that working of human brain by making the right connections, can be imitated using silicon and wires as living neurons and dendrites. The Journal of Artificial Neural Networks is an academic journal – hosted by OMICS International – a pioneer in open access publishing–and is listed among the top 10 journals in artificial neural networks. Each year research scientists have noticed … Topics categorized under ‘Organizational Behaviour’ include: behaviour and perspectives, crisis or risk management, clinical and non-clinical decision-making, and resource management (S2 Appendix). To our knowledge, this is the first attempt to comprehensively describe the use of ANN in health care, from the time of its origins to current day use, on all levels of organizational decision-making. Like human neural networks, their processing power arises from multiple units. In most cases, it would involve using blood tests, taking tests of the patient’s vitals, and more to identify features that have proven to be good predictors of patient health. Han and colleagues (2012) write that where classification predicts categorical labels, regression is used to predict missing or unavailable numerical data values (rather than discrete class labels). Main topics or area of interest based on the article’s overall purpose included Organizational Behaviour (18%), Cardiovascular (14%), Infectious Disease and Telemedicine (7%) (Table 2). ‘Flow’ is a key concept in a Lean System and ‘information flow’ is an essential improvement target to the successful operation of a health care system using a Lean approach . Title: Applications of Artificial Neural Networks in Medical Science VOLUME: 2 ISSUE: 3 Author(s):Jigneshkumar L. Patel and Ramesh K. Goyal Affiliation:19, Devchhaya Society, Nr.Sattadhar Society, Sola Road, Ghatlodia, Ahmedabad - 380061, Gujarat,India. In consultation with a librarian, a comprehensive search syntax was built on the concepts of ‘artificial neural networks’ applied in ‘health care organizational decision-making’ and tailored for each database for optimum results. These units are arranged in a series of layers that together constitute the whole Artificial Neural Networks in a system. With the digitization of health care , hospitals are increasingly able to collect large amounts of data managed across large information systems . Applications of ANN to diagnosis are well-known; however, ANN are increasingly used to inform health care management decisions. (A) Number of articles by publication year. Institute of Health Policy, Management and Evaluation, University of Toronto, Toronto, Canada, Roles We found ANN to be mainly used for classification, prediction and clinical diagnosis in areas of cardiovascular, telemedicine and organizational behaviour. As suggested by the literature, the most commonly used taxonomy of ANN found was the feed-forward neural network. The authors describe regression analysis as a statistical methodology often used for numeric prediction and encompasses identification of distribution trends based on available data. automated electrocardiographic (ECG) interpretation used to diagnose myocardial infarction ), and drug development. Although the backpropagation learning rule enabled the use of neural networks in many hard medical diagnostic tasks, they have been typically used as black box classifiers lacking the transparency of generating knowledge as well as the ability to explain decision-making . The error in computed and desired outputs can be used to improve model performance. https://doi.org/10.1371/journal.pone.0212356.g002.  A recent survey of AI applications in health care reported uses in major disease areas such as cancer or cardiology and artificial neural networks (ANN) as a common machine learning technique . ANNs (Artificial Neural Networks) are just one of the many models being introduced into the field of healthcare by innovations like AI and big data. How to Model, Train and validate an AI Healthcare Problem –> 3 lectures • 21min. Its application is particularly valuable under one or more of several conditions: when sample data show complex interaction effects or do not meet parametric assumptions, when the relationship between independent and dependent variables is not strong, when there is a large unexplained variance in information, or in situations where the theoretical basis of prediction is poorly understood . With its ability to process large datasets, machine learning technology is well-suited for analysing medical data and providing effective algorithms . These abstractions can therefore capture complex relationships that might not be initially obvious – leading to better prediction for public health. Artificial neural networks for prediction have established themselves as a powerful tool in various applications. selection of network topology, initial weights, choice of control parameters) . In an effort toward moving to value-based care, decision-makers are reported to be strategically shifting the focus to understanding and better alignment of financial incentives for health care providers in order to bear financial risk; population health management including analyses of trends in health, quality and cost; and adoption of innovative delivery models for improved processes and coordination of care. Traditional decision-making processes based on stable and predictable systems are no longer relevant, due to the complex and emergent nature of contemporary health care delivery systems . ANN are similar to statistical techniques including generalized linear models, nonparametric regression and discriminant analysis, or cluster analysis . ANN’s application to facilitate more micro- and meso-level decision-making compared to macro-level may be explained by the type and volume of data required and available to build an effective model. Before 2006, the main successes of ANNs were found in areas like speech processing and image processing. Though they may seem like a futuristic concept, ANNs have been used in healthcare for several decades. These technologies are considered very important. https://doi.org/10.1371/journal.pone.0212356.t001. A review by Agatonovic-Kustrin & Beresford (2000) describes neural computation to be powered from the connection of its neurons and that each neuron has a weighted input, transfer function and a single output. Identified articles were de-duplicated and imported to EndNote as a reference manager and to Covidence, a web-based platform, for screening. Limitations centered around the use of small data sets [42, 53, 66–72], limiting data set to continuous variables , inability to examine causal relationships  or have the network explain weights applied, appropriateness of decision-making [71, 73, 74], difficulty in implementation or understanding of the output . Variables selected for data collection were based on bodies of work with similar inquiry and well aligned with the methods of a scoping review. With its ability to discover hidden knowledge and values, scholars have suggested using ANN to improve care performance and facilitate the adoption of ‘Lean thinking’ or value-based decision making in health care . Now let’s understand how AI is impacting healthcare.. departmental or organizational level) where patient preference may be important but not essential; and on a wider (macro) level by large groups or public organizations related to allocation or utilization of resources where decisions are based on public interest and reflective of society as a whole . Although ANN do not require knowledge of data source, they require large training sets due to the numerous estimated weights involved in computation . These inputs create electric impulses, which quickly t… (B) Number of articles by country. industry and trade databases) are typically used to supplement internal data sources. Although lacking the ability to explain decision-making, ANN-based decision-support tools enable health care organizational decision-makers to respond to complex and emergent environments using incoming and evolving data. Information related to study characteristics, aim, methodology (application, taxonomy, accuracy) and context including organizational level of analysis (micro-, meso- and macro-) was collected and entered into Microsoft Excel for categorization and descriptive analysis. We screened 3,397 articles from six databases with coverage of Health Administration, Computer Science and Business Administration.

I tried to explain the Artificial Neural Network and Implementation of Artificial Neural Network in Python From Scratch in a simple and easy to understand way. Neural networks -- also called artificial neural networks -- are a variety of deep learning technologies. By constructing multiple layers of neurons, each of which receives part of the input variables, and then passes on its results to the next layers, the network can learn very complex functions. Agents (e.g. especially in the healthcare industry where adoption remains in its infancy With the rapid uptake of artificial intelligence to make increasingly complex decisions across different industries, there are a multitude of solutions capable of addressing these health care management challenges; however, there is a paucity of guidance on selecting appropriate methods tailored to the health care industry. This is potentially why ANNs are more commonly used during situations wherein we have a lot of data to ensure that the observed data doesn’t contain too many “flukes”. https://doi.org/10.1371/journal.pone.0212356.g001. Artificial Neural Networks are used in Oncology to train algorithms that can identify cancerous tissue at the microscopic level at the same accuracy as trained physicians. There are two Artificial Neural Network topologies − FeedForward and Feedback. https://doi.org/10.1371/journal.pone.0212356, Editor: Olalekan Uthman, The University of Warwick, UNITED KINGDOM, Received: October 4, 2018; Accepted: January 31, 2019; Published: February 19, 2019. Artificial Neural Networks (ANNs) are one out of many models in machine learning which can be used for the purpose of going from raw data to making useful decisions using that data. The ANN-based models were utilized to estimate the confirmed cases of COVID-19 in China, Japan, Singapore, Iran, Italy, South Africa and United States of America. Modeling the human neuron in computers yielded the basic design of early ANNs. Project administration, The selection of the three disciplines reflects the core concepts embedded in our research question: ‘what are the different applications of ANN (Computer Science) in health care organizational decision-making (Health Administration and Business Management)?’.
