Health care organizations are leveraging machine-learning techniques, such as artificial neural networks (ANN), to improve delivery of care at a reduced cost. Overview of Artificial neural network in medical diagnosis Other advantages of ANN, relative to traditional predictive modeling techniques, include fast and simple operation due to compact representation of knowledge (e.g., weight and threshold value matrices), the ability to operate with noisy or missing information and generalize to similar unseen data, the ability to learn inductively from training data and process non-linear functionality critical to dealing with real-word data [37]. Data mining pertains to extraction of significant patterns and knowledge discovery and employs inferring algorithms, such as ANN, to pre-processed data to complete data mining tasks such as classification and cluster analysis [79]. Neural networks make use of multiple mathematical processing layers to interpret the given information. As a data-driven agency, CDC has always had highly skilled statisticians and data scientists. Neural network models require less formal statistical training to de- velop: Working artificial neural network models can be developed by newcomers to neurocomputing within a relatively short time frame (i.e., days to weeks), conditional on the availability of an ap- propriate data set and neural network … An Artificial Neural Network (ANN) is an information-processing paradigm that is inspired by the way biological nervous systems, such as the brain, process information. Despite the evident progress in certain areas (e.g. Fig 2 illustrates the overall review process including number of articles excluded at each stage. How to Model, Train and validate an AI Healthcare Problem –> 3 lectures • 21min. (B) Number of articles by country. Appropriate data splitting is a technique commonly used in machine learning in order to minimize poor generalization (also referred to as over-training or over-fitting) of models [34]. Formal analysis, Another advantage reported was improved generalizability, e.g. Artificial Neural Networks in healthcare: A high-level overview ... and the reliability of machine learning is vital since it affects directly or indirectly to patients’ health. 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 [23]. 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. Their purpose is to transform huge amounts of raw data into useful decisions for treatment and care. Types of Artificial Neural Network: 10.4018/978-1-4666-6146-2.ch005: This chapter is a brief explanation about types of neural networks and provides some basic definitions related to feedforward and recurrent neural networks. Despite its many applications and, more recently, its prominence [17], there is a lack of coherence regarding ANN’s applications and potential to inform decision making at different levels in health care organizations. Methodology, Computer technology has been advanced tremendously and the interest has been increased for the potential use of 'Artificial Intelligence (AI)' in medicine and biological research. Factors such as easier integration with hospital workflows, patient-centric treatment plans leading to improved patient outcomes, elimination of unnecessary hospital procedures and reduced treatment costs can influence wider adoption of AI-based solutions in the health care industry [107]. Artificial neural networks are built of simple elements called neurons, which take in a real value, multiply it by a weight, and run it through a non-linear activation function. Each year research scientists have noticed … This study raises the problems of these artificial intelligence blockchains and recognizes blockchain, artificial intelligence, neural networks, healthcare, etc. While neural networks (also called “perceptrons”) have been around since the 1940s, it is only in the last several decades where they have become a major part of artificial intelligence. Global health care expenditure is expected to reach $8.7 trillion by 2020, driven by aging populations growing in size and disease complexity, advancements made in medical treatments, rising labour costs and the market expansion of the health care industry. It presents basic and advanced concepts to help beginners and industry professionals get up to speed on the latest developments in soft computing and healthcare systems. Formal analysis, Conclusion. A white paper published by IBM suggests that with increasing capture and digitization of health care data (e.g. Healthcare. Outside of medicine and health care, Wong et al. Even if published and made available, the connection weight matrices used in ANN for training a data set may be large and difficult to interpret for others to make use of, whereas logistic regression coefficients can be published for any end user to be able to calculate [31]. No, Is the Subject Area "Neural networks" applicable to this article? An example of ANN facilitating Lean thinking adoption in health care contexts is its application to describe ‘information flow’ among cancer patients by modeling the relationship between quality of life evaluations made by patients, pharmacists and nurses [87]. Health care organizations are leveraging machine-learning techniques, such as artificial neural networks (ANN), to improve delivery of care at a reduced cost. Publication dates ranged from 1997 to 2018 with the number of studies fluctuating each year (Fig 3A). In comparing advantages and disadvantages of using ANN to predict medical outcomes, Tu (1996) suggests that logistic regression models can be disseminated to a wider audience, whereas ANN models are less transparent and therefore can be more difficult to communicate and use. Several theoretical implications emerge from our study findings. selection of network topology, initial weights, choice of control parameters) [106]. Originally developed as mathematical theories of the information-processing activity of biological nerve cells, the structural elements used to describe an ANN are conceptually analogous to those used in neuroscience, despite it belonging to a class of statistical procedures [23]. The lack of transparency or interpretability of neural networks continues to be an important problem since health care providers are often unwilling to accept machine recommendations without clarity regarding the underlying rationale [88]. hidden relationships among clinical variables occurring at short and long term events) and irregularity of information used which can reduce model performance if not handled appropriately [88]. Artificial Neural Networks. Policies encouraging transparency and sharing of core datasets across public and private sectors can stimulate higher levels of innovation-oriented competition and research productivity [112]. The complex nature of artificial neural networks required a fundamental understanding for the authors who were otherwise novice to the field. Drug development – Finally, ANNs are used in the development of drugs for various conditions – working by using large amounts of data to come to conclusions about treatment options. industry and trade databases) are typically used to supplement internal data sources. PLOS ONE promises fair, rigorous peer review, Wei Wei, Xiaoning Wu, Jialing Zhou, Yameng Sun, Yuanyuan Kong, Xu Yang, Noninvasive Evaluation of Liver Fibrosis Reverse Using Artificial Neural Network Model for Chronic Hepatitis B Patients, Computational and Mathematical Methods in Medicine, 10.1155/2019/7239780, 2019, (1-8), (2019). 10. Understanding Neural Networks can be very difficult. Roles Formal analysis, single-layer perceptron, multi-layer perceptron, radial basis function networks) or feed-back, or otherwise referred to as recurrent neural networks (e.g. The company recently published its first findings of Ebola treatment drugs last year, and the tools that Atomwise uses can tell the difference between toxic drug candidates and safer options. For instance, in the world of drug discovery, Data Collective and Khosla Ventures are currently backing the company “Atomwise“, which uses the power of machine learning and neural networks to help medical professionals discover safer and more effective medicines fast. Writing – review & editing, Affiliation These units are arranged in a series of layers that together constitute the whole Artificial Neural Networks in a system. The error in computed and desired outputs can be used to improve model performance. According to economy theory, most organizations are risk-aversive [4] and decision-makers in health care can face issues related to culture, technology and risk when making high-risk decisions without the certainty of high-return [4, 5]. As policy-makers adopt strategies towards a value-based, patient-centred model of care delivery, decision-makers are required to consider the readiness of health care organizations for successful implementation and wide-scale adoption of AI or ANN based decision-support tools. By means of this review, we will identify the nature and extent of relevant literature and describe methodologies and context used. Modeling the human neuron in computers yielded the basic design of early ANNs. We found ANN to be mainly used for classification, prediction and clinical diagnosis in areas of cardiovascular, telemedicine and organizational behaviour. Since the introduction of Artificial Intelligence in the 1950s, it has been impacting various domains including marketing, finance, the gaming industry, and even the musical arts. Competing interests: The authors have declared that no competing interests exist. Non-clinical applications have included improvement of health care organizational management [14], prediction of key indicators such as cost or facility utilization [15]. Copyright: © 2019 Shahid et al. The levels pertain to decisions made on the (micro) level of individual patients, or on a (meso) group level (e.g. You have successfully built your first Artificial Neural Network. Okoroh MI(1), Ilozor BD, Gombera P. Author information: (1)Faculty of Arts, Design & Technology, School of Technology, University of Derby, Kedleston Road, Derby, DE22 1GB, UK. Our study found artificial neural networks can be applied across all levels of health care organizational decision-making. Due to the primitive nature of computer technology mid-20th Century, most of the research in machine learning was theoretical or based on construction of special purpose systems [18]. 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. ANNs are the subfield of Artificial Intelligence. Predicting those escalations in advance offers healthcare providers the opportunity to apply preventative measure that might improve patient safety, and quality of care, while lowering medical costs. Applications with lowest estimated potential value include preliminary diagnosis ($5B), automated image ($3B) and cyber-security ($2B) [108]. We found that application of ANN in health care decision-making began in the late 90’s with fluctuating use over the years. During the 90’s, most of the research was largely experimental and the need for use of ANN as a widely-used computer paradigm remained warranted [18]. Is the Subject Area "Artificial neural networks" applicable to this article? Adopters of ANN or researchers new to the field of AI may find the scope and esoteric terminology of neural computing particularly challenging [18]. Where are Artificial Neural Networks and Deep Learning Systems Being Used Today? In ANNs, units correspond to neurons in biological neural networks, inputs to dendrites, connection weights to electrical impulse strengths, and outputs to axons: They work in moments wherein we can collect data, but we don’t understand which pieces of that data are vitally important yet. A subfield of AI, machine learning-as-a-service-market (MLaaS), is expected to reach $5.4 billion by 2022, with the health care sector as a notable key driver [9]. Today, the possibilities for Neural Networks in Healthcare include: Neural networks can be seen in most places where AI has made steps within the healthcare industry. An artificial neural network is created by programming standard, but very powerful, computers to behave like connected brain cells. The basic ANN structure consists of three layers: an input layer, a hidden layer, and an output layer. Dave Pearson | December 23, ... and colleagues explain how they trained an artificial neural network to complete a simple foraging assignment. 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. In an overview of basic concepts, Agatonovic-Kustrin & Beresford (2000) describe ANN gather knowledge by detecting patterns and relationships in data and “learn” through experience.

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”. Prior to 2006, application of neural networks included processing of biomedical signals, for example image and speech processing [89, 90], clinical diagnosis, image analysis and interpretation, and drug development [87]. ANN are similar to statistical techniques including generalized linear models, nonparametric regression and discriminant analysis, or cluster analysis [24]. 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 [22]. Despite successful applications, ANN remain problematic in that they offer us little or no insight into the process(es) by which they learn or the totality of the knowledge embedded in them [38]. One of the most interesting and extensively studied branches of AI is the 'Artificial Neural Networks (ANNs)'. A feed-forward network can be single-layered (e.g. Also referred to as the generalized delta rule, backpropagation refers to how an ANN is trained or ‘learns’ based on data. A neural network is a network of artificial neurons programmed in software. The performance of neural network model is sensitive to training-test split. Methods include naïve Bayesian classification, support vector machines, and k-nearest-neighbour classification [32]. Let’s take a look at real-life examples of Artificial neural network’s applications in Data Mining: 1. (2009) suggest barriers to progress are related to political, fiscal or cultural reasons and not purely technical. Topics categorized under ‘Organizational Behaviour’ include: behaviour and perspectives, crisis or risk management, clinical and non-clinical decision-making, and resource management (S2 Appendix). Machine Learning and Deep Neural Networks have been used in cutting edge research institutions to find solutions for complex health problems. ANN has been used as part of decision support models to provide health care providers and the health care system with cost-effective solutions to time and resource management [16]. Neural networks can be seen in most places where AI has made steps within the healthcare industry. The overarching goal of this scoping review is to provide a much-needed comprehensive review of the various applications of ANN in health care organizational decision-making at the micro-, meso-, and macro-levels. As per available reports about 65 journals, 413 Conferences, workshops are presently dedicated exclusively to artificial neural networks and about 67138 articles are being published on the current trends in artificial neural networks. No, Is the Subject Area "Decision making" applicable to this article? Data mining is the mathematical core of a larger process of knowledge discovery from databases otherwise referred to as the ‘KDD process [78]. Due to the cross-disciplinary nature of our query, the search strategy was designed to identify literature from multiple databases according to the key disciplines of Health Administration (Medline and Embase), Computer Science (ACM Digital Library and Advanced Technologies & Aerospace Database), and Business and Management (ABI/Inform Global and JSTOR). The global market for health care predictive analytics is projected was valued at USD 1.48 billion in 2015 and expected to grow at a rate of 29.3% (compound annual growth rate) by 2025 [8]. Artificial neural networks for prediction have established themselves as a powerful tool in various applications. 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. Applications of ANN in health care include clinical diagnosis, prediction of cancer, speech recognition, prediction of length of stay [11], image analysis and interpretation [12] (e.g. ANN gained prominence with the publication of a few seminal works including the publication of the backpropagation learning rule for multilayered feed-forward neural networks [22]. Variables selected for data collection were based on bodies of work with similar inquiry and well aligned with the methods of a scoping review. Several limitations of ANN are identified in the literature: they are limited in their ability to explicitly identify possible causal relationships, they are challenging to use in the field, they are prone to over fitting, model development is empirical potentially requiring several attempts to develop an acceptable model [37], and there are methodological issues related to model development [31]. Clinical applications of ANN-based solutions can have implications on the changing role of health care providers as well team dynamics and patterns in workflow. With recent progress in digitized data acquisition, machine learning and computing infrastructure, AI applications are expanding into areas that were previously thought to be only the province of human experts. Keywords:Artificial neural networks, applications, medical science Abstract: Computer technology has been advanced tremendously and … They are connected to other thousand cells by Axons.Stimuli from external environment or inputs from sensory organs are accepted by dendrites. 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. 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 [10]. Neural networks are similar to linear regression models in their nature and use. FeedForward ANN. 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 [99]. 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. These technologies are considered very important. Currently, most of the data in health care is unstructured and difficult to share [107] Wide-scale implementation and adoption of AI service solutions requires strong partnerships between AI technology vendors and health care organizations [107].
