Although ANN do not require knowledge of data source, they require large training sets due to the numerous estimated weights involved in computation [26]. Using complex adaptive systems (CAS) theory to understand the functionality of AI can provide critical insights: first, AI enhances adaptability to change by strengthening communication among agents, which in turn fosters rapid collective response to change, and further, AI possesses the potential to generate a collective memory for social systems within an organization [114]. endobj https://doi.org/10.1371/journal.pone.0212356.s001, https://doi.org/10.1371/journal.pone.0212356.s002, https://doi.org/10.1371/journal.pone.0212356.s003, https://doi.org/10.1371/journal.pone.0212356.s004, https://doi.org/10.1371/journal.pone.0212356.s005. 23 0 obj A Convolutional neural network has some similarities to the feed-forward neural network, where the connections between units have weights that determine the influence of one unit on another unit.

Investigation, The integration of ANN with secondary AI and meta-heuristic methods such as fuzzy logic, genetic, bee colony algorithms, or artificial immune systems have been proposed to reduce or eliminate challenges related to ANN (e.g. technique [ 10 ]. grey literature e.g. 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]. Although ANN do not require knowledge of data source, they require large training sets due to the numerous estimated weights involved in computation [26]. Using complex adaptive systems (CAS) theory to understand the functionality of AI can provide critical insights: first, AI enhances adaptability to change by strengthening communication among agents, which in turn fosters rapid collective response to change, and further, AI possesses the potential to generate a collective memory for social systems within an organization [114]. endobj https://doi.org/10.1371/journal.pone.0212356.s001, https://doi.org/10.1371/journal.pone.0212356.s002, https://doi.org/10.1371/journal.pone.0212356.s003, https://doi.org/10.1371/journal.pone.0212356.s004, https://doi.org/10.1371/journal.pone.0212356.s005. 23 0 obj A Convolutional neural network has some similarities to the feed-forward neural network, where the connections between units have weights that determine the influence of one unit on another unit. Applications of hybrid intelligent systems include robotics, medical diagnosis, speech/natural language understanding, monitoring of manufacturing processes. They are comprised of input (independent or predictor variable) and output (dependent or outcome variable) nodes, use connection weights (regression coefficients), bias weight (intercept parameters) and cross-entropy (maximum likelihood estimation) to learn or train (parameter estimation) a model [31]. Health care organizations are leveraging machine-learning techniques, such as artificial neural networks (ANN), to improve delivery of care at a reduced cost. , is the Subject Area `` artificial neural network impacting the healthcare applications of convolutional neural network [ ].
