In particular, a three-layer Recurrent Neural Network was used in conjunction with the aggregated EHRs of about 127,149 patients from a medical data warehouse. The result forms a key component of an application we name PANNACEA. We evaluated this neural network in the context of competing neural network architectures, comparing the performance of multilayer perceptrons, convolutional neural networks, and recurrent neural networks in relation to the dataset under investigation. We performed evaluation our program to successfully classify the suitability of these patients to the medical service offered based upon a single medical episode.||Funding Details:||Science Foundation Ireland||metadata.dc.description.othersponsorship:||Insight Research Centre||Type of material:||Conference Publication||Start page:||245||End page:||251||Copyright (published version):||2018 CSREA Press||Keywords:||Bioinformatics; Artificial neural networks; Mining text; Semi-structured data||DOI:||10.xxx||Other versions:||https://csce.ucmss.com/cr/books/2018/ConferenceReport?ConferenceKey=ICD||Language:||en||Status of Item:||Peer reviewed||Is part of:||Stahlbock, R., Weiss, G.M., Abou-Nasr, M.
