Abstract: A patient data management (“PDM”) system is disclosed herein. The PDM can provide doctors with an efficient and accurate means to extract medical diagnostic and treatment information from multi-perspective time based medical data. Further, the PDM provides a means to reduce computer processing time when training a neural network using medical data. In one aspect, a PDM system includes a preprocessor. The preprocessor receives patient data from a computer interface. In one non-limiting example, the preprocessor uses machine learning to extract patterns (“features”) from the data. The preprocessor formats the extracted features into a multidimensional tensor. In one non-limiting example, the PDM system includes a convolutional neural network (“CNN”). The preprocessor provides the tensor to the CNN. The CNN processes the tensor and extracts diagnostic and treatment information.
