Objectives: To propose a model which will pre-process the dataset for the removal of any noise before the training of the network. Methods: Reported literature does not focus on the pre-processing of the dataset before the training of the network. A noise removal scheme called Probabilistic Decision Based Adaptive Improved Trimmed Median Filter (PDAITMF) is implemented as a pre-processing tool before the developed model. The PDAITMF de-noises the dataset. Findings: This supports an effective learning process by the model. The model is trained, validated, and tested with the respective dataset. Accuracy of 0.9401 is achieved without the implementation of PDAITMF, while an accuracy of 0.9841 is achieved when the model uses the dataset processed by PDAITMF. Synchronization is also established between the training and validation graph which seems to be missing when the model uses the dataset without processing through PDAITMF. Novelty: A sharp improvement in accuracy is noted which establishes the effectiveness of the noise removal scheme before the Deep Learning model. The technique may be used to improve the detection accuracy of other acute diseases.
