Abstract: Healthcare informatics is one of the major concern domains in the processing of medical imaging for the diagnosis and treatment of brain tumours all over the world. Timely diagnosis of abnormal structures in brain tumours helps the clinical applications, medicines, doctors etc. in processing and analysing the medical imaging. The multi-class image classification of brain tumours faces challenges such as the scaling of large dataset, training of image datasets, efficiency, accuracy etc. EfficientNetB3 neural network scales the images in three dimensions resulting in improved accuracy. The novel neural network framework utilizes the optimization of an ensembled architecture of EfficientNetB3 with U-Net for MRI images which applies a semantic segmentation model for pre-trained backbone networks. The proposed neural model operates on a substantial network which will adapt the robustness by capturing the extraction of features in the U-Net encoder. The decoder will be enabling pixel-level localization at the definite precision level by an average ensemble of segmentation models. The ensembled pre-trained models will provide better training and prediction of abnormal structures in MRI images and thresholds for multi-classification of medical image visualization. The proposed model results in mean accuracy of 99.24 on the Kaggle dataset with 3064 images with a mean Dice score coefficient (DSC) of 0.9124 which is being compared with two state-of-art neural models.
