Attention-Based Spatial-Temporal Learning for Enhanced Kidney Abnormality Diagnosis from Ultrasound Images

By Ravikumar Ch. Satyanarayana Nimmala P. Vasanthsena Nenavath Chander R. Sahith

Kidney abnormalities, when detected late, can develop into chronic conditions such as kidney tumors and cardiorenal syndrome. Recently, there has been a move toward automation, especially as it pertains to developing a framework for advanced preprocessing, feature fusion, and hybrid spatial-temporal learning for the detection of the abnormalities in question. For example, Non-Local Means (NLM) filtering for noise reduction, image quality improvements through U-Net kidney segmentation and deep learning-based text annotation removal, as well as robust training through data augmentation and preprocessing ends up facilitating the process. The combination of classical texture and shape descriptors and deep embeddings from a Vision Transformer (ViT) through an attention mechanism allows the model to pinpoint where clinically relevant focus should be. A hybrid CNN-LSTM framework attends to spatial and temporal feature extraction, while attention modules receive the classification output to refine it. The incorporation of weighted binary cross-entropy for handling class imbalance, and of explainable AI, is demonstrated through Integrated Gradients. Experimental results for VATLA show it used advanced algorithms and automation principles in developing systems for all previous performance indicators, while providing evidence of scoring 0.94 in accuracy, 0.92 in precision, 0.95 in recall, and 0.96 in AUC, or area under the curve.

A Novel Approach to Predict High Blood Pressure Using ABF Function

By Satyanarayana Nimmala Ramadevi Y. Ramalingaswamy Cheruku

DOI: https://doi.org/10.5815/ijmecs.2018.07.07, Pub. Date: 8 Jul. 2018

High Blood Pressure (HBP) is a state in the biological system of human beings developed due to physical and psychological changes. Nowadays, it is a most prevalent problem in human beings irrespective of age, place, and profession. The HBP victims are increasing rapidly across the globe. HBP is undiagnosed in the majority of the patients because most of the affected people are not aware of it. To overcome this problem, this paper proposes a new approach that uses ABF (Arterial Blood Flow)-function to predict a person is prone to HBP. In this approach, the impact factor for each attribute is calculated based on the attribute value. Both attribute value and corresponding impact factor are used by ABF function to predict a person is prone to HBP. We experimented proposed approach on real-time data set, which consists of 1100 patient records in the age group between 18 and 65. Our approach outperforms regarding predictive accuracy over j48, Naive Bayes and Rule-based classifiers.
