Hybrid CNN-LSTM for Predicting Diabetes: A Review

Abstract

Background: Diabetes is a common and deadly chronic disease caused by high blood glucose levels that can cause heart problems, neurological damage, and other illnesses. Through the early detection of diabetes, patients can live healthier lives. Many machine learning and deep learning techniques have been applied for noninvasive diabetes prediction. The results of some studies have shown that the CNN-LSTM method, a combination of CNN and LSTM, has good performance for predicting diabetes compared to other deep learning methods. Method: This paper reviews CNN-LSTM-based studies for diabetes prediction. In the CNNLSTM model, the CNN includes convolution and max pooling layers and is applied for feature extraction. The output of the max-pooling layer was fed into the LSTM layer for classification. Discussion: The CNN-LSTM model performed well in extracting hidden features and correlations between physiological variables. Thus, it can be used to predict diabetes. The CNNLSTM model, like other deep neural network architectures, faces challenges such as training on large datasets and biological factors. Using large datasets can further improve the accuracy of detection. Conclusion: The CNN-LSTM model is a promising method for diabetes prediction, and compared with other deep-learning models, it is a reliable method.

“…LSTM finds applications in diverse domains such as handwriting recognition, time series prediction, image analysis, and speech recognition. Currently, LSTM is extensively employed in the domains of handwriting recognition, time series prediction, as well as image and speech recognition ( 57 ). Gers et al identified the limitations of the initial LSTM model and recognized the importance of periodically resetting the memory cell state and selectively forgetting irrelevant old information to accommodate new information storage during the process of information transmission ( 58 ).…”
