In computer vision, the convolutional neural network (CNN) is a very popular model used for emotion recognition. It has been successfully applied to detect various objects in digital images with remarkable accuracy. In this paper, we extracted learned features from a pre-trained CNN and evaluated different machine learning (ML) algorithms to perform classification. Our research looks at the impact of replacing the standard SoftMax classifier with other ML algorithms by applying them to the FC6, FC7, and FC8 layers of Deep Convolutional Neural Networks (DCNNs). Experiments were conducted on two well-known CNN architectures, AlexNet and VGG-16, using a dataset of masked facial expressions (MLF-W-FER dataset). The results of our experiments demonstrate that Support Vector Machine (SVM) and Ensemble classifiers outperform the SoftMax classifier on both AlexNet and VGG-16 architectures. These algorithms were able to achieve improved accuracy of between 7% and 9% on each layer, suggesting that replacing the classifier in each layer of a DCNN with SVM or ensemble classifiers can be an efficient method for enhancing image classification performance. Overall, our research demonstrates the potential for combining the strengths of CNNs and other machine learning (ML) algorithms to achieve better results in emotion recognition tasks. By extracting learned features from pre-trained CNNs and applying a variety of classifiers, we provide a framework for investigating alternative methods to improve the accuracy of image classification.
As one gets older, the likelihood of this happening increases. Minor cognitive impairment may serve as an early warning sign of dementia, according to popular belief. Some of the claims stated here are not supported by sources. Alzheimer’s disease and other kinds of neurodegeneration frequently manifest their first signs as dementia. People with poor intellect may struggle to discern between a sick and a healthy reference group. Our system can efficiently extract as much data from the scan as was feasible by using the entire three-dimensional magnetic resonance imaging images as input. The multichannel meta-discourse learning approach improves the system’s and network’s categorization abilities as well as their ability to make large generalizations. One option for achieving this goal is to broaden the number of available educational routes. The binarization loss and the unchaperoned contrastive loss are combined into a single loss to achieve this. Combining the binarization loss and the unchaperoned contrastive loss results is a realistic method that may help you achieve your aim. We ran many experiments using the acquired data to put our system through its paces and verify its value. These findings show that our method might be used to diagnose Alzheimer's disease, dementia, and mild cognitive impairment (MCI). Individual adaptation to their preferred mode of learning is one method that, if implemented, has the potential to significantly boost the value of educational experiences. By creating a fresh perspective on education, the network may be able to assist us in classifying data in a more accurate and appropriate manner in a wider range of scenarios.KeywordsAlzheimer’s diseaseMild cognitive impairmentMagnetic resonance imagingRegions of interestDeep learning
Convolutional neural networks (CNN) can no longer make a significant contribution to Alzheimer’s disease diagnosis because there is insufficient data to work with. We have built a cutting-edge deep learning system and are currently putting it to use to increase the effectiveness of the work we are doing to achieve this goal. To achieve the highest level of performance, we combine the advantages of fully stacked bidirectional long short-term memory (FSBi-LSTM) with those of three-dimensional convolutional neural networks. These two methods of data storage are stacked one on top of the other. Before interpreting the MRI and PET images, it is critical to train a three-dimensional convolutional neural network. This must be completed to proceed to the next stage. The essential qualities of the deep features can be agreed upon. Before any further inquiry into the matter can proceed, this must be done. Here is only one example of how this method may be applied. Even if only one individual is made aware of this, the ramifications might be terrible. Lastly, we compared our findings to those of an Alzheimer’s disease neuroimaging research study to show definitively that our technique is beneficial in Alzheimer’s disease management. According to our observations, our approach surpasses other theoretically comparable algorithms published in academic literature. These algorithms were evaluated based on their ability to tackle the same issue. This is true regardless of whether our technique is technically equivalent to other published methods: cases of pMCI can be distinguished from NC with a success rate of 94.82%; cases of sMCI can be distinguished from NC with an 86.30% success rate; and cases of Alzheimer’s Disease (AD) can be distinguished from NC with an 86.30% success rate. This result was obtained despite the fact that there was inadequate imaging evidence to back it up.KeywordsConvolution neural networkFully stacked bidirectionalLong short-term memoryDeep learningRecurrent neural networks
