Stage-aware disentangled conditional VAE for interpretable prediction of cognitive decline Sergey Yarushev, S. Neelakandan, N. Banupriya, S. Velmurugan Discover Computing, 2026 Neurodegenerative diseases like Alzheimer’s, Parkinson’s, vascular dementia, and frontotemporal dementia are difficult to detect early due to noisy or missing Mini-Mental State Examination (MMSE) data and uninterpretable prediction models. A Disentangled Conditional Variational Autoencoder (D-CVAE) Fusion model with a novel stage-aligned disentanglement loss addresses these issues. Clinically interpretable representations are achieved by separating cognitive decline components from other latent variations. The model reconstructs lost MMSE data and improves feature representation by conditioning the encoder-decoder architecture on cognitive stage. Using disentangled latent embeddings, an integrated Multi-Layer Perceptron (MLP) classifier accurately identifies cognitive impairment levels from no impairment to moderate impairment. Our D-CVAE Fusion model has 94.52% accuracy, resilience with 30% missing data, and clinically significant latent dimensions (e.g. z₁ shows strong correlation with MMSE score, r = − 0.94). Clinical decision support systems for cognitive evaluation and early-stage neurodegenerative disease diagnosis can use the suggested paradigm with confidence and interpretability.
ERP Insights and Truncated SVD in Conjunction with Dual-Tree Complex Wavelet Transform and Multi-View Hypergraph Neural Networks for Cognitive Distortion Analysis N. Banupriya, Neelakandan Subramani, M. Prakash, S. Velmurugan International Journal of Computational Intelligence Systems, 2025 Multi-modal EEG data analysis requires sophisticated methods for accurate prediction in the critical area of cognitive depression study in neuroscience. With the help of Multi-View Hypergraph Neural Networks (MV-HGNN) and Dual-Tree Complex Wavelet Transform (DT-CWT), a novel framework for enhancing cognitive distortion analysis is provided today. The initial stage of the procedure, DT-CWT, captures EEG signals and extracts the crucial frequency characteristics (gamma, delta, theta, beta, and alpha). Truncated singular value decomposition, or SVD, thereby reduces noise although preserving significant features. To identify task-related cognitive responses, Event-Related Potential (ERP) is used. The data is arranged into a multi-view framework following processing, which records multiple perspectives such as task-specific responses, frequency patterns, and temporal trends. To enable MV-HGNN to recognize complex cognitive patterns, a hypergraph is then constructed to mimic the complex relationships between various viewpoints. The final category predicts cognitive distortion. According on experimental data, the proposed method outperforms traditional deep learning models and delivers improved accuracy. This work shows that integrating multi-resolution feature extraction, dimensionality reduction, and hypergraph learning is effective for EEG-based cognitive distortion analysis.
Enhanced Stroke Detection in CT Imaging via DeepLabV3+ and Multi-Scale Feature Learning T. Aparna, Neelakandan, T.Sethukarasi, D.PaulRaj, A.S.Thillai Valavan Proceedings IEEE International Conference on Advanced Video and Signal Based Surveillance Avss, 2025 Strokes still stand as one of the most common, as well as fatal, causes of disability. Prompt, accurate diagnosis is essential for recovery, and effective treatment depends on it. With radiologists being the prime career involved in CT or MRI interpretation, this may take much time and be prone to inaccuracy. Deep learning mainly promotes the concept of a total automation boost to the diagnostic capabilities of medical imaging, proving to be a quick answer. The Stroke Detective framework, which utilizes deep learning algorithms, classifies whether a stroke on a CT scan is ischemic versus hemorrhagic, as well as the specific location of the damage within the brain that resulted in hemiplegia. In the pursuit of achieving pixel-wise segmentation of brain images (CT and MRI), the Deep Lab version 3 (DeepLabV3) continues its performance on precise segmentation of stroke-invoked areas. This segmentation, by measuring and analyzing the affected areas, is such a tool for stroke diagnosis, which can directly impact patient outcomes and therapeutic approaches. DeepLabV3: This encoder-decoder architecture, which employs ASPP and is built upon a deep convolutional neural network (CNN), is thought to be a very promising way to enhance stroke identification and segmentation in brain scans. To accurately segment stroke areas in complex brain images, DeepLabV3 recommends an encoder-decoder architecture structure that enables the model to identify details at the edges of lesions. The DeepLabV3+ with ASPP Modules permits the model to pay attention to both large and minute brain lesions. The ASPP introduced by the model enables successful retrieval of contextual information about multi-scales by using atrous (or dilated) convolutions with increasing rates. The ASPP captures image features at multiple scales, hence helping us segment those lesions that are challenging to identify owing to subtle differences in their size and texture. Various experiments have shown that the DeepLabV3 model outperforms the current best methods. The model demonstrates superior potential for lesion localization and boundary accuracy on stroke MRI and CT imaging datasets in comparison with patchy, dreary, repetitive models, thus assisting lesion segmentation. Advocates the integration of the DeepLabV3+ and ASPP for stroke detection and segmentation and, hence, will provide a functional tool to enhance diagnostic precision and facilitate timely intervention decisions by a physician.
Comparative analysis of basic operations of helib and microsoft seal libraries for cloud computing Maria Lapina, Subramani Neelakandan, Maxim Donchenko, Dmitry Ardeev, Nikita Boykov Nature Inspired Optimization Algorithms for Cyber Physical Systems, 2024 The following encryption types are considered: partially, somewhat and fully homomorphic. Each type differs in the arithmetic operations provided and the number of their execution. Basic operations in homomorphic encryption are considered: addition, multiplication, encryption and decryption. The three homomorphic encryption libraries OpenFHE, HElib, and Microsoft SEAl are examined. OpenFHE provides maximum flexibility by supporting a variety of homomorphic encryption methods and is therefore suitable for a variety of applications. HElib focuses on support for BGV schemes. Microsoft SEAL focuses on ease of use and high performance and supports BFV and CKKS schemes. Two benchmarks were implemented to analyze basic operations and solve the quadratic equation in encrypted form in HElib and Microsoft SEAL libraries. The results showed the advantage of HElib library in the execution time of all operations compared to Microsoft SEAL.
Provably secure data selective sharing scheme with cloud-based decentralized trust management systems S. Velmurugan, M. Prakash, S. Neelakandan, Arun Radhakrishnan Journal of Cloud Computing, 2024 The smart collection and sharing of data is an important part of cloud-based systems, since huge amounts of data are being created all the time. This feature allows users to distribute data to particular recipients, while also allowing data proprietors to selectively grant access to their data to users. Ensuring data security and privacy is a formidable task when selective data is acquired and exchanged. One potential issue that emerges is the risk that data may be transmitted by cloud servers to unauthorized users or individuals who have no interest in the particular data or user interests. The prior research lacks comprehensive solutions for balancing security, privacy, and usability in secure data selective sharing schemes inside Cloud-Based decentralized trust management systems. Motivating factors for settling this gap contain growing concerns concerning data privacy, the necessity for scalable and interoperable frameworks, and the increasing dependency on cloud services for data storage and sharing, which necessitates robust and user-friendly mechanisms for secure data management. An effective and obviously secure data selective sharing and acquisition mechanism for cloud-based systems is proposed in this work. We specifically start by important a common problematic related to the selective collection and distribution of data in cloud-based systems. To address these issues, this study proposes a Cloud-based Decentralized Trust Management System (DTMS)-connected Efficient, Provably Secure Data Selection Sharing Scheme (EPSDSS). The EPSDSS approach employs attribute-based encryption (ABE) and proxy re-encryption (PRE) to provide fine-grained access control over shared data. A decentralized trust management system provides participant dependability and accountability while mitigating the dangers of centralized trust models. The EPSDSS-PRE paradigm would allow data owners to regulate granular access while allowing users to customize data collection without disclosing their preferences. In our strategy, the EPSDSS recognizes shared data and generates short fingerprints for information that can elude detection before cloud storage. DTMS also computes user trustworthiness and improves user behaviour administration. Our research demonstrates that it’s able to deliver trustworthy and safe data sharing features in cloud-based environments, making it a viable option for enterprises seeking to protect sensitive data while maximizing collaboration and utilization of resources.
