PROJECTS

1. Unsupervised Deconvolution of Different Datasets using Improved Convex Analysis of Mixtures (CAM): To detect latent sources, their respective source signature genes/metabolites, and their relevant concentration patterns between healthy control and patients for the following datasets: CAD GWAS metabolomic datasets ('Mesa' and 'Rotterdam'), GPAA proteomics, and GPAA RNAseq.

2. Missing Data Imputation of Different Datasets: To impute the missing values for the Fresh frozen LAD45, AA paired Trizol data, and the LAD Trizol data. Further, to conduct a comparative analysis of different missing data imputation methods.

3. Application of Cosine-based One-Sample Test (COT) to Detect Marker Genes Among Many Subtypes: To enhance COT for downregulated signature genes (DSGs) along with upregulated expressed genes (SGs). COT-based detection of both condition-specific SGs and DSGs for the following datasets: GPAA RNAseq, GPAA proteomics, Edinburgh.

4. Integrating Information Set Theory with Deep Learning Principles to Improve Noisy Pattern Classification: To address the critical problem of the absence of robust deep learning models, we propose Information-Set Deep Learning (ISDL) architectures with four variants by integrating information set theory and deep learning principles.
5. Text Independent Speaker Identification: The aim of this project is to develop robust speaker recognition models. Three distinct approaches were developed for this purpose.

6. Pattern Similarity Based Clustering: Two pattern similarity-based techniques were developed for data clustering. The project demonstrates that distance functions are not always sufficient for data clustering, as strong correlations may exist among data vectors even if they are physically distant from each other.

7. Time Series Prediction: To predict chaotic time series data.

8. Solar Radiation Estimation: To estimate solar radiation using machine learning techniques and meteorological data.
9. Brain Fingerprinting: Detection of Physiological Based Concealed Information in the Brain of Culprit using Machine Learning Techniques : The project aimed to use electroencephalogram (EEG) data for the forensic application of identifying concealed information in the human brain.
