This research focuses on addressing the challenges of missing data in time-series and multi-constraint datasets. By optimizing imputation methods, the study enhances prediction accuracy and reliability for applications in fields like weather forecasting and financial analytics.
The project was inspired by the increasing importance of accurate data-driven decision-making, where incomplete datasets often lead to compromised predictions. The goal was to design a novel solution that integrates machine learning and algorithmic optimizations to handle complex datasets effectively.
Dynamic Imputation with MICE: Combined the MICE (Multiple Imputation by Chained Equations) model with optimized stochastic matrix multiplication using Strassen’s algorithm to enhance the accuracy of imputed values.
Multi-Constraint Imputation: Proposed and implemented a sequence-analysis-based approach to optimize algorithm pairing and sequencing for datasets with multiple incomplete columns.
Novel Research Outcome: Identified new strategies to improve data handling for scenarios where traditional imputation methods fall short, leading to better results in predictive analytics.
Machine Learning Models: MICE for imputation and predictive analysis.
Algorithms: Strassen’s algorithm for efficient matrix computations.
Languages & Libraries: Python, NumPy, pandas, and scikit-learn for data processing and model implementation.
