Portfolio

9198426
It was a spatial temporal data analysis project on the Beijing taxi data set using Java. Mined taxi trajectory data and identified taxi drivers by data linkage. • Performed the ETL process on the Beijing taxi data; transformed data using dimension reduction (e.g. CUT, PCA); applied multi-layer grid-based representation on the data set. • Applied Weighted R-tree as the index structure on the grid-based data to speed up the data transformation process. • Did the user identification by using KNN based on the transformed data; speeded up the KNN process by pruning strategy on the R-tree index structure; implemented Re-ranking strategy on the initial KNN algorithm to improve accuracy. • Reached a 96% accuracy by using a grid-based data representation and KNN linking algorithm; analyzed the influence of different methods and parameter values on the computational complexity and accuracy. • Visualized the performance and outcome; formed the report.
