This paper presents TD-AC which is an effective algorithm for the truth discovery problem when the attributes over data are structurally correlated. We build our procedure on an abstract representation of the truth in the data, the k-means clustering technique and the silhouette measure to automatically find an optimal partitioning of the input …

I recently tried designing a Data Warehouse for Zomato/Swiggy, one of the leading online food delivery platforms. This project has provided me with invaluable hands-on experience, allowing me to apply my skills and knowledge in a real-world scenario.

Three business analytics case studies were undertaken, encompassing market basket analysis, customer segmentation, and campaign management.

A comprehensive analysis in R of weak signal propagation within the WSPR network, focusing on the impact of distance, frequency, and power on signal-to-noise ratios. The project includes data cleaning, statistical analysis, and linear regression modeling to predict signal reception quality and understand the factors influencing signal propagation.

Implementation of data partitioning techniques based on several multi-dimensional data structures. Benchmarking on range queries.
