image-segmentation-by-correlation-clustering

This is the project that we did for the Computer Vision course at Stony Brook University. It is a learning based method where the number of clusters do not have to be specified from the beginning. Image Segmentation by Correlation Clustering gave us extremely good results with Boundary displacement Error as low as 4.85 compared to 10.81 in the work "Higher-Order Correlation Clustering for Image Segmentation"

opinion-spam-detection

In this project, we used a novel approach to detect opinion Spam by modelling the data as a Dynamic Graph. Previous approaches to the problem of opinion Spam Detection have made use of a Static Graph. Our novel approach lets us get interesting Role Transition Patterns. We are also able to predict the possibility of future Spam using Personalized PageRank.
