Howdy Vibecheck

Have you ever thought of predicting what's going on around your social media presence? Do you have many employees taking care of that? Time for automating the vibechecks around your #hashtags.

In this project we tried to identify the key themes around which tweets regarding certain hashtags moved. We also analyzed the important themes along with the emotions associated with those themes.

We created a dashboard in using django to automatically update the data in real time for any organization to see.

Comparison of Cache replacement policies in scattercache

We tried to simulate different cache replacement policies using the Gem5 microarchitectural simulator to determine which one performs better. We used a the Bimodal Re-reference Interval Prediction, First In First Out and Random cache replacement policy in the Last Level Cache. The result is shown in the graph where we could see no replacement policies are performing better on all the cases.
