Youtube Video Scorer Extension

A chrome extension that scores YouTube videos. It is a useful metric since dislikes and like-to-dislike ratio were removed from YouTube.**

2. Clusters video into groups based on video characteristics.

- Parameters used are combinations and transformations of views, video age, video length, number of comments, number of channel subscribers.
3. Scores the video relative to the other videos in the cluster.
- The score is the percentile of likes-to-view ratio of the video relative to the other videos in the cluster.
- A transformation of the percentile to make the score more intuitive.

How it uses new video data:

- Centroids for clustering and statistics are pre-deployed.
- New video data is used to update the centroids and statistics locally on the browser.
- No data is collected or sent outside the browser.
