Hey everyone!
I recenlty developed a chrome browser extension which predicts leetcode rating after participating in contests. It uses leetcode's rating prediction algorithm(https://leetcode.com/discuss/general-discussion/468851/New-Contest-Rating-Algorithm-It's-HERE!/) to predict ratings and show the predictions on offical leetcode website right after the completion of contest.
The accuracy of rating prediction is quite good. These are the results I got when it was tested on a contest:
| Measure | Value |
|---|---|
| MSE | 167.7947072739485 |
| R-squared | 0.9988091420057561 |
Thanks!
