A medical checkup of your sleep schedule, and overall sentiment, based on your twitter activity

Given a twitter username, we can calculate the Poisson Probability of the user being awake or asleep at any given time of the day.
With this information, and with the predicted sentiment of the most recent tweets, we can provide a correlation between someone's sleep schedule and their mood.
We hope that this is informative to users in how they can improve their sleep and health.


- Calculated the Poisson Distributions using noisy timestamp data from twitter.
- Approximated the above graph with a binary (on/off) graph to find sleep/wake time.
- Used D3.js + flask to visualize the results.
