Project Functionality

  • Terrarium
    • After logging in, users are presented with a "terrarium" which slowly "dies" over time if they do not keep their health score above pre-determined values
  • Health Score
    • The health score is a rounded value reprsented by ((Diet Score + Meditation Score + Exercise Score) / 3)
    • This score represents the user's "overall" scoring and it slowly decreases over time as the scores in each category decrease
    • The user can complete tasks in each category to increase this score, but doing tasks in one category can only get, at most, 1/3 of this overall score
  • Recommendation Categories
    • Each of these categories has a score which decreases with time. This score can be increased throughout the day by completing the recommended tasks in each.
    • Diet Recommendations
      • Diet recommednations use the Spoonacular API to recommend a recipe to make
    • Meditation Recommendations
      • Meditation uses a Random Forest Classifier to recommend a music genre to meditate to. This cateogry then filters down to one song, and recommends a location to meditate at based off of user context
    • Exercise Recommendations
      • Exercise uses a Gradient Boosting Regressor to recommend an intensity level of exercise to complete. A final exercise recommendation is then made based off of user context and a user model. This user model incorporates data about the user's previous exercise behavior, the equipment they have, and their access to a gym
