Application predicting class attendance based on weather¶

Data¶

The application uses datasets containing historical information about the weather on campus and attendance based on JIS card verifications and historical timetable information

• JIS data http://opendata.zcu.cz/Snimace-JIS.html
• Timetable data http://opendata.zcu.cz/Obsazeni-mistnosti.html
• Weather data http://opendata.zcu.cz/Energeticky-dispecink.html

> rozvrh udává kolik lidí tam mělo bejt, plus vzít JISky kolik tam bylo (> můžu mít procentuelní zastoupení) / ?autentizační systém kolik lidí se přihlásilo na pc?

Weather¶

Weather data for model training contains the following information: date, temperature, wind, rain, light in k lux

User can input weather values manually, by selecting options from a form

• values: temperature, wind, rain, sunny/overcast/partly cloudy
  There also is an option for data to be automatically downloaded from a server upon request from the user

Current options for data sources

• RSS from yr.no http://www.kanonbra.com/rss/yr_forecast_rss.php?language=en_US&location=%C4%8Ceahkka/Plze%C5%88sk%C3%BD_Kraj/Plze%C5%88
• RSS from yahoo weather (might be a problem with authorisation) https://www.yahoo.com/news/weather/czech-republic/plze%C5%88sk%C3%BD/plze%C5%88-796166/
• JSON from wttr.in http://wttr.in/Plzen,czechia?format=j1
  App provides the ability to ask for data from today or days in future, and give hourly time specifics (this time will be then approximated into values morning, noon, afternoon, night)
  Again the app will use the following values: temperature, wind, rain, sunny/overcast/partly cloudy

Notes:
Values sunny/overcast/partly cloudy will be translated into lux values
The temperature will be evaluated with certain tolerance (probably determined experimentally)

Datasets¶

Datasets are updated every once in a while with new data. How often update?
-> has to trigger re-training the prediction model, probably do not want to update too often.
Detect when there's new data, check every day? every x days?

Design¶

The output of the Algorithm¶

We need to determine what should be the actual prediction:

• A concrete number of students in a class,
• information about relative occupancy rate.

Motivation¶

TBD

Implementation¶

The application is a mobile app, possibly WebGL app
It is developed in unity which provides more possibilities for export with modifications for given platforms

- prediction model (pluses and minuses ?)
- neuron network
- bayes
