Variational Autoencoder, Random Under-Sampling Boosting and a hybrid approach of the two, are applied to three imbalanced classification data sets with different class imbalances. LÄS MER

3. 2. Predicting the NHL playoffs with Poisson regression

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Jesper Ludvigsen; Adam Grünwald; [2017]
   Nyckelord :Predicting; Poisson regression;

   Sammanfattning : Using historical data from the past two seasons of the National Hockey League, three different prediction models based on Poisson regression are developed. The aim is to determine whether taking into account the recent form of a team as well as data from how they have previously performed against their opponent can help make better predictions of how many goals they will score against this opponent and thereby calculate the likelihood of each outcome.
