Concept

Experiment (Deep Attentive Study Session Dropout Prediction in Mobile Learning Environment)

  1. Training Details

The model that gave best AUC score was chosen for the testing phase. The best model had 4 stacked encoder/decoder layers, the latent dimension was 512, the number of heads in multi head attention layer was equal to 8. In this model Xavier initialization was utilized and Adam optimizer was used.

  1. Experiment Results

Besides DAS, LSTM and GRU networks were used and they get as an input ini1+eiin_{i-1} + e_i and ini1=li1+ei1in_{i-1} = l_{i-1} + e_{i-1}. Different sequence size was tried for all of this models: 5 and 25.
