Model Concerns
- Time to complete one trajectory is different across participants.
- Trajectory is similar but the way participants walk is different.
- Different trajectories
- Each trajectory consists of 4 trials for each participant
- Classification of participants using navigation data
PRELIMINARY RESULTS
200 data points sampled from each trials
1392 trials in total (29 participants * 48 trials)
Model : ResNet 18
Predictors : Location X, Location Y and Heading Direction
