class libcity.data.dataset.trajectory_encoder.stan_encoder.StanEncoder(config)

Bases: libcity.data.dataset.trajectory_encoder.abstract_trajectory_encoder.AbstractTrajectoryEncoder

encode(uid, trajectories, negative_sample=None)

standard encoder use the same method as DeepMove

Recode poi id. Encode timestamp with its hour.

Parameters

• uid ([type]) – same as AbstractTrajectoryEncoder

• trajectories ([type]) –

  same as AbstractTrajectoryEncoder trajectory1 = [

  (location ID, timestamp, timezone_offset_in_minutes), (location ID, timestamp, timezone_offset_in_minutes), …..

  ]
