simulation in "Trajectory clustering via deep representation learning"

Tensorflow = 0.11.0rc0, pandas = 0.19.0, sklearn = 0.17.1 traj_dist = https://github.com/maikol-solis/trajectory_distance

Generating the synthetic trajectories 'sim_trajectories' in /simulated_data/. Here, we only generate 30 trajectories as the sample.

Embed each trajectory to a fixed-length vector utiziling our framework. Five files is generated in /simulated_data/

• sim_trajectories_complete : Trajectories after attributes completion.
• sim_trajectories_feas : Elementary features computed by each pair of continuous records
• sim_behavior_sequences : Behavior sequence generated sliding windows and Feature Extraction Layer
• sim_normal_behavior_sequences : Moving behavior sequence after normalizaion
• sim_traj_vec_normal_reverse : Vector of trajectories generated by Seq2Seq Auto-Encoder Layer

Four distance based trajectory clustering methods(DTW, EDR, LCSS, Hausdorff) were compared with our framwork. After compution, distance matrixs are generated in /distances/.
