CDAPM

Environment Requirement

The code has been tested running under Python 2.7. The required packages are as follows:

• tensorflow-gpu == 1.14.0
• keras == 2.2.4
• keras_self_attention == 0.49.0
  https://pypi.org/project/keras-self-attention/
• keras_pos_embd == 0.8.0
  https://pypi.org/project/keras-pos-embd/0.8.0/

Project Structure

• /model

  • CDAPM.py #The implementation of CDAPM
  • EmbeddingMatrix.py #The Embedding for text-embedding for a 3-d vector to a 2-d vector
  • mode_normalization.py *# The implementation of Mode Normalization *

• /data # Path of New York Foursquare and Los Angelos Geo-Tweets datasets

  • la_tweets1100000_cikm.txt # Los Angelos Geo-Tweets
  • tweets-cikm.txt # New York Foursquare check-ins
  • venues.txt # New York POIs

• /word_vec

  • glove.twitter.27B.50d.txt # Pretrained Glove word embeddings

• /features # The processed trajectory samples and features by geo_data_decoder.py

  • features&index_seg_gride_fs # New York
  • features&index_seg_gride_la # Los Angelos

• config.py # It contains all the configurations in CDAPM

• eval_tools.py # It contains helper functions and evaluation tools

• geo_data_decoder.py # Preprocessing for both New York Foursquare and Los Angelos Geo-Tweets

• read_features.py # Get the features and samples that model need without running geo_data_decoder.py

• train.py # Training procedure of CDAPM. This is the entrace of CDAPM model.

Usage

we provide the processed features --/features, so we don't need the original dataset you can train and evaluate model :

python train.py
