Requirements

• Python 3.6
• Tensorflow 1.2.1
• docopt 0.6.2
• numpy 1.13.3
• sklearn 0.18.1
• pandas 0.20.1
• scipy 1.0.0

How to Run

1. unzip dataset.7z
2. Compute the aspect-level similarity matrix with the matlab code
3. Run the model with the python code acf.py

example:

 python ./acf.py ../dataset/amazon/ amovie --mat "U.UIU,I.IUI,U.UICIU,I.ICI" --epochs 40 --last_layer_size 64 --batch_size 1024 --num_of_neg 10 --learn_rate 0.00005 --num_of_layers 2 --mat_select median
