About Pensive-PPO
This is an easy TensorFlow implementation of Pensieve[1]. In detail, we trained Pensieve via PPO rather than A3C. It’s a stable version, which has already prepared the training set and the test set, and you can run the repo easily: just type
python train.py
instead. Results will be evaluated on the test set (from HSDPA) every 300 epochs.
Experimental Results
We reported the training curve of entropy weight beta, reward, and entropy respectively. Results were evaluated over the Oboe network traces.
Tips: the orange curve: pensieve-ppo; the blue curve: pensieve-a2c
Pretrained Model
Furthermore, we have also added the pretrained model in https://github.com/godka/Pensieve-PPO/tree/master/src/pretrain
The model improves 7.03% (0.924->0.989) on average QoE compared with the original Pensieve model [1].
