neurallaplacecontrol's Introduction

Neural Laplace Control for Continuous-time Delayed Systems (Code)

arXiv License: MIT code style

This repository is the official implementation of Neural Laplace Control for Continuous-time Delayed Systems.

  1. Run/Follow steps in install.sh
  2. Replicate experimental results by running and configuring run_exp_multi.py.
    python run_exp_multi.py
  3. Process the output log file using process_logs.py by updating the LOG_PATH variable to point to the recently generated log file.
    python process_results/process_logs.py

Retraining

To retrain all models from scratch (much slower), set the following variables to True in run_exp_multi.py before running it:

RETRAIN = True
FORCE_RETRAIN = True
