To run the baseline experiments:

• Tune hparams: bash scripts/hparams/baseline.sh
  • runs will be saved in runs/hparams_baseline/...
• Extract best hparams from runs: python baseline_hparams.py
  • the best hparams will be saved in visualize/json/baseline.json
• Run training with hparams: bash scripts/baseline/diagonal.sh
  • runs will be saved in runs/5e6_baseline/...
• Run speed tests: bash scripts/speed/baseline.sh
  • runs will be saved in runs/baseline_speed/...
• View results: run interactive ipython in visualize/performance.py
