After running `run_drl_improvements.sh`, this script reads all
|
|
results_improve/*/drl_snr_sweep.csv, picks the best-performing
|
|
variant, and emits:
|
|
1. A drop-in LaTeX paragraph for §Results (CosSim table).
|
|
2. Updated abstract numbers (recovery fraction; MAML-gap closure).
|
|
3. A new row for Table II (hyperparameters) if log_std_init != -1.0
|
|
produced the best result.
|
|
4. A command line to run update_fig_with_improved.py which
|
|
overlays the best variant on Fig 3(b).
|
|
|
|
All output is written to results_improve/paper_updates.txt and
|
|
printed to stdout.
