Scoliosis Training Change Log

This file is the single run-by-run changelog for Scoliosis1K training and evaluation in this repo.

Use it for:

• what changed between runs
• which dataset/config/checkpoint was used
• what the resulting metrics were
• whether a run is still in progress

Conventions

• Add one entry before launching a new training run.
• Update the same entry after training/eval completes.
• Record only the delta from the previous relevant run, not a full config dump.
• For skeleton-map control runs, use plain-text ScoNet-MT-ske naming in the notes even though the code class is ScoNet.

Current best skeleton baseline

Current best ScoNet-MT-ske-style result:

• practical best on the easier 1:1:2 split:
  • ScoNet_skeleton_112_sigma15_joint8_bodyonly_plaince_bridge_1gpu_10k at 7000
  • 83.16 Acc / 68.24 Prec / 80.02 Rec / 68.47 F1
• best result retained on the harder 1:1:8 split:
  • ScoNet_skeleton_118_sigma15_joint8_sharedalign_2gpu_bs12x8
  • 50.47 Acc / 69.31 Prec / 54.58 Rec / 48.63 F1

Notes

• ckpt/ScoNet-20000-better.pt is intentionally not listed here because it is a silhouette checkpoint, not a skeleton-map run.
• DRF runs are included because they are part of the same reproduction/debugging loop, but this log should stay focused on train/eval changes, not broader code refactors.
• The long ScoNet_skeleton_118_sigma15_joint8_sharedalign_nocut_adamw_1gpu_bs8x8 run was intentionally interrupted and superseded by the shorter proxy run once fast-iteration support was added.
• The geometry-fixed proxy run fit the train split quickly but did not produce a stable proxy validation curve, so it should not be promoted to a full 20k run.
• The weighted-CE proxy briefly improved the proxy peak at 1000 iterations, but it also collapsed afterward, so class weighting alone is not a sufficient fix for the skeleton branch.
• The body-only proxy improved the early 500-iteration proxy result relative to some earlier runs, but it still collapsed badly after 1000, so removing face/head structure alone is also not a sufficient fix.
• Combining body-only with weighted CE gave the best 500-iteration proxy seen so far (68.75 Acc / 49.59 F1 on the fixed 128-sequence subset), but it still degraded substantially by 1000+, which points more toward schedule/imbalance dynamics than a single missing representation tweak.
• Full-test check on retained checkpoints from the combined body-only + weighted CE run did not confirm a simple early-stop win: the retained 1000 checkpoint scored 56.61 Acc / 52.11 Prec / 34.15 Rec / 25.61 F1 on the full test split, while 2000 scored 41.52 Acc / 56.75 Prec / 54.75 Rec / 40.09 F1. That means the small proxy subset is useful for screening but not reliable enough to choose the final stopping point by itself.
• The 1:1:2 bridge run is the strongest evidence so far that the skeleton branch is learnable: with the current best skeleton recipe (body-only + weighted CE), the full test score at 7000 reached 81.82 Acc / 66.21 Prec / 88.50 Rec / 65.96 F1. That still trails the ScoNet paper’s stronger 1:1:2 result, but it is dramatically better than the 1:1:8 skeleton runs and makes class distribution a first-order factor in the reproduction gap.
• Removing weighted CE on the 1:1:2 bridge improved the current best full-test result further: body-only + plain CE reached 83.16 Acc / 68.24 Prec / 80.02 Rec / 68.47 F1 at 7000, so weighted CE does not currently look beneficial on the easier split.
