feat(benchmarks): efficiency sweep MEASURED — half model dominates full reference
Compact WiFlow-STD variants on the same data/split/protocol: half (843,834 params, 0.38x) strictly dominates the 2.23M reference (PCK@20 96.62 vs 96.61, PCK@50 99.47 vs 99.11, MPJPE 0.00898 vs 0.0094) — the published architecture is over-parameterized for its own benchmark. quarter (338k) 96.05%; tiny (56,290 params, 1/39.5) holds 94.11% — a ~220KB fp32 edge candidate. In-domain caveats recorded; cross-domain untested. Co-Authored-By: claude-flow <ruv@ruv.net>

## Efficiency sweep (MEASURED, overnight 2026-06-10/11)

|

ADR-152 beyond-SOTA track: compact purpose-built variants of the WiFlow-STD
|
||||
architecture, trained from scratch on the same cleaned dataset, identical
|
||||
seed-42 file-level split, loss and protocol as the measurement-(a) reference
|
||||
(fp32, batch 64, ≤50 epochs, patience 5; RTX 5080, ~22–29 min/variant).
|
||||
Variant transforms are pure channel/group/stride scalings of an
|
||||
architecture-exact parameterized model (validated: reproduces 2,225,042 params
|
||||
at the reference config). Scripts: `remote/sweep/`; raw:
|
||||
`results/efficiency_sweep.jsonl`; checkpoints `results/{half,quarter,tiny}_best.pth`
|
||||
(gitignored).

Findings:
|
||||
|
||||
- **The half model (843k params) strictly dominates the full reference** on
|
||||
this dataset — equal PCK@20, better PCK@50 and MPJPE, converges in fewer
|
||||
epochs. The published 2.23M architecture is over-parameterized for its own
|
||||
benchmark.
|
||||
- **tiny (56k params, 1/39.5) holds 94.11% PCK@20** — a ~220 KB fp32 /
|
||||
~60 KB int8-class model in reach of severely constrained edge targets,
|
||||
at −2.5 pt from the full reference.
|
||||
- Caveats: in-domain (5-subject random-file split) like every number on this
|
||||
dataset; single run per variant; corruption-free test subset (52,560).
|
||||
Cross-domain behavior of compact variants is untested — ADR-150's evidence
|
||||
says capacity *hurts* cross-subject, so the compact end may generalize no
|
||||
worse, but that is a hypothesis, not a measurement.

"""Configurable compact variants of the WiFlow-STD pose model (ADR-152 efficiency sweep).

|

This is a parameterized copy of upstream models/{pose_model,tcn,convnet,attention}.py
|
||||
(DY2434/WiFlow @ 06899d29, Apache-2.0). upstream/ is NOT modified. Deviations from
|
||||
upstream, all forced by shrinking channels and documented per variant in run_sweep.py:
|
||||
|
||||
1. TCN grouped-conv groups: upstream hardcodes groups=20, which does not divide
|
||||
the compact channel counts (e.g. 270, 135, 85). Rule here:
|
||||
- groups_mode='gcd20': per-conv groups = gcd(channels, 20) (== 20 wherever
|
||||
upstream's choice is valid, incl. the 540-ch input conv; falls back to the
|
||||
largest common divisor with 20 otherwise).
|
||||
- groups_mode='depthwise': groups = channels (tiny variant only).
|
||||
2. Conv2d downsampling strides: upstream uses 4 stride-(1,2) blocks because
|
||||
240/2^4 = 15 == n_keypoints. With smaller TCN output widths that would leave
|
||||
<15 rows and AdaptiveAvgPool2d((15,1)) would duplicate rows across keypoints.
|
||||
Rule: halve the width only while the result stays >= 15 (stride-2 blocks
|
||||
first, stride-1 after). Full model: 240 -> 4 halvings = upstream exactly.
|
||||
3. input_pw_groups (tiny only): the dense 540->c pointwise + residual downsample
|
||||
in TCN block 1 cost 2*540*c params (a ~117k floor that alone exceeds the
|
||||
tiny <100k budget). tiny groups these two convs (groups=4; 4 | gcd(540, 68)).
|
||||
4. Decoder mid-channels: upstream 64->32; here c_last -> max(c_last // 2, 4).

"""WiFlow-STD compact-variant efficiency sweep (ADR-152) — sequential overnight runner.
|
||||
|
||||
Trains compact variants of the upstream WiFlow-STD architecture on the same
|
||||
data/split as the full-size reference retraining (seed 42, file-level 70/15/15,
|
||||
upstream dataset.py) and evaluates PCK@10..50 + MPJPE on the full test split and
|
||||
the corruption-free test subset (file indices < 487).
|
||||
|
||||
Training mirrors upstream run.py/train.py defaults except:
|
||||
- fp32 only (no fp16 autocast / GradScaler — avoids the BN-poisoning trap
|
||||
documented in RESULTS.md defect 5; data on disk is already cleaned).
|
||||
- batch 64 (kept modest: another GPU job may share the 16 GB card tonight).
|
||||
- scheduler + early stopping keyed on val MPJPE (upstream early-stops on val MPE
|
||||
with patience 5; same here).
|
||||
|
||||
Usage:
|
||||
venv/bin/python sweep/run_sweep.py --dry-run # param counts only
|
||||
nohup venv/bin/python sweep/run_sweep.py > sweep/sweep.log 2>&1 &
|
||||
|

Idempotent: variants already present in sweep/results.jsonl are skipped.
