cascade-adain-transplant-v24

Fork of cascade-v23-poolaligned with series-level AdaIN transplant — the Cascade-legal analogue of TSFM activation transplantation.

Why not model-side transplant?

Cascade locks Toto2 (architecture, init, forward). Miners only ship a DataGenerator. Layer hooks / (A_l) interventions are impossible under the contract. This artifact instead treats each univariate series as a stand-in for (A_l) and transplants time-averaged (or rolling) ((\mu,\sigma)).

Mechanism

For a fraction augment.adain_transplant of fixed-length series in each chunk:

Pick a style series from the same chunk (different index).
AdaIN the target: tilde = ((tgt - μ_tgt)/(σ_tgt+ε)) * σ_style + μ_style
Optional adain_blend < 1 mixes transplanted with original.
Optional adain_window > 0 uses rolling stats (local signature implant).

TSMixup remains (slightly lowered to 0.04) as a complementary convex mix; AdaIN is a stats swap, not an average.

Config knobs

key	default	meaning
`augment.adain_transplant`	0.12	fraction of series receiving a transplant
`augment.adain_window`	0	0 = global stats; >0 = rolling window length
`augment.adain_blend`	1.0	1 = full transplant; 0 = identity

Validate

bash

python3 -m cascade.miner.cli verify ./_top_codes/cascade-v24-adain-transplant --chain-toml chain.toml
cascade score ./_top_codes/cascade-v24-adain-transplant --pool-dir ./cascade-eval-pool/snapshots/2026-07-21 --device cpu

A/B against v23 on the same pool before promoting.
