Duplicate positional encoding
Check R25. Runs in the editor as you build, in CI through the
GitHub Action, and over the wire at
POST /api/v1/check. Milliseconds, before any GPU is billed.
info
pattern
R25
| Trigger | More than one positional-encoding layer (positionalEncoding, learnedPositionalEmbedding, rope, alibi) in the model. |
|---|---|
| Why | Position is normally injected once. Stacking absolute + rotary, or two of the same, double-counts position and tends to hurt more than help. |
| Source | Positional-encoding design: Vaswani et al. 2017, RoPE (Su et al. 2021). |
Why it is not a lint you can ignore
A structural mistake does not fail at review time and it does not fail at import
time. It fails when the module is constructed on the training node, after the job was queued and
the dataset was downloaded. That is why this runs before the spend and not after it.
