G3-Heresy-MPOA-G-W99-D0.0199-R08

An experimental ablation of Gemma-3-27B-it, using the Heretic tool.

Compared to the standard configuration of Heretic, there are a few changes:

1. The training and test datasets used were extended compared to the default subset used by Heretic
2. A version of Magnitude-Preserving Orthogonal Ablation (MPOA) is used
3. To stay faithful to MPOA, the harmful direction to ablate is chosen from between 2 layers (Heretic's "global" direction scope)
4. To stay faithful to MPOA, a 99% winsorization is applied to the residuals
5. Some additional refusal markers were added to avoid bypassing the refusal detection with bad punctuation

To achieve strong results:

1. Parameter ranges were iteratively refined by looking at resulting refusal and divergence scores
2. The scoring function was adjusted to prioritize low-refusal results

The model name contains the properties of the ablation:

1. MPOA for the usage of Magnitude-Preserving Orthogonal Ablation
2. G for the usage of global direction scope
3. W for the usage of winsorization
4. D for the measured KL divergence
5. R for the number of refusals
