Ailiance — Apertus-70B-Instruct emc-dsp-power LoRA

LoRA adapter fine-tuned on swiss-ai/Apertus-70B-Instruct-2509 for emc-dsp-power tasks.

Maintained by Ailiance — French AI org publishing EU AI Act aligned LoRA adapters and datasets.

✅ Training data attribution audited (2026-05-11)

Trained on Ailiance-fr/mascarade-emc-dataset (4.05% SE), Ailiance-fr/mascarade-dsp-dataset (5.35% SE), Ailiance-fr/mascarade-power-dataset (4.87% SE). Per-sample Stack Exchange Electronics attribution recovered via SE API search: only ~4.05–5.35 % of samples per dataset are from Stack Exchange Electronics (now fully attributed in metadata.stack_exchange_attribution — URL + author + post_id + creation_date).

Original heuristic estimate of "~30 % SE" was over-counted by ~6–7× (style ≠ source). See audit trail for the methodology (/search/advanced + body match ≥ 0.60).

Remaining content is either (a) style-resembling SE but not findable on the API (marked attribution_recovery=not_found_on_se, probable synthetic) or (b) synthetic LLM-generated.

Quick start (MLX)

from mlx_lm import load, generate

model, tokenizer = load(
    "swiss-ai/Apertus-70B-Instruct-2509",
    adapter_path="Ailiance-fr/apertus-emc-dsp-power-lora",
)

print(generate(model, tokenizer, prompt="..."))

Benchmark roadmap

This LoRA has not yet been evaluated through electron-bench (the current pipeline supports gemma-4-E4B base only). Training was completed with the standard mlx-lm LoRA trainer (rank 16, alpha 32, scale 2.0, AdamW LR 1e-5, 500 iters) — full hyperparameters are in the Training table above.

Planned evaluations:

• Perplexity on the validation split of the training data
• Functional benchmark on apertus-specific tasks
• Comparison vs base swiss-ai/Apertus-70B-Instruct-2509

Track progress: ailiance-bench issues.

For reference benchmarks on the gemma-4-E4B base, see the base-vs-LoRA matrix.
