🔬 Unlearning Configuration
- Base Model:
mistralai/Mistral-7B-v0.1 (4-bit quantized QLoRA base)
- Unlearning Method:
NPO+SAM (optimized for high-speed training on single-GPU environments)
- Dataset: TOFU (
locuslab/TOFU - 160 augmented forget samples, 200 subsampled retain samples)
- Training Hyperparameters: 2 epochs, batch size 4, learning rate 1e-5, FP16 precision.
- Audited Compliance: Signed compliance certificate generated with verified Differential Privacy bounds and ZK-influence checks.
🎯 Intended Uses & Limitations
Intended Uses
- Regulated Privacy Compliance: Erasing private user data (GDPR Art. 17 Right to Erasure, CCPA).
- Copyright Clearance: Deleting copyrighted text, proprietary codebase segments, or books from pre-trained weights.
- Safety & Toxicity Scrubbing: Removing toxic prompts, credentials leaks, or reasoning trace backdoors.
Limitations & Out-of-Scope
- Generalization: While retain set utility is preserved, aggressive unlearning of core terms might cause slight degradations in adjacent domains.
- Format: This is a PEFT Adapter. It must be loaded on top of the original
mistralai/Mistral-7B-v0.1 base model. It is not a standalone full model.
🧠 How ARMOR Works
ARMOR (Adaptive Relearning-resistant Multimodal Unlearning) addresses three fundamental vulnerabilities in classical machine unlearning:
- Relearning Recovery: Attackers can recover deleted concepts with only 5–10 gradient steps on a small subset. ARMOR blocks this by optimizing inside flat loss minima (via SAM).
- Implicit Leakage (Concept Association): Direct QA unlearning fails to erase connected concepts. ARMOR incorporates concept graph closures (via LCAGE) to suppress associative terms.
- Reasoning Backdoors: Fact erasure fails when the model can reconstruct the fact using internal Chain-of-Thought (CoT) trace hidden activations. ARMOR actively erases internal thoughts (via CoT-HME).

🛡️ Privacy & Compliance Guarantees
ARMOR integrates a complete compliance suite verifying unlearning in real-time:
- Zero-Knowledge Influence Verification: Calculates deterministic weight change commitments to prove target data was removed from base parameters without exposing the training dataset.
- Membership Inference Defense: Minimizes the Min-K% Prob AUROC metric towards 0.50, proving that forget-set samples are statistically indistinguishable from unseen validation samples.
- Differential Privacy: DP-NPO+SAM tracks formal (ϵ,δ)-Differential Privacy budgets using the Opacus privacy engine, providing mathematical guarantees against model inversion/reconstruction attacks.
