bnnr 0.4.6

BNNR — Train → Explain → Improve → Prove

Full demo with audio (4K): bnnr.dev

BNNR (Bulletproof Neural Network Recipe)

BNNR automatically improves your PyTorch vision models using XAI — find what your model gets wrong, fix it with intelligent augmentation, and prove the result with structured reports and a live dashboard.

Supported tasks (v0.4.6): single-label classification, multi-label classification, and object detection (COCO-mini / YOLO). See Detection docs.

Quickstart

pip install "bnnr[dashboard]"

# Zero flags — CIFAR-10 demo CNN, ICD preset, live dashboard (~1 min)
python3 -m bnnr demo

python3 -m bnnr quickstart

python3 -m bnnr train --dataset cifar10 --preset light --with-dashboard

Open http://127.0.0.1:8080/ for the live dashboard.

Already have a checkpoint? python3 -m bnnr analyze --model checkpoints/best.pt --data cifar10 --output ./analysis_out — docs.

XAI-driven augmentations (ICD & AICD)

BNNR uses saliency maps to guide augmentation — not random flips and crops.

ICD — masks the regions the model already focuses on (highest saliency), forcing it to learn from context instead of shortcuts.

AICD — masks low-saliency background and irrelevant textures, sharpening focus on discriminative features.

What makes BNNR different

• XAI-driven augmentation (ICD / AICD) — augmentations guided by saliency maps; no other PyTorch toolkit combines explainability and data augmentation this way.
• Auto-augmentation search — iterative branching keeps only augmentations that measurably improve your validation metric.
• Auditable reports — structured JSON reports with metrics, XAI heatmaps, and branch decisions for stakeholders or compliance review.
