SNN-4-ALL MICRO 2026 AE Checkpoints

This repository contains checksum-verified checkpoints prepared for the MICRO 2026 Artifact Evaluation package of:

SNN-4-All: Breaking the Edge Fine-Tuning Barrier with Heterogeneous Sparsity Exploitation

Source artifact

• GitHub repository: GDHNES/SNN-4-ALL-AE-release
• Planned evaluated release: micro2026-ae-v1.1
• The exact evaluated source commit is recorded by the tagged GitHub release and the corresponding archival record.

Included checkpoints

• Server SpikingVGG-11 baseline, coupled-protocol epoch 30
• Server SpikingVGG-11 TwiST (0.7-2), coupled-protocol epoch 24
• Orin Spikformer baseline historical best checkpoint
• Orin Spikformer TwiST historical best checkpoint

The Server SpikingVGG-11 baseline and TwiST checkpoints were produced by full training under the recovered coupled historical protocol. Their independently evaluated accuracies were 58.1% and 59.5%, versus 59.4% and 60.2% reported in the paper; both satisfy the pre-declared +/-3 percentage-point tolerance.

The Orin Spikformer checkpoints support checksum-verified, complete-test and resource replay. This is checkpoint-based replay evidence, not a new full-training reproduction.

Integrity and license

Verify every checkpoint against CHECKSUMS.sha256 before use. Exact provenance and the redistribution license are documented in CHECKPOINT_LICENSES.md and checkpoint_manifest.json.

The public SpikeGPT-216M checkpoint is not duplicated here. The source artifact downloads the upstream Apache-2.0 checkpoint directly from the immutable revision recorded in its downloader and verifies its SHA-256.

Public validation

An anonymous, token-free download from an empty cache was completed against a full immutable Hugging Face revision. All four SHA-256 checks passed. The four downloaded checkpoints then reproduced the expected complete-test accuracies: 58.1% and 59.5% for Server SpikingVGG-11 baseline/TwiST, and 75.9% and 75.7% for Orin Spikformer baseline/TwiST.
