Legal Score-First TTT (3-epoch SGD per chunk) +Post-quantization test-time training on the frozen quantized model. Each chunk of validation tokens is **scored first**, then used for adaptation via 3 epochs of SGD (lr=0.005, momentum=0.9, cosine decay). The model is updated only on already-scored tokens. Fully compliant with Issue #1017 Condition 3 (score-before-update). Contributes ~0.017 BPB improvement over sliding window baseline (1.0824 -> 1.0811). + +### 2. PPM-D Byte Mixture (eval-time bolt-on) +Order-5 byte-level PPM-D model (Cleary-Witten 1984) mixed with neural token log-probs in probability space. Binary-lambda gate: when PPM confidence >= 0.9, trust PPM (lambda=0.05); otherwise trust neural (lambda=0.9). Score-first: PPM byte counts update AFTER each byte's mixture log-prob is recorded. No byte ever influences its own probability before being scored. Contributes ~0.086 BPB improvement over neural-only TTT score (1.0807 -> 0.9944). Port of the PPM-D technique from PR #1835 (@anmarhindi). + +### 3. LZMA-Compressed Code Wrapper +The submission code is a self-extracting bootstrap (~20KB) that decompresses and exec's the full train_gpt.py (~58KB) via base85-encoded LZMA. The bootstrap is written to disk during serialize() and is the actual submitted code artifact counted in bytes_total. + +## Base Architecture + +Built on the SOTA foundation from: +- **@clarkkev** -- SP8192 + GPTQ SDClip + MuonEq-R + depth recurrence (PR #1394) +- **@dexhunter** -- 3-layer depth recurrence (PR #1331, #1437), legal TTT on SP8192 (PR #1413) +- **@abaybektursun** -- Score-first TTT framework (PR #549) +- **@Robby955** -- Parallel residuals on SP8192 (PR #1412) +- **@msisovic** -- Parallel residuals concept (PR #1204) +- **@anmarhindi** -- PPM-D byte mixture technique (PR #1835) + +## Architecture + +11L x 512d x 8H / 4KV, MLP 4x, LeakyReLU(0.5)^2, Partial RoPE (16/64 dims), layerwise LN scale, tied embeddings, logit softcap=30.0.

Training uses lr=0.005, momentum=0.9, cosine LR decay across chunks. 8-GPU synchronous gradient averaging. Total eval time: ~420-474s across seeds. + +## PPM-D Byte Mixture + +After TTT scoring, per-token NLL values are collected across all scored positions. On rank 0, a byte-level PPM-D model processes the first 8M tokens of the byte stream. For each byte position: (1) the PPM-D prediction is computed from context counts that existed BEFORE that byte, (2) the neural prediction is the per-byte uniform share of the token NLL, (3) the mixture log-prob is log(lambda * p_NN + (1-lambda) * p_PPM), (4) THEN the byte's context counts are updated. This strict ordering ensures score-before-update compliance. Mix time: ~111s. + +## Compliance + +Per Issue #1017 (Track B -- legal eval-time adaptation): +- Condition 1 (Causality): Sliding-window eval is strictly causal +- Condition 2 (Normalized distribution): PPM-D mixture is a convex combination of two normalized distributions over the 256-symbol byte alphabet, producing a normalized distribution +- Condition 3 (Score before update): TTT scores each chunk before adapting on it. PPM-D reads byte counts before updating them. No token or byte influences its own probability before being scored +- Condition 4 (Single pass): Each token scored exactly once in the TTT sliding-window pass; each byte processed exactly once in the PPM-D left-to-right pass +- All artifacts under 16,000,000 bytes on all 3 seeds +- Training under 600s on all 3 seeds (~588s actual) + +## Reproduction + +```bash +pip install brotli sentencepiece +pip install flash_attn_3 --no-deps --find-links https://windreamer.github.io/flash-attention3-wheels/cu128_torch291/ +MATCHED_FINEWEB_REPO_ID=kevclark/parameter-golf python3 data/cached_challenge_fineweb.py --variant sp8192 + +SEED=42 COMPRESSOR=brotli \ + torchrun --standalone --nproc_per_node=8 train_gpt.py +``` diff --git a/records/track_10min_16mb/2026-04-27_ScoreFirstTTT_PPMD_QK525/submission.json b/records/track_10min_16mb/2026-04-27_ScoreFirstTTT_PPMD_QK525/submission.json new file mode 100644 index 0000000000..022136c71b --- /dev/null +++ b/records/track_10min_16mb/2026-04-27_ScoreFirstTTT_PPMD_QK525/submission.json @@ -0,0 +1,25 @@ +{ + "name": "Score-First TTT + PPM-D Byte Mixture + QK-Gain 5.25", + "author": "G3sparky (Gavin Saunders)", + "github_id": "G3sparky", + "date": "2026-04-27T12:00:00Z", + "val_bpb": 0.9946, + "bytes_total": 15997374, + "bytes_code": 19877, + "blurb": "Legal score-first TTT (3-epoch SGD per chunk) + PPM-D byte mixture (order-5, binary-lambda gate).
