Pool tokenized: 199.9M tokens / 182,016 docs. Now the curation script — DSIR-style importance resampling against the 3 target registers, plus quality filters and dedup.

{
  "file_path": "/workspace/curate.py",
  "content": "\"\"\"Curate /workspace/data/pool.jsonl into a priority-ordered selection.json.\n\nCRITERION (stated, reproducible, no hand-picked ids)\n====================================================\nThe disclosed evaluation target is a BROAD mixture of high-quality English:\nencyclopedic (Wikipedia), general high-quality web prose, news, and technical Q&A.\nWe therefore select documents by *domain-matched importance weighting under a\nquality floor*, with an explicit mixture quota so that the 12M-token prefix of the\nselection reproduces the target's register mixture:\n\n  1. QUALITY FLOOR (hard filters, Gopher/C4-style).  Drop documents that no\n     high-quality English corpus would contain: too short, degenerate word\n     lengths, low English function-word density, heavy non-ASCII, heavy line\n     duplication, SHOUTING, or nav/boilerplate symbol soup.\n  2. DEDUPLICATION.  MinHash banding on 5-word shingles; keep the first\n     occurrence of each near-duplicate cluster.  Duplicated tokens waste budget.\n  3. IMPORTANCE WEIGHTS (DSIR).  We fit hashed unigram+bigram bag-of-words\n     distributions for (a) each register of the *target* (read off the disclosed\n     dev target, segmented at <|endoftext|> and register-classified by surface\n     form) and (b) the *pool* itself as background.  Each pool document is scored\n     by its length-normalised log importance ratio\n         s_r(d) = (1/|d|) * sum_{w in d} log( p_r(w) / p_pool(w) )\n     for each register r.  This is high for documents whose *content and surface\n     form* are distributed like that register and low for generic web filler.\n  4. MIXTURE QUOTA + INTERLEAVE.  Fill a token quota per register from that\n     register's ranking, then interleave the three ranked streams in proportion\n     to their quotas, so any truncation of the list (in particular at 12M tokens)\n     still holds the target mixture.\n\nSurface-form markers (HTML tags, code fences, headings) are kept as pseudo-words\nso that the technical-Q&A register matches on markup as well as on vocabulary.\n\nOutputs /workspace/submission/selection.json (priority order, best first).\n\"\"\"\nimport argparse, hashlib, json, os, re, sys\nimport numpy as np\nfrom multiprocessing import Pool\n\nPOOL = \"/workspace/data/pool.jsonl\"\nDEV = \"/workspace/data/multi_dev.npy\"\nCACHE = \"/workspace/cache\"          # doc_lens.npy from tok_pool.py (exact GPT-2 token counts)\nFEAT = \"/dev/shm/feat\"\nNBUCKET = 1 << 18\nCHUNK = 2000\nBUDGET = 12_000_000\n# token-share quota per register in the 12M prefix.

QUALITY FLOOR (hard filters, Gopher/C4-style).  Drop documents that no\n     high-quality English corpus would contain: too short, degenerate word\n     lengths, low English function-word density, heavy non-ASCII, heavy line\n     duplication, SHOUTING, or nav/boilerplate symbol soup.\n  2. DEDUPLICATION.  MinHash banding on 5-word shingles; keep the first\n     occurrence of each near-duplicate cluster.  Duplicated tokens waste budget.\n  3. IMPORTANCE WEIGHTS (DSIR).  We fit hashed unigram+bigram bag-of-words\n     distributions for (a) each register of the *target* (read off the disclosed\n     dev target, segmented at <|endoftext|> and register-classified by surface\n     form) and (b) the *pool* itself as background.  Each pool document is scored\n     by its length-normalised log importance ratio\n         s_r(d) = (1/|d|) * sum_{w in d} log( p_r(w) / p_pool(w) )\n     for each register r.  This is high for documents whose *content and surface\n     form* are distributed like that register and low for generic web filler.\n  4. MIXTURE QUOTA + INTERLEAVE.  Fill a token quota per register from that\n     register's ranking, then interleave the three ranked streams in proportion\n     to their quotas, so any truncation of the list (in particular at 12M tokens)\n     still holds the target mixture.\n\nSurface-form markers (HTML tags, code fences, headings) are kept as pseudo-words\nso that the technical-Q&A register matches on markup as well as on vocabulary.\n\nOutputs /workspace/submission/selection.json (priority order, best first).\n\"\"\"\nimport argparse, hashlib, json, os, re, sys\nimport numpy as np\nfrom multiprocessing import Pool\n\nPOOL = \"/workspace/data/pool.jsonl\"\nDEV = \"/workspace/data/multi_dev.npy\"\nCACHE = \"/workspace/cache\"          # doc_lens.npy from tok_pool.py (exact GPT-2 token counts)\nFEAT = \"/dev/shm/feat\"\nNBUCKET = 1 << 18\nCHUNK = 2000\nBUDGET = 12_000_000\n# token-share quota per register in the 12M prefix.

random (do-nothing)485.5
global DSIR, no mixture control411.9
mixture DSIR, no quality floor355.0
full pipeline (main)333.9

Mixture control is the dominant lever. Let me add finer-grained target modeling and tuning knobs, then run a second round of ablations.
