Cyclic Calendar Story Reasoning v2
v2 of liodon-ai/math-dow-mod-synthetic-v1, rebuilt around one piece of feedback from running v1 at scale: story and reasoning diversity has to scale to millions of rows, or it reads as one template repeated. v1's story setups were picked off a fixed list of 8 full sentences per task/direction, and every reasoning trace followed one fixed 4-slot skeleton (opener / op / mod-reduce / conclude) with only the wording swapped — fine at 10-50k rows, but at millions of rows the shape of every derivation is identical even though the words differ.
Scope change from v1
Per request, this file is scoped to the four cyclic families only —
days_of_week, months, hour_12, hour_24. Addition/multiplication/mod
probes are dropped (being generated separately as plain a + b problems);
this generator is only about "very creative days problems, and hours,
months." Base 10 only — translate to base 6/7 the same way v1's base-10
distribution was meant to be translated.
What actually changed vs. v1
- Stories are Mad-Libs, not a fixed sentence list. Setup sentences are composed from three independent pools — 60 subjects (roles: "a lighthouse keeper", "the glacier researcher", ...) × 60 locations ("a converted grain silo", "a rooftop apiary", ...) × 8 sentence frames — giving 28,800 setup combinations per task/direction instead of 8. Tail questions expanded from 4 to 10 phrasings per direction.
- Four structurally different reasoning derivations, not four
rewordings of one skeleton:
positional_mod— v1's position → op → mod-reduce → conclude skeleton (kept, since it's the clearest single derivation), but the mod-reduce step now only claims "wraps around" when a wrap actually happened — v1 said "3 wraps around (mod 7) to 3" even when nothing wrapped.wraparound— explicitly separates whole cycles from the remainder for offsets ≥ the cycle length ("25 days is 3 full cycles of 7 plus 4 left over..."), and a short direct sentence when no wrap occurs.step_walk— enumerates the cycle one unit at a time for small offsets ("Stepping forward 4 hours from 23: 0, 1, 2, then 3.") — the one style closest to how a person actually counts small offsets.concise— a single terse notation line ((3 + 21) mod 7 = 3 = Thursday.), the minority style so the model also sees direct-notation derivations, not only prose ones. Trace length and structure now genuinely varies, not just word choice.
- Offsets shifted smaller: mostly 1-10 (75% of the time) with a thin tail to 25 (was mostly 1-12, tail to 20) — "up to 25 or even 20... mostly smaller numbers."
- Bare/plain question phrasing expanded 3 → 10 per direction, since at
the repeat counts needed for millions of rows (hundreds to ~2,000
paraphrases per underlying fact — the math domain is inherently only
~350-1,200 unique
(start, offset, direction)facts per family at these offset ranges) a 3-line pool collides by pigeonhole long before a 60×60×8 story pool does.
Honesty about the duplicate rate
The underlying math domain is small by construction (small cyclic moduli,
small offset range, per Alper's "mostly smaller numbers" request) — millions
of rows necessarily means hundreds to ~2,000 paraphrases of each of a few
thousand underlying facts. Exact-string duplicates were measured directly
(not estimated) by hashing every (question, answer) pair in train.jsonl:
the first widening pass took the rate from 15.17% → 7.00%, a second pass
(widening the two narrowest reasoning styles further) took it to 5.19%,
which is where this release ships. Going further ran into clearly
diminishing returns for the engineering effort — if lower is needed for a
specific training run, --repeat-cap can be lowered (fewer rows, less
reuse per fact) or the offset range widened (more underlying facts) at the
cost of shorter/more numerous reasoning traces respectively.
Generate
python3 generate_cyclic_stories_v2.py --out data_v2
Key flags: --base, --seed, --small-hi/--tail-hi/--small-frac
(offset distribution), --story-frac (story-wrapped vs. plain question
fraction, default 0.75), --repeat-cap (max paraphrases per unique fact),
--dow-n/--month-n/--hour12-n/--hour24-n and their *-ood-n
counterparts (per-family target counts) — see --help.
Splits
Same methodology as v1: test_id is a deterministic hash-based ~5-7% (by
family; see stats below) holdout of in-distribution facts (stable_bucket,
reproducible regardless of PYTHONHASHSEED); test_ood draws offsets from
a near zone (26-60) and a far zone (61-600) never seen in train, to test
extrapolation rather than memorization. Verified zero (task, start, offset, direction) fact overlap between train and either test split.
Schema
Identical to v1:
{
"messages": [
{"role": "user", "content": "A lighthouse keeper at a coastal salt farm marks Thursday as the current day. 21 days on, which day is it?"},
{"role": "assistant", "content": "Thursday corresponds to position 3 out of 7 days. Working it out: 3 + 21 = 24. 24 mod 7 = 3. So the answer is Thursday."}
],
"task": "days_of_week",
"meta": {"start": "Thursday", "offset": 21, "direction": "after", "base": 10}
}
train_raw.txt is the flattened, role-marker-free version for
pretraining-style corpora ({question} {reasoning} per line, blank-line
separated).

Verified: 0 numeric/cyclic-label mismatches across ~60,700 sampled chat
examples (2% sample across all three splits, reasoning-trace answer
re-derived independently from meta and checked against the text); 0
fact-level overlap between train and either test split; global exact
(question, answer) duplicate rate 5.19% (see "Honesty about the duplicate
rate" above).
Not yet done
- Nemotron-3 as an additional source of story/problem variety was raised as an option but not integrated here — this release is entirely self-generated (Mad-Libs composition), no external corpus mixed in.
- Base-6/base-7 versions (translate once base-10 training results are in).
- Addition/subtraction as plain
a + bproblems — out of scope for this file by request, being generated separately.
