Learning Facts at Scale with Active Reading

A visual map of a training curriculum that tries to turn bounded documents into closed-book factual memory, plus the places where the paper still needs cleaner evidence.

Episode-reported move from raw-document fine-tuning to Active Reading on the linked SimpleQA-style Wikipedia setup.

Finance Relative Lift
+160%

A stronger relative gain than the Wikipedia slice, but still far from gold-context behavior and still sensitive to abstention quality.

Scaling Signal
1T synthetic tokens

The big story is not a new transformer block. It is a much bigger and more pedagogical continued-pretraining diet.

Study Engine

Active Reading reframes the document as something to study, not merely reread. Click through the stages to see how the paper turns source pages into tailored training artifacts.

Transform Inventory

Paraphrase breaks dependence on original sentence order.
Active recall forces the answer to be produced from memory.
Timeline / association reshapes entity facts into linked structures.
Analogy / comparison increases retrieval routes inside the weights.

What Is New Here

This is mainly a curriculum paper. The model studies synthetic materials designed to teach the document, instead of only seeing the document again or getting a narrow stream of QA pairs.

Retention Grid

This heatmap is illustrative mock data shaped to match the episode’s ranking of methods: raw rereading helps least, synthetic QA helps more, and the broader Active Reading mix holds up better across rephrasings.

blue → orange → red = stronger retention

Rows

The row axis stresses the same fact under different question styles: exact recall, paraphrase, temporal phrasing, association, distractor pressure, and number-heavy asks.

Columns

The column axis spreads fact types across entity, date, causal, alias, numeric, and relation-heavy pockets to mimic a bounded document archive.

Method Colors

Raw FT sees the original documents again.
Paraphrase adds rewordings but stays narrow.
Synthetic QA teaches explicit question-answer mappings.
Active Reading mixes study formats and keeps improving longer.

Reading Caution

The strongest chart is also the messiest attribution story. Equal-compute controls are missing, so data mix, steps, and total budget all move at once.

Deployment Lens

The paper matters most where documents are stable and low-latency closed-book answers matter. The scenario toggle shifts the recommended zone and shows why retrieval still dominates freshness-critical settings.

Big Missing Controls

The episode repeatedly flags equal-compute baselines, held-out documents, and broader paraphrase transfer as the experiments most needed next.

Why Teams Still Use Retrieval

Retrieval keeps provenance, freshness, revocation, and citations in the loop. Parametric memory wins on latency and packaging, but it is harder to edit cleanly.
