# EDB-Bio

EDB-Bio is the evidence-deliberation benchmark from **"Do Language Models Know What Compelling Scientific
Evidence Looks Like?"** ([arXiv](ARXIV_URL), [code](https://github.com/EdisonScientific/ibis0)).

Each episode pairs a biological **hypothesis** with a pool of **evidence stubs**: real measurements from the
same public resource, each shown with its scientific context. The model must report the probability that a
held-out measurement supports the hypothesis. The held-out measurement never appears in its own evidence pool,
and the amount, relevance and strength of the evidence are controlled during construction. Labels come from
the held-out measurement.

| Config | Source | Hypothesis | Label is 1 when the held-out measurement shows |
|---|---|---|---|
| `tahoe` | Tahoe-100M | drug *D* up/down-regulates gene *G* in cell line *C* | DESeq2 padj < 0.05, \|log2FC\| > 0.5, matching direction |
| `depmap` | DepMap 24Q4 + PRISM 24Q2 | gene *G* is a dependency in cell line *C* | Chronos gene effect ≤ −0.5 and dependency probability ≥ 0.5 |
| `gwas` | NHGRI-EBI GWAS Catalog | SNP *S* (risk allele *A*) influences trait *T* in a stated direction | p < 5×10⁻⁸ with matching effect direction |

## Configs

Nine configs in three families. The domain configs hold the episodes; the two testset families are
**frozen evaluation instances** cut from them, so that scores are comparable across runs and papers.

| family | config | train | validation | test | what it is |
|---|---|---|---|---|---|
| domain | `gwas` | 29,744 | 256 | 2,000 | the episodes, each with its **complete** 16-stub `context_pool` |
| domain | `depmap` | 29,741 | 256 | 2,000 | " |
| domain | `tahoe` | 29,741 | 256 | 2,000 | " |
| primary | `testset-primary-{gwas,depmap,tahoe}` | — | — | 2,000 | the same 2,000 test episodes, each cut to **one** sampled `k` (2–16, seed 0) |
| sensitivity | `testset-sensitivity-{gwas,depmap,tahoe}` | — | — | 4,352 | **256** episodes, each repeated **17 times**, at `k` = 0,1,2,…,16 |

Why the testsets exist: how much evidence a model sees drives its score, so an evaluation that
re-samples `k` is not reproducible. The testsets freeze that choice. `testsets/provenance.json`
records the builder, seed, revision and `k` ranges.

**The pools are physically truncated — no special loader is needed.** In both testset families
`len(context_pool) == k` for every row (verified: 2000/2000 and 4352/4352). To run an evidence
sweep, load the sensitivity config and group by `episode_id`; the 17 rows are the 17 values of `k`.

```python
from datasets import load_dataset
ds = load_dataset("EdisonScientific/EDB-Bio", "testset-sensitivity-gwas", revision="v1.0.0")
# 4,352 rows = 256 episodes x k in 0..16; one row per (episode, k)
```

## Splits

| Config | train | validation | test | Evidence pool per episode |
|---|---:|---:|---:|---|
| `gwas` | 29,744 | 256 | 2,000 | 16 stubs |
| `depmap` | 29,741 | 256 | 2,000 | 15–16 stubs |
| `tahoe` | 29,741 | 256 | 2,000 | up to 32 stubs |

Labels are balanced (50% positive). Each episode's `context_pool` is pre-shuffled; rendering its first *k*
stubs gives nested contexts. The paper trains with *k* drawn uniformly from 2–16.

## Evaluation sets

The paper evaluates on two fixed sets per domain, drawn from the test split, in `testsets/`. One row is one
model call: `context_pool` is already cut to that row's context length `k`.

| Config | Rows per domain | Episodes | Use |
|---|---:|---:|---|
| `testset-primary-<domain>` | 2,000 | 2,000 | Headline metrics. Each episode at one `k`, balanced over 2–16. |
| `testset-sensitivity-<domain>` | 4,352 | 256 | Evidence-sensitivity analyses. Each episode at every `k` = 0…16. |

Added columns: `domain`, `testset`, `k` (requested length) and `n_stubs` (actual stub count). The sets are
built by `scripts/analysis/multidomain/build_static_testset.py` at default arguments; a rebuild from this
revision is byte-identical. `testsets/provenance.json` records the arguments and row counts.

## Schema

Shared by all three domains:

| column | type | description |
|---|---|---|
| `episode_id` | string | stable identifier; the join key across configs |
| `label` | int | the answer key: 1 if the held-out measurement supports the claim, else 0 |
| `context_pool` | list | the evidence stubs revealed to the model, oldest first |
| `target_gene` | string | gene the episode is about |
| `target_gene_meta` | struct | annotations for that gene |
| `target_direction` | string | direction of the claimed effect |
| `negative_type` | string | null for positives; for negatives, why the claim fails (see below) |
| `sufficiency_tier` | string | `rich` / `moderate` / `poor` — how much *supporting* evidence the pool was built to contain (see below) |

Testset configs add `domain`, `testset`, `k`, `n_stubs` (`k` == `n_stubs` == `len(context_pool)`).

Domain-specific:

| domain | columns |
|---|---|
| `gwas` | `target_snp`, `target_snp_meta`, `target_trait`, `target_trait_meta`, `target_allele`, `target_efo_parent`, `ood_group`, `ground_truth` |
| `depmap` | `target_cell`, `target_cell_id`, `target_cell_meta`, `lineage`, `ood_group`, `ground_truth` |
| `tahoe` | `target_drug`, `target_drug_meta`, `target_cell`, `target_cell_meta`, `lineage`, `lfc_threshold`, `ground_truth_de` |

`ground_truth` / `ground_truth_de` hold the held-out measurement that `label` is derived from. They
are **not** shown to a model being evaluated; they are published so the label can be audited.

**Columns provided for downstream analysis, not used by the paper's models.** `negative_type`,
`sufficiency_tier` and `target_efo_parent` are episode strata: the reward environments and the
evaluation code do not read them (only the test suite does).

### `sufficiency_tier`
A **designed** variable, not a measured one (principle P4, Appendix A of the paper). Each episode
is assigned a stratum by quota *before* its pool is built; the pool is then filled with exactly
that many supporting relevant stubs and capped there, the rest of the budget going to
non-supporting relevant stubs. A `poor` pool therefore contains **zero** supporting stubs by
construction. Episodes are split in roughly equal thirds. What counts as "supporting" is
domain-specific:
| domain | what the tier counts |
|---|---|
| `tahoe` | conclusive (significant) related stubs: `rich` ≥ 4, `moderate` 1–3, `poor` none. Rich pools average 5.7 conclusive stubs against 0.8 for poor; 88% of all stubs are inconclusive |
| `depmap` | evidence *supporting* a dependency — related cell lines that are themselves dependencies, over-expression, amplification, damaging mutation, drug sensitivity |
| `gwas` | genome-wide-significant related stubs, by capping. Because the catalog holds only significant hits, non-significant *related* evidence is scarce, so `poor` pools fill largely with unrelated controls |
**Not to be confused with the paper's "relevance tier".** That is a different axis — the expert
hierarchy of how *directly* a stub bears on the target — and it is the one the belief-revision
results are reported against.
### `negative_type`

Null for every positive episode. For negatives it records which test the held-out measurement
failed, and the categories are domain-specific:

| domain | values | meaning |
|---|---|---|
| `gwas` | `sub_threshold` | held-out association did not reach genome-wide significance |
| | `direction_inconsistent` | significant, but the effect allele or direction disagrees with the context |
| `depmap`, `tahoe` | `inconclusive` | the measurement does not settle the claim |
| | `refuted` | the measurement contradicts it |

## Use

```python
from datasets import load_dataset
ds = load_dataset("EdisonScientific/EDB-Bio", "tahoe", revision="v1.0.0")
test = load_dataset("EdisonScientific/EDB-Bio", "testset-primary-tahoe", revision="v1.0.0")
```

The reward environments in the code repository render episodes into prompts exactly as in the paper
(`envs/{gwas,depmap,tahoe}_meta`).

## Construction

Each domain is built by one seeded script in the code repository
(`scripts/data_pipeline/build_{gwas,depmap,tahoe_meta}_dataset.py`). Every build writes `manifest.json`
recording its parameters and summary statistics. The published files are the canonical version: the GWAS
Catalog is updated weekly, so rebuilding `gwas` from a later download gives a different set of associations. Appendix A of the paper describes the construction, the
evidence-relevance hierarchy of each domain, and the design principles.

**Known limitation.** Splits are assigned i.i.d., so one episode's held-out measurement can appear as an
evidence stub in another episode on the other side of the split. This affects 0.6% (Tahoe), 10.1% (DepMap) and
53.2% (GWAS) of test episodes. The paper measures the effect on reported metrics, which is small (at most 0.005
macro Brier for the trained models).

	# EDB-Bio

	EDB-Bio is the evidence-deliberation benchmark from **"Do Language Models Know What Compelling Scientific
	Evidence Looks Like?"** ([arXiv](ARXIV_URL), [code](https://github.com/EdisonScientific/ibis0)).

	Each episode pairs a biological hypothesis with a pool of evidence stubs: real measurements from the
	same public resource, each shown with its scientific context. The model must report the probability that a
	held-out measurement supports the hypothesis. The held-out measurement never appears in its own evidence pool,
	and the amount, relevance and strength of the evidence are controlled during construction. Labels come from
	the held-out measurement.

	\| Config \| Source \| Hypothesis \| Label is 1 when the held-out measurement shows \|
	\|---\|---\|---\|---\|
	\| `tahoe` \| Tahoe-100M \| drug D up/down-regulates gene G in cell line C \| DESeq2 padj < 0.05, \\|log2FC\\| > 0.5, matching direction \|
	\| `depmap` \| DepMap 24Q4 + PRISM 24Q2 \| gene G is a dependency in cell line C \| Chronos gene effect ≤ −0.5 and dependency probability ≥ 0.5 \|
	\| `gwas` \| NHGRI-EBI GWAS Catalog \| SNP S (risk allele A) influences trait T in a stated direction \| p < 5×10⁻⁸ with matching effect direction \|

	## Configs

	Nine configs in three families. The domain configs hold the episodes; the two testset families are
	frozen evaluation instances cut from them, so that scores are comparable across runs and papers.

	\| family \| config \| train \| validation \| test \| what it is \|
	\|---\|---\|---\|---\|---\|---\|
	\| domain \| `gwas` \| 29,744 \| 256 \| 2,000 \| the episodes, each with its complete 16-stub `context_pool` \|
	\| domain \| `depmap` \| 29,741 \| 256 \| 2,000 \| " \|
	\| domain \| `tahoe` \| 29,741 \| 256 \| 2,000 \| " \|
	\| primary \| `testset-primary-{gwas,depmap,tahoe}` \| — \| — \| 2,000 \| the same 2,000 test episodes, each cut to one sampled `k` (2–16, seed 0) \|
	\| sensitivity \| `testset-sensitivity-{gwas,depmap,tahoe}` \| — \| — \| 4,352 \| 256 episodes, each repeated 17 times, at `k` = 0,1,2,…,16 \|

	Why the testsets exist: how much evidence a model sees drives its score, so an evaluation that
	re-samples `k` is not reproducible. The testsets freeze that choice. `testsets/provenance.json`
	records the builder, seed, revision and `k` ranges.

	The pools are physically truncated — no special loader is needed. In both testset families
	`len(context_pool) == k` for every row (verified: 2000/2000 and 4352/4352). To run an evidence
	sweep, load the sensitivity config and group by `episode_id`; the 17 rows are the 17 values of `k`.

	```python
	from datasets import load_dataset
	ds = load_dataset("EdisonScientific/EDB-Bio", "testset-sensitivity-gwas", revision="v1.0.0")
	# 4,352 rows = 256 episodes x k in 0..16; one row per (episode, k)
	```

	## Splits

	\| Config \| train \| validation \| test \| Evidence pool per episode \|
	\|---\|---:\|---:\|---:\|---\|
	\| `gwas` \| 29,744 \| 256 \| 2,000 \| 16 stubs \|
	\| `depmap` \| 29,741 \| 256 \| 2,000 \| 15–16 stubs \|
	\| `tahoe` \| 29,741 \| 256 \| 2,000 \| up to 32 stubs \|

	Labels are balanced (50% positive). Each episode's `context_pool` is pre-shuffled; rendering its first k
	stubs gives nested contexts. The paper trains with k drawn uniformly from 2–16.

	## Evaluation sets

	The paper evaluates on two fixed sets per domain, drawn from the test split, in `testsets/`. One row is one
	model call: `context_pool` is already cut to that row's context length `k`.

	\| Config \| Rows per domain \| Episodes \| Use \|
	\|---\|---:\|---:\|---\|
	\| `testset-primary-<domain>` \| 2,000 \| 2,000 \| Headline metrics. Each episode at one `k`, balanced over 2–16. \|
	\| `testset-sensitivity-<domain>` \| 4,352 \| 256 \| Evidence-sensitivity analyses. Each episode at every `k` = 0…16. \|

	Added columns: `domain`, `testset`, `k` (requested length) and `n_stubs` (actual stub count). The sets are
	built by `scripts/analysis/multidomain/build_static_testset.py` at default arguments; a rebuild from this
	revision is byte-identical. `testsets/provenance.json` records the arguments and row counts.

	## Schema

	Shared by all three domains:

	\| column \| type \| description \|
	\|---\|---\|---\|
	\| `episode_id` \| string \| stable identifier; the join key across configs \|
	\| `label` \| int \| the answer key: 1 if the held-out measurement supports the claim, else 0 \|
	\| `context_pool` \| list \| the evidence stubs revealed to the model, oldest first \|
	\| `target_gene` \| string \| gene the episode is about \|
	\| `target_gene_meta` \| struct \| annotations for that gene \|
	\| `target_direction` \| string \| direction of the claimed effect \|
	\| `negative_type` \| string \| null for positives; for negatives, why the claim fails (see below) \|
	\| `sufficiency_tier` \| string \| `rich` / `moderate` / `poor` — how much supporting evidence the pool was built to contain (see below) \|

	Testset configs add `domain`, `testset`, `k`, `n_stubs` (`k` == `n_stubs` == `len(context_pool)`).

	Domain-specific:

	\| domain \| columns \|
	\|---\|---\|
	\| `gwas` \| `target_snp`, `target_snp_meta`, `target_trait`, `target_trait_meta`, `target_allele`, `target_efo_parent`, `ood_group`, `ground_truth` \|
	\| `depmap` \| `target_cell`, `target_cell_id`, `target_cell_meta`, `lineage`, `ood_group`, `ground_truth` \|
	\| `tahoe` \| `target_drug`, `target_drug_meta`, `target_cell`, `target_cell_meta`, `lineage`, `lfc_threshold`, `ground_truth_de` \|

	`ground_truth` / `ground_truth_de` hold the held-out measurement that `label` is derived from. They
	are not shown to a model being evaluated; they are published so the label can be audited.

	Columns provided for downstream analysis, not used by the paper's models. `negative_type`,
	`sufficiency_tier` and `target_efo_parent` are episode strata: the reward environments and the
	evaluation code do not read them (only the test suite does).

	### `sufficiency_tier`

	A designed variable, not a measured one (principle P4, Appendix A of the paper). Each episode
	is assigned a stratum by quota before its pool is built; the pool is then filled with exactly
	that many supporting relevant stubs and capped there, the rest of the budget going to
	non-supporting relevant stubs. A `poor` pool therefore contains zero supporting stubs by
	construction. Episodes are split in roughly equal thirds. What counts as "supporting" is
	domain-specific:

	\| domain \| what the tier counts \|
	\|---\|---\|
	\| `tahoe` \| conclusive (significant) related stubs: `rich` ≥ 4, `moderate` 1–3, `poor` none. Rich pools average 5.7 conclusive stubs against 0.8 for poor; 88% of all stubs are inconclusive \|
	\| `depmap` \| evidence supporting a dependency — related cell lines that are themselves dependencies, over-expression, amplification, damaging mutation, drug sensitivity \|
	\| `gwas` \| genome-wide-significant related stubs, by capping. Because the catalog holds only significant hits, non-significant related evidence is scarce, so `poor` pools fill largely with unrelated controls \|

	Not to be confused with the paper's "relevance tier". That is a different axis — the expert
	hierarchy of how directly a stub bears on the target — and it is the one the belief-revision
	results are reported against.

	### `negative_type`

	Null for every positive episode. For negatives it records which test the held-out measurement
	failed, and the categories are domain-specific:

	\| domain \| values \| meaning \|
	\|---\|---\|---\|
	\| `gwas` \| `sub_threshold` \| held-out association did not reach genome-wide significance \|
	\| \| `direction_inconsistent` \| significant, but the effect allele or direction disagrees with the context \|
	\| `depmap`, `tahoe` \| `inconclusive` \| the measurement does not settle the claim \|
	\| \| `refuted` \| the measurement contradicts it \|

	## Use

	```python
	from datasets import load_dataset

	ds = load_dataset("EdisonScientific/EDB-Bio", "tahoe", revision="v1.0.0")
	test = load_dataset("EdisonScientific/EDB-Bio", "testset-primary-tahoe", revision="v1.0.0")
	```

	The reward environments in the code repository render episodes into prompts exactly as in the paper
	(`envs/{gwas,depmap,tahoe}_meta`).

	## Construction

	Each domain is built by one seeded script in the code repository
	(`scripts/data_pipeline/build_{gwas,depmap,tahoe_meta}_dataset.py`). Every build writes `manifest.json`
	recording its parameters and summary statistics. The published files are the canonical version: the GWAS
	Catalog is updated weekly, so rebuilding `gwas` from a later download gives a different set of associations. Appendix A of the paper describes the construction, the
	evidence-relevance hierarchy of each domain, and the design principles.

	Known limitation. Splits are assigned i.i.d., so one episode's held-out measurement can appear as an
	evidence stub in another episode on the other side of the split. This affects 0.6% (Tahoe), 10.1% (DepMap) and
	53.2% (GWAS) of test episodes. The paper measures the effect on reported metrics, which is small (at most 0.005
	macro Brier for the trained models).

	### Attribution required by the sources

	None of the upstream providers endorses this dataset.

	GTEx. The data used to build this dataset were obtained from the GTEx Portal in July 2026 (GTEx Analysis
	Release V8, dbGaP accession phs000424.v8.p2). The Genotype-Tissue Expression (GTEx) Project was supported by the
	Common Fund of the Office of the Director of the National Institutes of Health, and by NCI, NHGRI, NHLBI, NIDA,
	NIMH, and NINDS. The GTEx-derived fields come from release V8 and do not reflect the most current data available
	from the GTEx Portal.

	GWAS Catalog. Associations are the curated top hits reported by published studies, not full summary
	statistics. Each row carries its GCST study accession; please also cite the original study where relevant.
