Two on-disk +schemas, both legended with a `"spatial code schema"` key that documents every field's +unit and meaning directly in the JSON: + +- **compact** — reusable geometric primitives only: per-object-instance 3D oriented + bounding boxes (center, dimensions, orientation vectors) and first-visible-time, plus + the room's floor boundary polygons. +- **explicit** — answer-oriented and *derived*: positions/dimensions/counts read + straight off compact's own boxes, a precomputed pairwise closest-class distance + table, floor area (shoelace formula on compact's polygons), and class appearance + order. Every value is a direct subset or pure function of compact's own numbers, + computed by the same shared function (`_explicit_from_compact`) regardless of + whether the compact code came from perception or ground truth — explicit and compact + can never silently disagree about the same scene's geometry, by construction, not by + convention. This is what makes H13 (below) a real, load-bearing control rather than + an assumption. + +`encoder/render.py` / `run.py` / `launch.py` build these from real SAM3 + DA3 caches. +`encoder/ground_truth.py` builds the *same* schema, legend included, directly from +`thinking-in-space`'s annotations instead — no SAM3, no DA3, no video. This is the +perfect-perception oracle: real 3D object boxes and real room area. The one thing +annotations don't carry — per-object "first visible time," a property of a specific +camera walkthrough, not of a static 3D scan — is sourced from VSI-Bench's own real +`obj_appearance_order` question answers where available (topologically merged across +every such question for a scene) and left `null`, never fabricated, where it isn't. +Rebuild with `python -m encoder.ground_truth`. + +### `symbolic/` — the formula-driven solver (no VLM) + +`symbolic/solver.py` answers every VSI-Bench question type directly from a spatial code +using closed-form geometry (parsed unit-strings, BVLS surface-distance, chained-turn +route planning) — no language model, no sampling, no learned reasoning, deterministic. +`symbolic/adapters.py` converts a compact code into the same answer-oriented shape the +explicit schema already has natively, so the solver has one internal representation +regardless of which format it reads. `symbolic/run.py` answers and scores one scene; +`symbolic/launch.py` is the multi-scene orchestrator. `symbolic/run.py:: +select_ground_truth_spatial_codes(format)` switches the solver onto ground-truth codes +instead of a perception-pipeline selection; results then land under +`results/symbolic/ground truth//` instead of the usual +`/////` chain. + +Every hypothesis tested to arrive at the current production solver/geometry (distance +formulas, box-fitting quantiles, floor-area reconstruction, room-shape recovery, etc.) +is documented with its measured before/after numbers in +`experiments/EXPERIMENT FINDINGS.md` — this is a separate, already-concluded track from +the VLM-harness hypotheses below, and its findings are already baked into +`encoder/geometric.py` and `symbolic/solver.py` as shipped. + +### `harness/A`, `B`, `C`, `D` — VLM-based answering + +All four harnesses answer the same real VSI-Bench questions with one of three VLMs +(Qwen3.5-4B, Qwen3.5-2B, InternVL3.5-4B), greedy-decoded, and write one untruncated JSON +result per question in the identical record shape (so any of them can be pointed at +`analysis.aggregate` with no per-harness special-casing). They differ only in what's +shown to the model: + +| Harness | Input | Spatial code source | +|---|---|---| +| **A** | video frames only | — | +| **B** | spatial code as text only | perceived (`encoder/`, SAM3+DA3) | +| **C** | video frames **and** spatial code, sourced from the identical `(depth, tracking, input, frames)` config so they can never mismatch | perceived (`encoder/`, SAM3+DA3) | +| **D** | spatial code as text only | **ground truth** (`encoder/ground_truth.py`) | + +Every harness's prompt (`prompts.py`) uses the same context-line → code-JSON → +question → post-prompt structure, reusing harness A's exact question-type split and +post-prompts verbatim. The context line is deliberately vague about which fields are +present — compact and explicit carry different fields (only explicit has a distance +table and appearance order; only compact has per-instance orientation vectors) — so it +never over- or under-claims either format; the code's own embedded schema legend is +what actually documents every field present in a given call. + +A uses the VSI-Bench paper's own protocol by default (greedy decoding, 16-token output +cap — the exact `lmms_eval` generation config). B, C, and D default to an *extended* +protocol instead (`answer_extended`: a large 2048-token reasoning budget, with a short +forced `"Final answer:"` continuation only if the model doesn't conclude on its own, +via literal generation continuation, not a new chat turn) — A can opt into the same via +`--extended`. Every record logs `reasoning_token_count`, `hit_token_limit`, and +`forced`, whether or not the extended protocol was used, so protocol effects can always +be measured after the fact. + +D additionally has `harness/D/symbolic_eval.py`, which runs the real symbolic solver +(no VLM at all) directly on ground-truth codes — the perfect-information ceiling, +perfect geometry *and* perfect deterministic reasoning — written through +`symbolic.run`'s own writer into `results/symbolic/ground truth//`, the same +family every other symbolic-solver result lives in, not a separate `results/D/...` +location (this IS a symbolic-solver run, just against ground-truth input instead of a +perception-pipeline selection). It therefore does not appear in +`analysis.aggregate --harness D`; use `symbolic`'s own aggregation over that results +family instead. + +Each harness has `run.py` (single-scene/single-config, importable and CLI), `launch.py` +(persistent per-GPU workers pulling scenes off a shared queue, one model load reused +across every scene a worker is assigned), and `sweep.py` (loops `launch.py` over a grid +of configs — one config fully saturating every visible GPU before the next starts). B +and C additionally sweep `depth`/`tracking` (`encoder.config`'s own vocabulary, +`metric`/`relative` and `tracking`/`no tracking`) as real, validated axes — not just +format, input-selection, and frame count — and fold them into both the results +directory nesting and each record's `"condition"` field, so two different +depth/tracking runs of the same scene/model/format can never collide on disk. + +```bash +python -m harness.A.sweep --models all --frame-selections all --frames 16,32,64 +python -m harness.B.sweep --models all --spatial-code-formats all --input-selections selective --frames 32 +python -m harness.D.sweep --models all # both spatial_code_formats always -- see "Plan D" below +python -m harness.D.symbolic_eval --spatial-code-format explicit # perfect-information ceiling +``` + +#### Results location + +| Harness | Path | +|---|---| +| A | `results/A/////.json` | +| B | `results/B////////.json` | +| C | `results/C////////.json` | +| D | `results/D////.json` (VLM path only — `symbolic_eval` writes to `results/symbolic/ground truth/...` below, not here) | +| symbolic (production) | `results/symbolic///////.json` | +| symbolic (ground truth) | `results/symbolic/ground truth///.json` | + +All overridable via env var or `--results-dir`. + +### `analysis/` — aggregation and comparison + +One shared module over every harness's results (not one per harness, since every +harness's per-question record already shares the same shape): + +- `analysis/aggregate.py` — per-category MRA/accuracy scores via the *real* official + VSI-Bench aggregator (never reimplemented, imported directly from + `thinking-in-space`), plus latency/token/forced-answer telemetry. `--harness + {A,B,C,D}` or `--results-dir`; `--csv ` to export. +- `analysis/compare.py` — joins A vs B vs C's aggregates on their shared `(model, + selection, frame_count)` dimensions into one side-by-side table (A has no + spatial_code_format axis, so its score is shown once per row against every B/C + format at that row). `--csv ` to export. + +```bash +python -m analysis.aggregate --harness B --csv b_scores.csv +python -m analysis.compare --csv comparison.csv +``` + +### `experiments/` — geometry-formula research (separate track) + +A sandboxed hypothesis-testing framework for `encoder/geometric.py`'s own math +(distance formulas, box-fitting quantiles, floor-area reconstruction, room-shape +recovery) — completely separate from the VLM-harness research below, and already +concluded: its findings are what `encoder/geometric.py` and `symbolic/solver.py` ship +with today. Full before/after numbers for every hypothesis tried: +`experiments/EXPERIMENT FINDINGS.md`.

Each is stated with the specific mechanism in this infrastructure +that makes it a *measurable* claim rather than a plausible-sounding one — a real +control, a shared record schema, an already-logged telemetry field, or a provable +derivation — not just an assertion resting on the experiment "probably" working. + +Anchor findings the hypotheses are grounded in: VSI-Bench's own manual error analysis +attributes ~71% of MLLM errors to spatial reasoning (40% relational, 31% +egocentric-allocentric transform), ~15% to perception, ~14% to language; chain-of-thought +/ self-consistency / tree-of-thought all *hurt* frames-only VSI-Bench performance (up to +-21% on size tasks); model-generated cognitive maps raised relative-distance accuracy +46→56, ground-truth maps to 66; the spatial-code paper found predicted-perception codes +score 60.0 overall vs. 73.2 with ground-truth codes on the same 4B LLM — perception, not +reasoning capacity, was their binding constraint. + +### Theme 1 — Representation substitution (A vs B) + +- **H1 — code-for-frames substitution.** B ≥ A on metric-geometry categories (absolute + distance, size, room size, relative distance). *Justified by*: A and B answer the + identical question set with the identical scorer and identical record schema, so a + category-level A-vs-B delta is a direct, paired comparison, not an approximation. +- **H2 — informed-blind baseline.** B should crush appearance order specifically (the + paper's hardest category even with RL) since the code encodes first-visible-time + explicitly. *Justified by*: `encoder`'s appearance-order field is independently + checkable against VSI-Bench's own `obj_appearance_order` ground truth, so a B failure + here is diagnosable as schema-grounding (the model not reading the legend) rather + than papered over as "information absence." +- **H3 — ego-allo split.** B improves allocentric tasks but not egocentric ones + (relative direction, route planning), since the code has no observer viewpoint. + *Justified by*: per-category breakdown is what `analysis.aggregate` already computes + from the real official scorer, so this is read directly off existing output. + +### Theme 2 — Complementarity and conflict (C vs A, B) + +- **H4 — complementarity is category-selective.** C > max(A, B) only on categories + needing both an egocentric view (frames) and exact geometry (code) — relative + direction, route planning. *Justified by*: C is built by construction from the same + `(depth, tracking, input, frames)` source as the paired B run, so a C-vs-B delta + isolates the frames' marginal contribution with no confound from a different code. +- **H5 — cross-modal interference.** For the 2B model, C < B on metric categories + (visual tokens as distractors). *Justified by*: `input_token_count` is logged on + every record, so "distraction from extra tokens" is a testable correlate, not just a + story. +- **H6 — textual anchoring under conflict.** Where the code is wrong, C follows the + code, not the frames. *Justified by*: a direct extension of harness C's own + architecture — clone its prompt-building path with one object's position/size + perturbed in the injected code, holding the real frames fixed, and check which one + the answer tracks. This is a controlled intervention this codebase can run today, not + a post-hoc correlational argument. + +### Theme 3 — Reasoning protocol (16-token vs. extended) + +- **H7 — the CoT reversal (headline hypothesis).** VSI-Bench's "CoT hurts" finding is a + representation problem, not a reasoning problem: extended reasoning hurts or is flat + for A (replicating the paper) but *helps* B and C, because reasoning over explicit + coordinates is serial symbolic computation, while reasoning over frames forces + error-amplifying visual imagination. *Justified by*: A, B, and C all support the exact + same `answer_extended` protocol (A via `--extended`, B/C by default), so the + protocol×harness interaction is measured with the *same* generation mechanism across + all three, not different ad-hoc reasoning implementations that would confound the + comparison. +- **H8 — dose-response / overthinking.** Accuracy vs. `reasoning_token_count` is + inverted-U; forced-continuation records score worst. *Justified by*: `reasoning_token_count`, + `hit_token_limit`, and `forced` are already on every extended-protocol record — zero + new runs needed, pure analysis over existing JSONs. +- **H9 — forced answers are informative.** Forced answers still beat chance on MCA + tasks. *Justified by*: same telemetry as H8, filtered to `forced == true`. +- **H10 — extended mode rescues small models on B.** The 4B–2B gap shrinks under + extended reasoning. *Justified by*: both models run the identical B pipeline at both + protocols, so the scale×protocol interaction is a clean 2×2 read off `analysis.aggregate`. + +### Theme 4 — Code format (explicit vs. compact) + +- **H11 — precomputation vs. derivation × token budget.** Explicit wins distance + categories under the 16-token protocol (answer = table lookup); compact catches up or + wins under extended reasoning. *Justified by*: both formats are answerable by every + harness with a single `--spatial-code-format` flag, at identical scenes/questions. +- **H12 — verbosity × capacity.** Compact's fuller schema helps 4B, hurts 2B. + *Justified by*: same mechanism as H11, cut by model instead of protocol. +- **H13 — schema-grounding (the cleanest control in this whole program).** Any + B(explicit) vs. B(compact) gap is *purely presentational*, because explicit is now a + provable, mechanical derivation of compact — same shared `_explicit_from_compact` + function regardless of source. *Justified by*: this isn't an assumption; it was + empirically verified (0 mismatches across every measured field: positions, + dimensions, distance table, floor area, appearance order) after fixing a real + orientation-vector renormalization bug that briefly broke the guarantee. With + information content mathematically pinned equal, any residual B(explicit)-vs-B(compact) + gap can *only* be a presentation effect — a control neither source paper could run. + +### Theme 5 — Perception inputs (frame selection and count) + +- **H14 — code as frame compression.** C at low frame counts matches A at high frame + counts. *Justified by*: `input_token_count` is logged on every record from both + harnesses, so a Pareto frontier (accuracy vs. tokens) is a direct plot, not an estimate. +- **H15 — selection matters more upstream than downstream.** The selective-vs-uniform + effect is larger on B (via encoder-side code quality) than on A (direct VLM input). + *Justified by*: A and B both expose `--frame-selections`/`--input-selections` over the + identical vocabulary (`encoder.config.INPUT_SELECTIONS`), so the same manipulation is + comparable pre- and post-encoding. Currently gated: only `selective`-mode SAM3 raw + caches exist on disk; testing this needs a `uniform`-mode encoder rebuild first. +- **H16 — frame-count saturation shifts by modality.** A saturates earlier (fewer + frames) than B's *encoder-input* frame count does. *Justified by*: `harness.A.sweep` + and `harness.B.sweep` both already support arbitrary frame-count grids; this is a + sweep-breadth question, not a new mechanism. + +### Theme 6 — Model family and scale + +- **H17 — family × modality.** InternVL3.5-4B vs. Qwen3.5-4B rank-flips between A and + B. *Justified by*: identical prompts/protocol/scorer across every model in every + harness (`harness.A.models`'s shared adapter interface) — a rank flip can't be + attributed to inconsistent handling per model. +- **H18 — scale gap is modality-dependent.** The 4B–2B gap is larger on B than A at 16 + tokens. *Justified by*: same paired-model-across-harness comparison as H17. + +### Theme 7 — Question-level error decomposition + +- **H19 — automatic perception/reasoning split.** Joining A/B/C per question + reproduces VSI-Bench's manual 71/15/14 error taxonomy automatically, at full-benchmark + scale. *Justified by*: every harness answers the identical `question_id`s from the + identical `test.jsonl`, in the identical record shape — a per-question join across + harnesses (solved-by-B-not-A, solved-by-A-not-B, solved-by-neither, solved-by-C-only) + is a plain dataframe operation over existing results, not a new experiment design. +- **H20 — cognitive-map generalization.** B's gains over A concentrate in relative + distance like the paper's cognitive-map result, and exceed its ground-truth-map + ceiling (66) because this code is 3D/metric vs. their 2D/coarse grid. *Justified by*: + directly comparable because B is evaluated by the exact same official scorer and + category breakdown the source paper itself used. + +### Plan D and the perfect-information ceiling (cross-cutting) + +Every hypothesis above that concerns *encoder* error rather than *reasoning* error (H1, +H4, H6, H7, H11, H13) gets an additional, sharper cross-check for free: D re-answers B's +same questions with a **ground-truth** spatial code instead of a perceived one, and +`harness/D/symbolic_eval.py` additionally answers them with the deterministic solver — +the perfect-geometry-and-perfect-reasoning ceiling. Any B→D gap at matched format is +attributable to perception error, not reasoning error, because nothing else changes +between the two runs (same prompt structure, same model, same questions) — this is the +concrete mechanism behind "how much of the gap is imperfect perception" in this +project's opening claim. + +--- + +## How the experiment is actually run, step by step + +Rather than a full factorial sweep across every axis, configuration is narrowed in +stages — each stage's winner freezes the next stage's config — because the model axis +is never collapsed (every stage always sweeps all 3 models) but frame count, input +selection, and spatial-code format would otherwise multiply the run count far beyond +what's needed to answer the hypotheses above. + +**Step 1 — Plan A decides frame count and input selection.** + +```bash +python -m harness.A.sweep --models all --frame-selections all --frames 16,32,64 +``` + +9 configs (3 models × {uniform, selective} × {16, 32, 64} frames), 16-token protocol. +Aggregate with `analysis.aggregate --harness A`; for each `(frame_selection, +frame_count)` cell, average the official "overall" score across all 3 models — the +argmax cell is `(selection*, frames*)`. + +*Tie-break rule*: if Plan A doesn't show a clear winner between 32 and 64 frames, +default to **32**. Both because a marginal 64-frame edge in A's own results wouldn't be +worth double the inference cost, and because the separate geometry-formula track +(`EXPERIMENT FINDINGS.md`) already found 64-frame spatial codes aren't meaningfully +better than 32-frame ones for the encoder side either — the tie-break isn't a +coin-flip, it's backed by evidence already in hand from a different part of this +project. + +**Step 2 — Regenerate spatial codes at the winning config, immediately after Step 1.** + +This has to happen right after Plan A, *before* Plan B, not later: only 72 of +VSI-Bench's 288 scenes currently have any on-disk spatial code at all (all under +`selective` input), so Plan B would be starved of scenes without this. Both formats +come from one encoder pass — since `explicit` is a pure derivation of `compact`, there +is no separate "build the losing format" step. If Plan A's winning selection turns out +to be `uniform` (not `selective`), this step is gated on building the SAM3 raw +masklet cache for uniform-mode sampling first, since that cache currently only exists +for `selective`. + +**Step 3 — Plan B decides spatial-code format.** + +```bash +python -m harness.B.sweep --models all --spatial-code-formats all \ + --input-selections --frames +``` + +6 configs (3 models × {explicit, compact}), input selection and frame count fixed from +Step 1. Aggregate with `analysis.aggregate --harness B`; average "overall" per format +across the 3 models — the argmax format is `format*`. + +**Step 4 — Plan C runs the fully-fixed config.** + +```bash +python -m harness.C.sweep --models all --spatial-code-formats \ + --input-selections --frames +``` + +3 configs (one per model) — every non-model axis is now fixed by Steps 1–3. + +**Step 5 — Plan D: the ground-truth ceiling, run any time after Step 1.** + +```bash +python -m harness.D.sweep --models all +python -m harness.D.symbolic_eval --spatial-code-format explicit +python -m harness.D.symbolic_eval --spatial-code-format compact +``` + +Unlike B and C, D is *not* narrowed to the winning format — it always sweeps both +spatial-code formats × all 3 models, because ground-truth codes cost nothing extra to +build across formats (no encoder GPU pass at all: `encoder.ground_truth` is +annotation-only). Running both is the only way to see whether B's real-perception +format ranking still holds under perfect information. D has no dependency on Steps 2–4 +completing — it can run in parallel with them, since ground truth needs no perceived +spatial code at all. + +**Step 6 — Analysis, after every stage, not gated on the whole plan finishing.** + +```bash +python -m analysis.compare --csv comparison.csv +``` + +Cross-harness comparison (A vs. B vs. C at the frozen config) plus every telemetry-only +hypothesis (H8, H9, H19, H20) that needs no new runs, just the JSONs already on disk. + +**Optional follow-ons**, pursued only if the headline results above warrant it: + +- Re-run Steps 3–4 a second time under the *extended* protocol at the same frozen + config, to get the 16-token-vs-extended comparison (H7, H10) without reopening the + config-selection question. +- The H6 perturbation probe: clone harness C's prompt path with one object's + position/size perturbed in the injected code, on a sample of questions from the + frozen C config. +- Frame-count/selection curves (H14–H16) as an explicitly secondary sweep, re-running + B/C at the other Step-1 frame counts, only if still of interest after the headline + results land. diff --git a/analysis/__init__.py b/analysis/__init__.py new file mode 100644 index 0000000000000000000000000000000000000000..9cdbaada174ab6bb8ffc8499e2a9b6d3bb5a8802 --- /dev/null +++ b/analysis/__init__.py @@ -0,0 +1,10 @@ +"""Analysis over harness.A/B/C results: one shared module, not one per harness. + +Every harness's per-question result record already shares the exact same shape +(model/condition/question_type/metric/score/generation_seconds/...), so there is +nothing harness-specific to reimplement -- only which results directory to read from +differs, and that's a --harness flag / explicit path (see aggregate.RESULTS_DIRS), not +separate code. aggregate.py computes per-category scores (via the real, unmodified +official VSI-Bench aggregator) plus token/latency/forced-answer stats for one harness's +results; compare.py joins all three harnesses' aggregates into one side-by-side table. +""" diff --git a/analysis/__pycache__/__init__.cpython-311.pyc b/analysis/__pycache__/__init__.cpython-311.pyc new file mode 100644 index 0000000000000000000000000000000000000000..f7f722d8b985ec18e76f8bb506f0cae401049681 Binary files /dev/null and b/analysis/__pycache__/__init__.cpython-311.pyc differ diff --git a/analysis/__pycache__/aggregate.cpython-311.pyc b/analysis/__pycache__/aggregate.cpython-311.pyc new file mode 100644 index 0000000000000000000000000000000000000000..858dc0401a6b1bcd5597dabf3906399813924c01 Binary files /dev/null and b/analysis/__pycache__/aggregate.cpython-311.pyc differ diff --git a/analysis/__pycache__/compare.cpython-311.pyc b/analysis/__pycache__/compare.cpython-311.pyc new file mode 100644 index 0000000000000000000000000000000000000000..4139986a6e244a3eb22def27e60f03b9105404c6 Binary files /dev/null and b/analysis/__pycache__/compare.cpython-311.pyc differ diff --git a/analysis/aggregate.py b/analysis/aggregate.py new file mode 100644 index 0000000000000000000000000000000000000000..18b7faff9f0f75548321b1b3a1a21ce14b555b9c --- /dev/null +++ b/analysis/aggregate.py @@ -0,0 +1,228 @@ +"""Aggregate one harness's (A/B/C) per-question result JSONs into per-category scores +(via the real, unmodified official VSI-Bench aggregator -- the same one symbolic/run.py +and harness.A/B/C's own scoring already use) plus token/latency/forced-answer stats. + +One shared implementation for all three harnesses: every result record already carries +the same fields (model/condition/question_type/answer_expected/metric/score/...) +regardless of which harness wrote it, so grouping and scoring are identical; only the +results directory being read differs (see RESULTS_DIRS / --harness). +""" + +from __future__ import annotations + +import argparse +import csv +import json +import statistics +import sys +from collections import defaultdict +from pathlib import Path + +WORKSPACE_ROOT = Path(__file__).resolve().parent.parent +if str(WORKSPACE_ROOT) not in sys.path: + sys.path.insert(0, str(WORKSPACE_ROOT)) + +from harness.A import RESULTS_DIR as HARNESS_A_RESULTS_DIR # noqa: E402 +from harness.A.run import vsi_official_eval # noqa: E402 +from harness.B import RESULTS_DIR as HARNESS_B_RESULTS_DIR # noqa: E402 +from harness.C import RESULTS_DIR as HARNESS_C_RESULTS_DIR # noqa: E402 +from harness.D import RESULTS_DIR as HARNESS_D_RESULTS_DIR # noqa: E402 + +RESULTS_DIRS = { + "A": HARNESS_A_RESULTS_DIR, + "B": HARNESS_B_RESULTS_DIR, + "C": HARNESS_C_RESULTS_DIR, + "D": HARNESS_D_RESULTS_DIR, +} + + +def iter_records(results_dir): + """Yield every per-question result record under ``results_dir``, in a stable + (path-sorted) order.
