GT vs 실제 실행 — 온라인 롤아웃 대조

TL;DR

어제 리포트의 multi 해석을 고친다. "S1/S2는 VLA가 2개를 연속 조작 못 해서 바닥"이라고 썼는데, 물체 단위로 보면 textlog는 direct 0.43 · multi 0.44로 같다. 저하가 없다.
multi SR 0.07의 정체는 결합(p^k) + 예산 초과다: p=0.43이면 두 개 요구 시 기대 0.19, 실측 0.07. 예산 초과가 multi 28% vs direct 13%.
다 하고도 0점인 행이 8개 있다. train_2853__0/textlog는 리모컨 2개를 t2·t4에 실제로 집었는데, 이후 같은 식탁으로 8번 더 이동하다 1543/1500으로 예산 소진 → SR 0.
그 원인은 find의 자동 내려놓기로 보인다 — 집어서 내려놓으면 씬이 그대로라, VLM이 "이미 집었다"고 쓰면서도 완료 선언을 못 하고 같은 곳을 다시 찾아간다.
이미지·요약 전략은 multi에서 물체 단위로도 떨어진다(rf-v3 0.39→0.22, frames 0.33→0.23). 여러 개를 추적하는 데는 명시적 목록(textlog)이 유리하다.
데이터셋 결함 발견 — train_2853__0의 GT 리모컨은 질의 파일에 surface=tv stand로 적혀 있지만 씬에서 실제로는 침대 위에 있다. VLM이 "bed"라고 한 것이 옳았다. 13컨텍스트 86답을 실측한 결과 misplaced="wrong_surface" 답에서만 4/10 불일치(misplaced="no"는 0/70). 채점에는 영향 없다 — 성공 판정은 물체 uid와 씬에서 잰 위치를 쓴다.

1 왜 이 대조가 필요했나

670행 표는 "누가 몇 점"만 말한다. VLM이 실제로 무엇을 지목하고 무엇을 실행했는지를 정답과 나란히 놓고 보면 점수표가 감추던 것이 드러난다 — 실제로 이 대조에서 어제 결론 하나가 틀렸다는 것이 나왔다.

각 사례는 ① 정답(GT 물체 · 방 · surface · 요구 행동) ② 5전략 결과 요약 ③ 두 전략의 턴별 실행 로그(VLM이 지목한 물체/surface/방, 접지 결과, VLA 지시문, 스텝, reasoning 원문) ④ 롤아웃 영상(nav drive + 조작 세그먼트를 시간순으로 이어붙인 것)으로 구성된다. 표에서 붉은 행 ↻은 직전과 완전히 같은 결정을 반복한 턴이다.

2 정정 — multi 셀은 무엇을 재고 있나

어제 670행 리포트에 "S1/S2는 메모리가 아니라 VLA 체이닝 한계를 잰다"고 썼다. 물체 단위로 다시 세어 보니 그 주장은 틀렸다.

전략	direct 물체 단위	multi 물체 단위	multi 기대 SR (p^k)	multi 실측 SR
blind	19/83 = 0.23	16/87 = 0.18	0.05	0.00
textlog	36/83 = 0.43	38/87 = 0.44	0.19	0.07
frames-uniform	27/83 = 0.33	20/87 = 0.23	0.10	0.07
rollforward-v3	32/83 = 0.39	19/87 = 0.22	0.15	0.02
rollforward-vis-pure	29/83 = 0.35	26/87 = 0.30	0.12	0.07

textlog는 물체 단위 성공률이 direct 0.43 → multi 0.44로 그대로다. 개별 물체를 집는 능력은 multi에서 나빠지지 않는다. 그런데 두 개를 모두 요구하니 기대값이 0.19로 떨어지고(결합), 실측은 0.07까지 더 내려간다.

0.19 → 0.07의 추가 손실은 예산이다. multi는 예산 초과가 28%(61/215), direct는 13%(55/415)다. 평균 스텝도 1008 vs 816인데 예산은 둘 다 1500이다. multi 실패 205건의 분해: 하나도 못 들음 115 · 일부만 82 · 전부 들었는데 예산초과 8.

즉 multi 셀은 "메모리가 여러 개를 기억하는가"(textlog는 한다) + "결합" + "예산 안에 두 번 왕복하는가"의 곱이다. VLA의 개별 조작 능력 저하는 아니다 — 다만 이미지·요약 전략(rf-v3 0.39→0.22, frames 0.33→0.23)은 물체 단위로도 떨어져, 여러 개를 추적하는 데 명시적 목록이 유리하다는 별개의 신호가 있다.

반복 결정(루프)은 multi 전용 현상이 아니다. 직전과 같은 결정을 3회 이상 연속한 행이 multi에서 blind 20/43 · textlog 16/43인데, direct에서도 blind 44/83 · textlog 36/83이다. 루프는 전반적 실패 모드이므로 multi 설명으로 쓸 수 없다 — 다만 예산이 빠듯한 multi에서 손실이 점수로 바뀐다.

데이터셋 surface는 질의 파일의 answers[].surface, 실제 support는 복원된 씬에서 잰 지지 부모다. 둘이 다른 행은 붉게 표시했다 — misplaced="wrong_surface" 답에서만 나타난다(측정 4/10). 참고: 행 필드 gt_ground_strict.hit은 "GT 물체가 후보에 있다" 또는 "답의 surface 가구를 찾았다" 중 하나만 참이어도 True라, surface가 틀린 행에서도 ✔가 되므로 여기서는 쓰지 않는다.

8 데이터셋 점검 — GT surface 필드가 씬과 다른 답이 있다

위 train_2853__0 사례에서 VLM 둘 다 "bed"라고 답했는데 GT 표기는 "tv stand"였다. 어느 쪽이 맞는지 씬을 복원해 직접 쟀다(build_support_of, 렌더 없이 1회 로드).

GT remotecontrol_9e0a946e..._2_0_7 데이터셋 surface = stand_ed4e820a..._1_0_4 (tv stand) misplaced="wrong_surface" 실제 support_of = bed_d62dc7f8..._1_0_4 (bed) 물체 중심 [5.37, 2.02, 0.42] = 데이터셋 xyz [5.368, 2.015, 0.421] ← xyz는 맞고 surface uid만 다르다

그 침실에는 리모컨이 4개 있다 — tv stand 위 2개(미끼), 침대 위 1개(GT #1), 그리고 거실 식탁 위 1개(GT #2). strict 접지를 두 답으로 각각 돌려보면 surface="bed"는 GT #1로, surface="tv stand"는 미끼 쪽으로 간다. 즉 GT 표기대로 답했으면 틀린 물체로 갔을 것이다.

구분	측정	불일치
13컨텍스트 · surface 기재된 답	80	4 (5.0%)
└ `misplaced="wrong_surface"`	10	4
└ `misplaced="no"`	70	0
surface 미기재(null) — 전부 D3	6	— (기록 안 함, 결함 아님)

데이터셋 전체 find 답 645개 중 wrong_surface는 28개(surface 기재분)다. 측정 불일치율 40%를 적용하면 약 11개(1.7%)가 실제와 다른 surface를 갖는다. misplaced="no" 538개는 표본에서 불일치 0이었다.

채점에는 영향이 없다. 성공 판정은 답의 물체 uid와 복원된 씬에서 잰 gt_positions 거리를 쓰지, 데이터셋의 surface 문자열을 쓰지 않는다. 영향 범위는 진단 필드 gt_ground_strict와 리포트 표시뿐이다 — 그래서 위 GT 표에 실측 support를 병기했다.

9 정리

multi 셀 서술을 바꿔야 한다. "VLA 체이닝 한계"(어제) → "메모리 × 결합 × 예산"의 곱. 물체 단위로는 textlog가 direct와 동일하다.
자동 내려놓기 재검토가 필요하다. find는 다음 물체로 넘어가려고 집은 것을 내려놓게 되어 있는데(260907 결정), 그 결과 씬이 원상복귀돼 VLM이 완료를 인지하지 못하고 같은 목적지를 반복한다. multi 질의에서만 문제가 되므로, multi에 한해 든 채 유지하거나 "이미 집은 물체" 목록을 관측에 넣는 선택지가 있다 — 프로토콜 변경이라 사용자 결정 사항.
D3(은닉)은 두 전략 모두 실패한다. 기억이 위치를 알려줘도 닫힌 곳을 여는 데서 막힌다(open 실성공률은 파일럿4에서 1/55).
