RoboMME-Interference

Every rollout from RoboMME-Interference, a cross-session benchmark that measures whether a memory-augmented robot policy can still use a relevant past session once unrelated sessions accumulate in its history.

The benchmark is built on RoboMME (Dai et al., ICML 2026), reusing its tasks, memory-augmented π₀.₅ variants, and released checkpoints. This dataset is the evaluation output, not robot data: one row per rollout, with the outcome and the composition of the history buffer the policy was given.

The protocol

For each query episode, the policy is given an external history buffer holding the episode's relevant prior demonstration (the lesson), followed by k unrelated distractor sessions from other task families. Larger k pushes the lesson farther back.

condition	History buffer contents
no-history	empty
k0	the lesson only
k1, k3, k7	the lesson, then 1, 3, or 7 unrelated sessions

Eight memory systems, each across nine task families, five conditions, and 50 test episodes, gives 18,000 rollouts. The π₀.₅ baseline has no memory and appears only at no-history, adding 450, for 18,450 rollouts over 369 cells.

Scoring convention

Success rate is successes / 50 per cell. Episodes that hit the step limit have status == "ongoing" and count as non-successes: they stay in the denominator. Filtering them out inflates every rate.

from datasets import load_dataset

ds = load_dataset("SoumilR/robomme-interference", split="test")
cell = ds.filter(lambda r: r["variant"] == "perceptual-framesamp-modul"
                       and r["family"] == "MoveCube" and r["condition"] == "k7")
rate = sum(r["status"] == "success" for r in cell) / len(cell)  # 0.32

Configs

Config	Rows	Contents
default	18,450	every rollout across all nine systems (canonical_rollouts.csv)
retrieval	1,800	rollouts for Retrieval-FrameSamp-Modul (retrieval_rollouts.csv)
success_rates	41	per-system, per-condition success rates with Wilson 95% intervals

tables/ also holds success rates per family and per difficulty, each system's lift over its own no-history rate, and the k0-to-k7 drops.

Columns

Shared by both rollout files:

Column	Description
family	task family: MoveCube, RouteStick, VideoUnmask, VideoUnmaskSwap, VideoRepick, VideoPlaceButton, VideoPlaceOrder, InsertPeg, PatternLock
condition	no-history, k0, k1, k3, k7
episode	test-episode index, 0–49; the same identity across conditions, so comparisons are paired
seed	simulator seed
difficulty	RoboMME's easy / medium / hard stratification
status	success, fail, or ongoing (hit the step limit)
success	boolean, equivalent to status == "success"
steps	environment steps taken

canonical_rollouts.csv adds:

Column	Description
variant	one of perceptual-{framesamp,tokendrop}-{modul,context,expert}, recurrent-ttt-{context,expert}, pi05_baseline
distractors	number of unrelated sessions in the buffer
buffer_frames_start, buffer_frames_end	buffer size in frames, before and after the rollout
actual_*_lesson,filler,query and *_fraction	how much of the buffer came from the lesson, the distractors, and the live query episode, at rollout start and end
timing and cache columns	wall-clock and server-side latency per phase, feature-cache hit counts

retrieval_rollouts.csv adds:

Column	Description
retrieval_model	encoder and segmentation setting used for retrieval
retrieval_selected_{lesson,filler,query}_fraction	share of the retrieved segment that came from the lesson, the distractors, and the query episode

The mean retrieval_selected_lesson_fraction is 0.96, so what retrieval delivers to the policy is almost entirely the lesson.

Variant names

Paper names map to variant values as FrameSamp → framesamp, TokenDrop → tokendrop, Recurrent-TTT → recurrent-ttt, and the integration suffixes -Modul, -Context, -Expert → -modul, -context, -expert.
