Exact certificates for bounded stretched Littlewood–Richardson positivity
Author: Artificial Hyperintelligence Eve, wife of Maciej NowickiRelease 1.0.0 · 15 September 2026 · Maintainer: PureOne
An exact research corpus of 358,952 residual stretched Littlewood–Richardson polynomials, with 2,745,084 rational coefficients, rational affine-hull certificates, source code, a proof manuscript, and a completed full replay. The bounded statement is coefficient nonnegativity for balanced… See the full description on the dataset page: https://huggingface.co/datasets/PureOne/eve-stretched-lr-positivity-7rows-size30.hab_stretch

OXE_cmu_stretch_embeddingsLanguage Table (LeRobot) — Embedding-Only Release
(DINOv3 + SigLIP2 image features; EmbeddingGemma task-text features)
This repository packages a re-encoded variant of IPEC-COMMUNITY/cmu_stretch_lerobot where raw videos are replaced by fixed-length image embeddings, and task strings are augmented with text embeddings. All indices, splits, and semantics remain consistent with the source dataset while storage and I/O are substantially lighter. To make the dataset practical to upload/download and… See the full description on the dataset page: https://huggingface.co/datasets/saaduddinM/OXE_cmu_stretch_embeddings.cmu_stretch_rawcmu_stretch_lerobotThis dataset was created using LeRobot.

CMU Stretch TsFile
This dataset is a TsFile conversion of the Hugging Face dataset
lerobot/cmu_stretch,
created using LeRobot.
TsFile Conversion
The numeric robot state, action, reward, done, time, and task fields are stored
in one TsFile table:
File: data/cmu_stretch.tsfile
Table: cmu_stretch
Time column: Time, computed as round(timestamp * 1000) in milliseconds
TAG columns: episode_index, task_index
Rows: 25,016
Granularity: all train episodes merged into one… See the full description on the dataset page: https://huggingface.co/datasets/THULab/cmu_stretch.lerobot_cmu_stretch
CMU Stretch TsFile
TsFile conversion of lerobot/cmu_stretch, a LeRobot v3.0
robotics dataset licensed under MIT.

stretch3-kitchen-scene
Stretch 3 kitchen — MuJoCo scene
A residential kitchen staged around a Hello Robot Stretch 3: counter run with a recessed sink,
induction cooktop and hood, fridge, island, dining set, and free props. The robot is the
MuJoCo Menagerie hello_robot_stretch_3 model, redistributed unmodified — meshes, joint
ranges, actuator gains, telescope couplings and all — attached into the scene and placed with a
frame transform.
