Project Status

This is the fastest way to understand the current research project state. It summarizes what has already been implemented from the public Xperience-10M sample, what the first multi-episode Qwen3-Omni diagnostic pilot shows, and which artifacts support the next development step.

Research Positioning

The project is a research-engineering study of Xperience-10M rather than a single demo result. It makes the public sample episode inspectable, defines embodied-AI tasks over synchronized modalities, records baseline behavior, and keeps the next multi-episode modeling stage explicit. The current evidence is useful for judging data understanding, task design, evaluation discipline, and scale-up readiness; it is not presented as final full-dataset model quality.

Area	Current state	Evidence	Research readout
Public-sample pipeline	Verified	results/episode_task_suite/summary_report.json, results/episode_task_suite/windows.csv, results/episode_task_suite/feature_manifest.json	One public Xperience-10M sample episode is converted into 5,821 frames, 1,161 aligned 20-frame windows, and an 8,546-dimensional current feature contract.
Task suite	Verified	scripts/episode_task_suite.py, results/episode_task_suite/, docs/data/summary_metrics.json	All 12 task contracts have committed metrics, predictions, and minimal baseline outputs.
Neural heads	Verified	scripts/neural_task_models.py, results/episode_task_suite/neural_mlp/	Each task also has a compact PyTorch MLP run over the same feature tensor and chronological split.
Audio contribution study	Verified	scripts/audio_ablation_and_raw_upgrade.py, results/audio_ablation/, docs/data/audio_ablation_summary.json	Audio variants are compared across all 12 task contracts; audio improves the primary metric on 6 of 12 tasks, and a 588-d audio-window representation improves over the baseline audio variant on 6 of 12 tasks.
Research takeaways	Verified	RESEARCH_TAKEAWAYS.md, docs/data/research_takeaways.json, scripts/build_research_takeaways.py	The main result interpretation is generated from committed metrics: chronological class shift, neural gains on dynamics/order/alignment, open retrieval/reconstruction problems, and the need for held-out episodes.
Research roadmap	Current	RESEARCH_ROADMAP.md, docs/data/research_roadmap.json	The roadmap connects public-sample task development to the verified validation-aware Qwen3-Omni diagnostic baseline, structured-output improvement pass, robustness runs, world/policy branches, and the future Xperience-native pretraining goal.
Foundation-model plan	Current	FOUNDATION_MODEL_PLAN.md, docs/data/foundation_model_plan.json	Qwen3-Omni remains the first trainable held-out LoRA baseline; Cosmos 3 is added as the first world-model/action-generation branch; OpenVLA/openpi/GR00T are policy candidates after action targets are explicit.
Xperience Embodied Foundation Model	Future goal	XPERIENCE_EMBODIED_FOUNDATION_MODEL_PRETRAINING.md	A future full-corpus pretraining plan describes target modules, objectives, staged scale-up, hardware ranges, and evaluation for a domain-specific embodied foundation model.
Evaluation protocol	Verified	EVALUATION_PROTOCOL.md, docs/data/evaluation_protocol.json, scripts/build_evaluation_protocol.py	Windowing, chronological split, per-task metrics, leakage controls, and current limitations are generated from committed metric artifacts.
Dataset context	Verified	XPERIENCE10M_DATASET_CARD_ALIGNMENT.md, official Xperience-10M and sample cards	The README and dashboard distinguish the public sample used here from the gated full dataset used for the selected multi-episode pilot.
Public dashboard and Hub pages	Verified	GitHub Pages, HF Space, artifact dataset, baseline model repo, Qwen3-Omni LoRA repo	Readers can move between the website, code, derived artifacts, baseline weights, and Qwen3-Omni pilot status without needing local infrastructure details.
Public package policy	Verified	DATA_NOTICE.md, REPRODUCIBILITY.md	Raw Xperience-10M data, private gated files, large archives, credentials, and full Qwen weights are not redistributed.
Reproducibility	Verified for the public sample	REPRODUCIBILITY.md, docs/data/reproducibility_matrix.json, notes/reproducibility_audit.md	The public sample workflow has explicit commands, expected outputs, and exact-match reproduction evidence.
Qwen3-Omni fine-tuning	Verified validation-aware diagnostic held-out pilot; quality target not met	docs/data/omni_finetune_verified_result.json, results/omni_finetune/verified_public/, scripts/omni/package_verified_omni_result.py, scripts/omni/audit_verified_omni_package.py	The selected 96/16/16 episode split produced a validation-aware public-safe held-out package with 3,808 exported windows, 512 validation windows, and 448 test predictions. JSON validity is 87.50%, below the 98% target, so the result is a diagnostic baseline and the next pass should focus on structured-output improvements and error analysis.
Raw Xperience-10M redistribution	Not included	DATA_NOTICE.md, docs/data/publication_audit.json	Raw MP4, HDF5, RRD files, private gated data, and full Qwen weights are intentionally excluded.

8. Inspect results/audio_ablation/AUDIO_ABLATION_SUMMARY.md before judging whether audio helps the current task suite.
9. Inspect EVALUATION_PROTOCOL.md before judging task metrics or leakage controls.
10. Inspect XPERIENCE10M_DATASET_CARD_ALIGNMENT.md only if you need the detailed upstream dataset-card context.
11. Inspect docs/data/omni_finetune_verified_result.json before judging the Qwen3-Omni diagnostic pilot.

Current Reading Notes

• Cross-episode generalization is a later multi-episode evaluation target; the current results use one public sample episode.
• Public-facing fine-tuning results should come from the verified result package, not from live process logs or setup-only artifacts.
• The first Qwen3-Omni held-out package verifies the pipeline, not strong model quality: JSON validity is 87.50%, action macro-F1 is 0.0027, and subtask accuracy is 0.0067.
• The current reconstruction task reconstructs feature vectors, not pixel depth, meshes, NeRF outputs, or Gaussian splats.
• Audio is part of the current 8,546-dimensional baseline feature vector.
• Audio contribution is evaluated across all 12 task contracts in results/audio_ablation/.
• Foundation-model selection is now explicit: Qwen3-Omni is the immediate trainable pilot, Cosmos 3 is the first world-model branch, and policy models such as OpenVLA/openpi/GR00T wait for action-target conversion.
• The Xperience Embodied Foundation Model is a future native-pretraining goal, not a completed model or current benchmark.
