Jaiveer Bassi (imjbassi): Robotics, Skoor 60

What they built

Jaiveer Bassi built an audit of two published trajectory-smoothness metrics, SAL and TED, used to curate imitation-learning demonstrations, run on robomimic with episode-length controls [source]. When demonstration durations are matched, SAL detects operator skill at AUROC 0.628 and TED at 0.359, which is below chance, while jerk scores 0.896 [source]. Without length control, episode length alone scores 0.957, close to SAL's 0.952 [source]. On can/mg, filtering by any tested metric produced a worse policy than no filtering (TED 0.216 vs. 0.408, 5 seeds) [source]. The repo includes a 35-run training grid that takes about 27 hours on one GPU [source].

Inference: This is an evaluation and critique of existing curation metrics. It is not a product.

Record

Measured signals (n=4, confidence 0.8):

Code author for the paper (weight 20) [source].

First author, published 2026-10-12 (weight 15) [source].

39 commits in 90 days on the audit repo (weight 15) [source].

958 commit contributions in the last year (weight 10) [source].

The repo has 1 star and 0 forks, and it was created 2026-08-30 [source]. The profile shows 4 followers, location CA, USA, and the bio "upload projects for fun" [source]. No paper affiliation is listed [source].

Inference: The paper appears at both first and last author positions, which suggests sole authorship [source].

Why now

The audited metrics come from *rinse* (arXiv:2604.23000) [source]. The audit followed within months.

Inference: Demonstration-data curation for imitation learning is an active research area. Market timing and commercial demand are not in the evidence.

Unknowns

Company, funding, employer, education: not in the evidence.
Commercial intent: not in the evidence.
Where the other ~919 yearly commits went: not in the evidence.
TED was reimplemented from the *rinse* appendix, not the authors' code [source].
The results cover only the robomimic "can" task [source].

Questions for the room

TED's inverted AUROC of 0.359 comes from a reimplementation. Have you checked it against the *rinse* authors' code or contacted them?
Does the downstream result (0.216 vs. 0.408 on can/mg, 5 seeds) hold on tasks other than "can"?
Your bio says "upload projects for fun." Of the 958 commits last year, how many were robotics work, and are you building toward a company?

What would move the Skoor

It would go up with confirmation that TED matches the reference implementation, results on more tasks, or evidence of a venture or affiliation. It would go down if the inversion disappears under the authors' code.
