- The wrist view is what the model was trained on, so why did it not help?
- How can a model that never aims at a glass break twenty of them?
- Why did the model never say "done" on its first walk?
- The share rose from 0.018 to 0.439, so did the model get better?
- Why does it reach fewer tables now that it breaks nothing?
1. The wrist view is what the model was trained on, so why did it not help?#
The picture was not what moved the answers. A check kept the old parked pose and gave only the wrist picture. The answers stayed as high as before. The answers came down because the model was told a real pose near the table. The wrist camera did not bring the answers down shows the three runs.
2. How can a model that never aims at a glass break twenty of them?#
Its paths are long and cross the whole glass zone. The fingers hang about 70 mm below the path's height, so they sweep the tops of the glasses. A glass hit near its top tips. Aiming at nothing is worse than not arriving explains it.
3. Why did the model never say "done" on its first walk?#
The shared rule waits for a run of answers that cannot touch a glass. Almost every answer came low enough to touch one. So the run never formed, and a table ended only when a glass fell or time ran out. The first walk broke twenty glasses gives the numbers.
4. The share rose from 0.018 to 0.439, so did the model get better?#
No. A table that loses a glass earns nothing. Once no table was lost, the glasses that started with room were counted. They are 16 of the 18 pickable glasses at the end. The model itself freed only two. What the held-out queue measured reads the columns.
5. Why does it reach fewer tables now that it breaks nothing?#
A raised answer still costs the arm its move. The stopping rule needs 16 quiet answers in a row before it ends a table. So a table now costs about 19 answers and 80 arm seconds. Before, a falling glass ended the table early. What the held-out queue measured has the count.
