Meeting Notes
Attendees: Thomas, Patrick, David, Torri, Hovanes, Jiawei, Cristiano, Armen, Naomi
- Lawyers happy on both sides now
- Conference preparations underway
Progress
-
Patrick
- Diamond dosage
- Reached out to Jiawei
- Jiawei tried some suggestions from Hovanes and couldn’t come up with any absolute location dosage.
- David reiterated the use of relative positions.
- Hovanes was hoping that a combination of Richard’s scan would yield the edges/absolute position.
- Hovanes asked Jiawei if the web interface was used.
- Jiawei showed some plots of the diamond scans (comparing Richard to Hovanes)
- Very hard to orient.
- Hovanes offered some suggestions on how to match up but agreed that with what Jiawei looked at, they can’t be matched up.
- David asked about seeing what the nudge actually does (with respect to the coherent edge) as well as drift over time.
- Patrick showed some of the GPR results on delta c predictions from delta E.
- Naomi asked about using a stable beam only.
- Armen suggested other kernels/noise to enhance.
-
Armen
- Showed some slides
- Plot of reward vs position of edge vs required edge
- Did not like the possibility of getting a negative reward close to the required beam.
- Changed reward to a step function… still not happy.
- New environment: Normalize action/observation space.
- Better reward distribution achieved!
- Showed some TensorBoard plots about the training.
- Reiterated the point that normalization is not preferred but saw evidence that a norm was needed.
Milestone Review
- Out of time. Please review the milestones (Patrick) 1-4 and address or tidy up.
