Positional Games are being impacted by a lot of bad data #241

Open Masaya-RT opened 7 months ago

Masaya-RT commented 7 months ago

Main cause is ML usage - Affected GPS utilization due to digital noise -> More inaccurate data for us Every FrameKm has a calculated flag, GPSQuality: Global Filter

Pre-ML, 50% were marked "good" Now, it's at 5%

Jumping on potential fix -> suggestions on reconfiguring course on RasPi CPU

Top Priority today, to stabilize production data Build with Mazar's fixes -> CTP -> Global

Released to Prod in 4.5.12

Fixed CPU frequency and CTP testing is done. We should push to production.

Data seems okay - Just need to finish sensor + visual checks

Masaya-RT commented 7 months ago

Released 4.5.22. Very impactful for GPS quality

Want to Iterate:

  1. Figure out better GNSS config for marking frameKm as Good/Bad - Too aggressive right now. Will work more with DB files we collected. This will improve % of good data (have 40%), want to push closer to 50%
  2. GPS Accuracy: we can tell which users are pushing 100% low-quality data (hundreds of users). Global improvement requires us to discount garbage GPS data collectors. We can try to address this (without a camera replacement) - Mishmear's Fleet Repeaters.

From here

  1. Figure out numbers -> Figure out what to do with it
