Change History

Change History#

Note these changes related to eyeballing strategy rather than focusing on the GH site since the history of the latter is recorded in the commit history.

VRA 1.1 - 2025-03-06 - Duck

  • day N feature DET_mag_median added back in. Marginal gains but also consistent with keeping NON_mag_median and removing both is worse.

  • day 1 and day N feature DET_mag_median_min5d added in.

  • Although the clean data we use is the same, the training and validation sets have changed from Duck (Crabby data set is unchanged all changes below apply to the additional data gathered between august and january).

  • The training set no longer includes “guessed” labels.

  • The training set is balanced with 1500 auto-garbage and 500 garbage examples (for a total of 2k additional bogus examples). That subdivision reflects the fraction of auto-garbage and garbage in our additional data.

  • When training the galactic classifier, the garbage and auto-garbage are no longer used during training. Instead only the PM, Galactic and Good alerts are used.

  • When ranking the scalar (or fudge factor) has been changed back to 0.5.

  • Extra galactic eyeballing threshold is now 7 instead of 7.5

  • The Galactic flag is calculated using a scalar of 0.9 instead of 1 and a distance of 0.4 instead of 0.45.

  • Fix the purgatory bot

VRA 1.0 - 2025-02-03 - Duck

  • VRA real and galactic models trained on the Duck data-set. Ranges from 27-03-2024 to 22-01-2025

  • The following day1 features were pruned: SN`, ORPHAN, NT, UNCLEAR

  • The following dayN features were pruned: SN, ORPHAN, NT, UNCLEAR, DET_N_today, NON_N_today, DET_mag_median

  • Eyeballing now split into extragalactic and galactic

  • Eyeball list now named extragalactic candidate list (although purgatory objects still linger at the bottom of that list)

  • Extra galactic candidates defined as rank > 7.5 (instead of 4)

  • Galactic candidates defined as within 0.45 of the top right corner of score space (fudge-factor = 1 instead of 0.4)

  • ScoreAndRank now has the is_gal_cand property (boolean flag)

  • Auto-garbaging strategy modified: day1: max_rank <1 (was 1.5), day2: max_rank < 2 (was 3), day3+ : mean_rank <3 (unchanged).

  • Number of alerts reported by slack-bot no longer overestimated

  • el01z weekly reports and purgatory sentinel now run on the ATLAS server (Fridays)

  • TNS cross-matching to garbage list done weekly on Friday mornings

VRA beta0.1 - 2024-12-06 - Crabby

  • VRA real and galactic models trained on the Crabby data-set. Ranges from 27-03-2024 to 13-08-2024

  • Fudge-factor changed to 0.4 (from 0.5)

  • added new sherlock features: z, photoz, log10 sep arsec, ebv sfd

VRA alpha0.1 - 2024-13-08 - BMO

  • First VRA in production
