A new column was added to the input data.No one thought it would affect the model.Suddenly, inference started failing or producing nonsense results.This keeps happening as systems evolve.
Decode Trail Latest Questions
My production data is unlabeled.I can’t calculate accuracy or precision anymore.Still, I need to know if the model is degrading.What can I realistically monitor?
I retrained my model with more recent data.The assumption was that newer data would improve performance.Instead, the new version performs worse in production.This feels counterintuitive and frustrating.
Feature distributions look stable.But prediction quality is declining.Simple drift metrics don’t explain it.Something deeper seems wrong.
Training loss decreases smoothly.Validation loss fluctuates.Regularization is enabled.Still, generalization is poor.
I trained a model that performed really well during experimentation and validation.The metrics looked solid, and nothing seemed off in the notebook.However, once deployed, predictions started becoming unreliable within days.I’m struggling to understand why production behavior is ...
Offline metrics improved noticeably.But downstream KPIs dropped.Stakeholders lost confidence.This disconnect is concerning.
I rerun the same experiment multiple times.Metrics fluctuate even with identical settings.This makes comparisons unreliable.I’m not sure what to trust.
My deployed model isn’t crashing or throwing errors.The API responds normally, but predictions are clearly wrong.There are no obvious logs indicating failure.I’m unsure where to even start debugging.
Traffic is stable.Model architecture hasn’t changed.Yet costs keep rising month over month.It’s hard to explain.
