New Performance Metric: Symmetric Mean Absolute Percentage Error (sMAPE)

Arize users can now use Symmetric Mean Absolute Percentage Error as an accuracy metric for performance tracing. sMAPE is useful when your model is prone to over forecasting, and the shortcomings of MAPE become prohibitive for evaluating accuracy.

Support Latent Tags On Actuals
Arize users can now log latent actuals with tags. This enables users with delayed actuals to group, monitor, slice, and investigate the performance of delayed cohorts. Latent tags broadens the scope of our existing metadata monitoring features for more comprehensive ML observability.
