SageMaker Autopilot supports training ML models with weights, eight additional objective metrics

Amazon SageMaker Autopilot, a low-code machine learning (ML) service which automatically builds, trains and tunes the best ML models, now supports training with weighted objective metrics in Ensemble mode and also supports eight additional objective metrics. Assigning weights to each data sample in the training data set can improve overall model performance by helping the model learn better, reduce bias towards a particular class, and increase stability.
