Question
A manufacturing company needs to identify returned smartphones that have been damaged by moisture. The company has an automated process that produces 2,000 diagnostic values for each phone. The database contains more than five million phone evaluations. The evaluation process is consistent, and there are no missing values in the data. A machine learning (ML) specialist has trained an Amazon SageMaker linear learner ML model to classify phones as moisture damaged or not moisture damaged by using all available features. The model's F1 score is 0.6. Which changes in model training would MOST likely improve the model's F1 score? (Choose two.)
Options
- AContinue to use the SageMaker linear learner algorithm. Reduce the number of features with the
- BContinue to use the SageMaker linear learner algorithm. Reduce the number of features with the
- CContinue to use the SageMaker linear learner algorithm. Set the predictor type to regressor.
- DUse the SageMaker k-means algorithm with k of less than 1,000 to train the model.
- EUse the SageMaker k-nearest neighbors (k-NN) algorithm. Set a dimension reduction target of
