A data scientist has explored and sanitized a dataset in preparation for the modeling phase of a supervised learning task.The statistical dispersion can vary widely between features, sometimes by several orders of magnitude.Before moving on to the modeling phase, the data scientist wants to ensure that the prediction performance on the production data is as accurate as possible.Which sequence of steps should the data scientist take to meet these requirements?
A government agency is conducting a national census to assess program needs by area and city. Thecensus form collects approximately 500 responses from each citizen. The agency needs to analyzethe data to extract meaningful insights. The agency wants to reduce the dimensions of the highdimensionaldata to uncover hidden patterns.Which solution will meet these requirements?
A company wants to build an anomaly detection ML model. The model will use large-scale tabulardata that is stored in an Amazon S3 bucket. The company does not have expertise in Python, Spark,or other languages for ML.An ML engineer needs to transform and prepare the data for ML model training.Which solution will meet these requirements?
A company runs an ML model on Amazon SageMaker AI. The company uses an automatic processthat makes API calls to create training jobs for the model. The company has new compliance rulesthat prohibit the collection of aggregated metadata from training jobs.Which solution will prevent SageMaker AI from collecting metadata from the training jobs?
A travel company has trained hundreds of geographic data models to answer customer questions byusing Amazon SageMaker AI. Each model uses its own inferencing endpoint, which has become anoperational challenge for the company.The company wants to consolidate the models' inferencing endpoints to reduce operationaloverhead.Which solution will meet these requirements?
