B and D
A healthcare analytics company has developed a machine learning model to predict patient outcomes based on historical medical data. During testing, the model demonstrates high accuracy and performs well on the training dataset, but once deployed in a real-world production environment, its accuracy drops significantly when processing new, unseen patient records. The company needs to improve the model’s ability to generalize and perform well on new data, ensuring reliable predictions in the production setting.
What would be the most effective approach to fix this problem?
A. The company should reduce the amount of training data, which can help eliminate noise in the data
B. The company should use hyperparameters for model tuning, which involves adjusting parameters such as regularization, learning rates, and dropout rates to enhance the model’s ability to generalize well to new data
C. The company should swap the existing model with a state-of-the-art generative AI model
D. The company should increase the amount of training data, which can help the model learn more diverse patterns and improve its performance on new, unseen data by exposing it to a wider range of examples
B
A retail company is using an Amazon SageMaker machine learning model to analyze customer purchasing patterns and predict future buying behavior. The data scientists at the company regularly need to process datasets of less than 1 GB, such as daily sales records and customer interaction logs. The company does not require immediate responses and can afford some delay in receiving the analysis results, as the insights are primarily used for weekly strategy meetings.
Which inference method would be the most suitable for the company in this scenario?
A. Real-time inference
B. Asynchronous inference
C. Serverless inference
D. Batch inference
B
A healthcare company is deploying AI systems on AWS to manage patient data and improve diagnostic accuracy.
