A Machine Learning (ML) Specialist Must Develop a Classification Model

question 2

Multiple Choice

A machine learning (ML) specialist must develop a classification model for a financial services company. A domain expert provides the dataset, which is tabular with 10,000 rows and 1,020 features. During exploratory data analysis, the specialist finds no missing values and a small percentage of duplicate rows. There are correlation scores of > 0.9 for 200 feature pairs. The mean value of each feature is similar to its 50th percentile. Which feature engineering strategy should the ML specialist use with Amazon SageMaker?

• A) Apply dimensionality reduction by using the principal component analysis (PCA) algorithm.
• B) Drop the features with low correlation scores by using a Jupyter notebook.
• C) Apply anomaly detection by using the Random Cut Forest (RCF) algorithm.
• D) Concatenate the features with high correlation scores by using a Jupyter notebook.
