Question #3
Q41: A Machine Learning Specialist is building a prediction model for a large number of features using linear models, such as linear regression and logistic regression. During exploratory data analysis, the Specialist observes that many features are highly correlated with each other. This may make the model unstable. What should be done to reduce the impact of having such a large number of features?
A. Perform one-hot encoding on highly correlated features
B. Use matrix multiplication on highly correlated features
C. Create a new feature space using principal component analysis (PCA)
D. Apply the Pearson correlation coefficient

Correct Answer: C
Question #4
Q34: A Data Scientist is developing a machine learning model to predict future patient outcomes based on information collected about each patient and their treatment plans. The model should output a continuous value as its prediction. The data available includes labeled outcomes for a set of 4,000 patients. The study was conducted on a group of individuals over the age of 65 who have a particular disease that is known to worsen with age. Initial models have performed poorly. While reviewing the underlying d
A. Drop all records from the dataset where age has been set to 0
B. Replace the age field value for records with a value of 0 with the mean or median value from the dataset
C. Drop the age feature from the dataset and train the model using the rest of the features
D. Use k-means clustering to handle missing features

Q39: A Machine Learning Specialist built an image classification deep learning model. However, the Specialist ran into an overfitting problem in which the training and testing accuracies were 99% and 75%, respectively. How should the Specialist address this issue and what is the reason behind it?
A. The learning rate should be increased because the optimization process was trapped at a local minimum
B. The dropout rate at the flatten layer should be increased because the model is not generalized enough
C. The dimensionality of dense layer next to the flatten layer should be increased because the model is not complex enough
D. The epoch number should be increased because the optimization process was terminated before it reached the global minimum

Q36: A Machine Learning Specialist deployed a model that provides product recommendations on a company’s website. Initially, the model was performing very well and resulted in customers buying more products on average. However, within the past few months, the Specialist has noticed that the effect of product recommendations has diminished and customers are starting to return to their original habits of spending less. The Specialist is unsure of what happened, as the model has not changed from its initial de Which method should the Specialist try to improve model performance?
A. The model needs to be completely re-engineered because it is unable to handle product inventory changes
B. The model’s hyperparameters should be periodically updated to prevent drift
