Which of the following is TRUE regarding the dataset parameters?

Which of the following models are text vectorization methods? (Select two.)

Your dependent variable Y is a count, ranging from 0 to infinity. Because Y is approximately log-normally distributed, you decide to log-transform the data prior to performing a linear regression.
What should you do before log-transforming Y?

You train a neural network model with two layers, each layer having four nodes, and realize that the model is underfit. Which of the actions below will NOT work to fix this underfitting?

Which of the following is NOT a valid cross-validation method?

An organization sells house security cameras and has asked their data scientists to implement a model to detect human feces, as distinguished from animals, so they can alert th customers only when a human gets close to their house.
Which of the following algorithms is an appropriate option with a correct reason?

Given a feature set with rows that contain missing continuous values, and assuming the data is normally distributed, what is the best way to fill in these missing features?

Which of the following can benefit from deploying a deep learning model as an embedded model on edge devices?

Which database is designed to better anticipate and avoid risks of AI systems causing safety, fairness, or other ethical problems?

For each of the last 10 years, your team has been collecting data from a group of subjects, including their age and numerous biomarkers collected from blood samples. You are tasked with creating a prediction model of age using the biomarkers as input. You start by performing a linear regression using all of the data over the 10- year period, with age as the dependent variable and the biomarkers as predictors.
Which assumption of linear regression is being violated?
