H2O.ai Certified Machine Learning Practice Questions - H2O.ai Certified Machine Learning (H2O.ai University) Exam - H2O.ai Certified Machine Learning Practice Questions - H2O.ai Certified Machine Learning (H2O.ai University) Exam

Question 1

In H2O-3, what is the primary purpose of calling h2o.init() at the start of a session?

It loads a CSV file directly into a pandas DataFrame It trains a default AutoML model on the most recent dataset It starts or connects the client to an H2O cluster (JVM) that performs the distributed computation It exports the current model as a MOJO scoring artifact

Correct Answer:

It starts or connects the client to an H2O cluster (JVM) that performs the distributed computation

Question 2

When H2OAutoML finishes a binary classification run, which type of model is typically ranked at the top of the leaderboard?

A single Generalized Linear Model (GLM) A Stacked Ensemble that combines the individual base models The Deep Neural Net, because it always generalizes best The first XGBoost model trained, by default

Correct Answer:

A Stacked Ensemble that combines the individual base models

Question 3

By default, how does H2OAutoML rank models on the leaderboard for a binary classification problem?

By RMSE, lowest first By mean per-class error, lowest first By the model's training time, fastest first By AUC, highest first

Correct Answer:

By AUC, highest first

Question 4

In H2OAutoML, which pair of parameters acts as the main stopping criteria, where at least one must effectively be set to bound the run?

nfolds and seed max_models and max_runtime_secs balance_classes and class_sampling_factors stopping_rounds and learn_rate

Correct Answer:

max_models and max_runtime_secs

Question 5

What happens to Stacked Ensembles in AutoML if you set nfolds = 0?

AutoML trains more stacked ensembles than usual Cross-validation is disabled, which also disables Stacked Ensembles unless a blending frame is used AutoML automatically switches to leave-one-out cross-validation Stacked ensembles are still built using the validation_frame's labels directly

Correct Answer:

Cross-validation is disabled, which also disables Stacked Ensembles unless a blending frame is used
