Question

You work at an ecommerce startup. You need to create a customer churn prediction model. Your company's recent sales records are stored in a BigQuery table. You want to understand how your initial model is making predictions. You also want to iterate on the model as quickly as possible while minimizing cost. How should you build your first model?

Why each option

To build a customer churn prediction model quickly and cost-effectively from BigQuery data while understanding its predictions, the best approach is to prepare the data in BigQuery and use Vertex AI AutoML.

AExport the data to a Cloud Storage bucket. Load the data into a pandas DataFrame on Vertex AI

Exporting data to Cloud Storage and loading into a pandas DataFrame on Vertex AI Workbench requires significant manual coding for model building, which is not the quickest or most cost-effective approach for an initial model.

BCreate a tf.data.Dataset by using the TensorFlow BigQueryClient. Implement a deep neural

Creating a `tf.data.Dataset` and implementing a deep neural network demands substantial manual effort and expertise, conflicting with the goal of quick iteration and cost minimization for a first model.

CPrepare the data in BigQuery and associate the data with a Vertex AI dataset. Create anCorrect

Vertex AI AutoML is designed for rapid model development with minimal code, offering features to understand model predictions and optimize for cost by reducing manual effort. Associating BigQuery data with a Vertex AI dataset streamlines the data ingestion for AutoML tabular models.

DExport the data to a Cloud Storage bucket. Create a tf.data.Dataset to read the data from Cloud

Exporting data to Cloud Storage and using `tf.data.Dataset` for reading still implies a custom model development path, which is more complex than leveraging AutoML for rapid prototyping and iteration.
