Empirical Risk Minimization
easy

A data scientist is tasked with building a predictive model to forecast sales based on historical data. To ensure the model performs well, they decide to apply empirical risk minimization (ERM). Which of the following actions best represents the application of ERM in this scenario?

Choose AnswerChoose the Best Answer

A

Selecting the model with the highest complexity to capture all potential patterns in the data.

B

Choosing the parameters that minimize the average loss of the model on the training dataset.

C

Randomly adjusting parameters until the model performs well on the training set.

D

Using the same parameters from a previous project without considering the current dataset.

Understanding the Answer

Let's break down why this is correct

ERM means we look at the training data and pick the model settings that make the average error as small as possible. Other options are incorrect because Choosing the most complex model is a common mistake; Randomly tweaking parameters is like guessing on a test.
