Machine Learning

Which of the following statement about machine learning is correct?

• To predict the future

• To generate a model

• To auto- mark answers

• To help us to learn

This scatter plot shows Price Vs RAM size. Which is the target?

• Ram Size

• Price

• NIL

• Both Price and Ram Size

Answer explanation

Target or the Dependent variable is what you are trying to predict.

Supervised Learning is a machine learning approach that is defined by its use of labeled datasets.

• True

• False

Linear Regression Learner attempts to ...

• Predict the Target

• Learn the pattern of the given data set

• Calculate the Root Mean Square Error

• Fit a best straight line between target and independent variables

The Partitioning Node split the data into

• Two duplicates

• Training set and Test set

• 1000 rows each

• Learning set and Predicting set

In the workflow of Supervised machine learning of numerical target, the error is

• Target value - Average value

• Predicted value - Learner value

• Standard deviation

• Predicted value - Observed value

Linear Regression model is a Supervised Learning Approach.

• True

• False
