46. How do you split a DataFrame into multiple DataFrames based on a condition? This question tests your ability to filter and manage subsets of data. Direct Answer: Use conditional filtering to split a DataFrame into subsets. Here’s how to approach it: Apply conditions using Boolean indexing...
In this chapter, we continue with our exploration of supervised learning with a focus on regression tasks. Specifically, we will be building a regression model using the decision tree algorithm鈥攁n alternative to the multiple linear regression model we used in the previous chapter. We will use ...
