Question & Answer
Choose the Best Answer
It allows for the efficient computation of the cost function across multiple data points.
It transforms the dataset into a non-linear space.
It increases the dimensionality of the input features.
It decreases the number of iterations needed to converge.
Understanding the Answer
Let's break down why this is correct
Matrix multiplication lets us compute predictions for all training points at once. Other options are incorrect because Some think matrix multiplication turns data into a non‑linear space; A common misconception is that matrix multiplication adds more features.
