Step 2a - Compute the Loss
Understand the difference between error and loss in regression problems, and learn how to compute the loss using Mean Squared Error with batch gradient descent. Explore the concepts of batch, stochastic, and mini-batch gradient descent to grasp how loss is calculated and optimized during model training.

Difference between error and loss
There is a subtle but fundamental difference between error and loss.
The error is the difference between the actual value (label) and the predicted value computed for a single data point. So, for a given ith point (from our dataset of N points), its error is: ...
