About Multiple Linear Regression Lab

This is the first time I have come across theta in the course.
I can’t figure out what this means.
Did I miss or overlook something?

Please help.

Hello @mr_raven,

Sometimes people refer the collection of model parameters as theta. Here, the model parameters are w_in and b_in.

The function markup probably should refer to “weights and bias”, since that’s the terminology used in the lectures.
