Finding value of theta in linear classification I have an examing coming up, and I'm practicing with exams from previous years. However, the answers to the questions are not provided unfortunately.
I'm currently doing the question below, and the intuitive answer I get is 2. However, this seems too easy. Am I correct?
Since it is an exam question, I will give you hints and leading questions instead of answers.
Note that $x^T w$ must be well-defined, and $x$ is 2-dimensional. What is the dimension of $w$?
How is bias incorporated into the model?
The margin satisfies $\widehat{y} = 0.$ What is the equation of the margin (as a function of x and bias)?
P.S. I expect a typo/vagueness in this question.
