Lecture 13

Question 1

What does it mean if our equation is linear in parameters?

Answer 1

linear combination of non-linear functions of the features

Question 2

What is feature engineering?

Answer 2

the process of creating new features out of existing information in our dataset

Question 3

What will feature engineering be restricted to in our class?

Answer 3

creating non-linear functions of existing features

Question 4

What condition must be satisfied in order for us to have any number of parameters?

Answer 4

our hypothesis function should be linear in the parameters

Question 5

What is the goal of all this?

Answer 5

to find a hypothesis function that will generalize well to unseen data

Question 6

What is Amdahl’s Law?

Answer 6

relates to the runtime of a program on p processors to the time to do the sequential and non-sequential parts on one processor

Question 7

What is the equation for Amdahl’s Law?

Answer 7

H(p) = t_s + t_NS / p
