Q
What is a Galois field of two elements?
A
A system used to find the dot product of two vectors in a logical way
2
Q
What use is GF2?
A
Adding two vectors is like applying an AND bitwise operator, and multiplying vectors is like applying a XOR bitwise operator

4
Q
Name two ways in which vectors can be expressed
A
As a list or as a mapping of a function onto a list of values
5
Q
What is a convex combination of vectors?
A
If a vector is convex then au +Bv = 1 where a, B > 0
6
Q
What are convex combinations used for?
