    Hi,

    Would you mind telling why in the first BPM example in the tutorial the vector x is augmented by 1?

    Can't we use a 2x2 matrix w instead of a 3x3?

    Thanks

    This is a constant input whose corresponding weight acts as a bias term to shift decision boundaries away from the origin in input space.
