A function for Generating a quadratic simulation.
1 | mgc.sims.quad(n, d, eps = 0.5, ind = FALSE, a = -1, b = 1)
|
n |
the number of samples for the simulation. |
d |
the number of dimensions for the simulation setting. |
eps |
the noise level for the simulation. Defaults to |
ind |
whether to sample x and y independently. Defaults to |
a |
the lower limit for the data matrix. Defaults to |
b |
the upper limit for the data matrix. Defaults to |
a list containing the following:
|
|
|
|
Given: w[i] = 1/i is a weight-vector that scales with the dimensionality.
Simulates n
points from Quadratic(X, Y) where:
X ~ U(a, b)^d
,
Y = (w^TX)^2 + K*eps*N(0, 1)
and K = 1 if d=1, and 0 otherwise controls the noise for higher dimensions.
