x
and one target variable t
with data generated by
sampling t
at equal intervals and then generating target data by
computing t + 0.3*sin(2*pi*t)
and adding Gaussian noise. A
Mixture Density Network with 3 centres in the mixture model is trained
by minimizing a negative log likelihood error function using the scaled
conjugate gradient optimizer.
The conditional means, mixing coefficients and variances are plotted
as a function of x
, and a contour plot of the full conditional
density is also generated.
