| wolffd@0 | 26 </h2> |
| wolffd@0 | 27 |
| wolffd@0 | 28 <p><CODE>net = mdninit(net, prior)</CODE> takes a Mixture Density Network |
| wolffd@0 | 29 <CODE>net</CODE> and sets the weights and biases by sampling from a Gaussian |
| wolffd@0 | 30 distribution. It calls <CODE>mlpinit</CODE> for the MLP component of <CODE>net</CODE>. |
| wolffd@0 | 31 |
| wolffd@0 | 32 <p><CODE>net = mdninit(net, prior, t, options)</CODE> uses the target data <CODE>t</CODE> to |
| wolffd@0 | 33 initialise the biases for the output units after initialising the |
| wolffd@0 | 34 other weights as above. It calls <CODE>gmminit</CODE>, with <CODE>t</CODE> and <CODE>options</CODE> |
| wolffd@0 | 35 as arguments, to obtain a model of the unconditional density of <CODE>t</CODE>. The |
| wolffd@0 | 36 biases are then set so that <CODE>net</CODE> will output the values in the Gaussian |
| wolffd@0 | 37 mixture model. |
