|
Uses the already trained model to predict output values for new inputs provided in the parameter,this method returns the complete multivariate gaussian distribution resulting from the regression process.
- Parameters
-
new_data | : A vector of matrices containing points for which output data is unknown in one or more of the output classes. |
vector< double > gplib::gp_reg_multi::get_params |
( |
| ) |
const |
Returns a vector with the complete set of parameters required by the multioutput regression (pseudo-inputs if using FITC, multioutput kernel parameters and inner kernel parameters).
arma::vec gplib::gp_reg_multi::predict |
( |
const std::vector< arma::mat > & |
new_data | ) |
const |
Uses the already trained model to predict output values for new inputs provided in the parameter, this method returns only the mean of the multivariate gaussian distribution resulting from the regression process, which is the "best guess" for each new input.
- Parameters
-
new_data | : A vector of matrices containing points for which output data is unknown in one or more of the output classes. |
Sets the multioutput kernel to be used with the multioutput regression.
This kernel should have already been assigned inner kernels for each latent function.
- Parameters
-
k | : A multioutput class kernel, Default is an LMC Kernel, but you can implement your own class using the provided API. |
void gplib::gp_reg_multi::set_params |
( |
const std::vector< double > & |
params | ) |
|
Sets all the parameters of the multioutput regression using the Vector prvided.
- Parameters
-
params | : A vector containing all parameters required by the multioutput regression (pseudo-inputs if need be, multioutput kernel parameters and inner kernel parameters). |

X, |
|
|
const std::vector< arma::vec > & |
y |
|
) |
| |
Sets the pairs of known input and output data used to train the model.
- Parameters
-
X | : Vector of matrices, each matrix contains the inputs related to each output class. |
y | : Vector of vectors, each vector contains the outputs related to each output class, and to each of the imputs. |

) |
| |
Trains the the model using the FITC approximation, in accordance to the provided training set.
- Parameters
-
num_pi | : Number of inducing points per output class, should be smaller than the smallest number of inputs for any output class, use of this parameter triggers the use of FITC instead of the full regression. |
