| 1 function CPD = set_fields(CPD, varargin) | |
| 2 % SET_PARAMS Set the parameters (fields) for a gaussian_CPD object | |
| 3 % CPD = set_params(CPD, name/value pairs) | |
| 4 % | |
| 5 % The following optional arguments can be specified in the form of name/value pairs: | |
| 6 % | |
| 7 % mean - mu(:,i) is the mean given Q=i | |
| 8 % cov - Sigma(:,:,i) is the covariance given Q=i | |
| 9 % weights - W(:,:,i) is the regression matrix given Q=i | |
| 10 % cov_type - if 'diag', Sigma(:,:,i) is diagonal | |
| 11 % tied_cov - if 1, we constrain Sigma(:,:,i) to be the same for all i | |
| 12 % clamp_mean - if 1, we do not adjust mu(:,i) during learning | |
| 13 % clamp_cov - if 1, we do not adjust Sigma(:,:,i) during learning | |
| 14 % clamp_weights - if 1, we do not adjust W(:,:,i) during learning | |
| 15 % clamp - if 1, we do not adjust any params | |
| 16 % cov_prior_weight - weight given to I prior for estimating Sigma | |
| 17 % cov_prior_entropic - if 1, we also use an entropic prior for Sigma [0] | |
| 18 % | |
| 19 % e.g., CPD = set_params(CPD, 'mean', [0;0]) | |
