Detailed Description
Extended Kalman Filter with full matrices in fixed point arithmetic.An approximation of the exact Bayesian filter with Gaussian noices and non-linear evolutions of their mean.
Member Function Documentation
| virtual double BM::logpred | ( | const vec & | dt | ) | const [inline, virtual, inherited] |
Evaluates predictive log-likelihood of the given data record I.e. marginal likelihood of the data with the posterior integrated out.
Reimplemented in ARX, MixEF, and multiBM.
Referenced by BM::logpred_m().
