args --
kwds --
- fit(training, num_basis=None)[ソース]
Fitting model to training dataset
- パラメータ:
training (physbo.variable) -- dataset for training
num_basis (int) -- the number of basis (default: self.config.predict.num_basis)
- get_post_fcov(training, test, diag=True)[ソース]
Calculating posterior variance-covariance matrix of model
- パラメータ:
training (physbo.variable) -- training dataset. If already trained, the model does not use this.
test (physbo.variable) -- inputs
diag (bool) -- Diagonlization flag in physbo.exact.get_post_fcov function.
- 戻り値の型:
numpy.ndarray
- get_post_fmean(training, test)[ソース]
Calculating posterior mean value of model
- パラメータ:
training (physbo.variable) -- training dataset. If already trained, the model does not use this.
test (physbo.variable) -- inputs
- 戻り値の型:
numpy.ndarray
- get_post_samples(training, test, alpha=1)[ソース]
Drawing samples of mean values of model
- パラメータ:
training (physbo.variable) -- training dataset. If already trained, the model does not use this.
test (physbo.variable) -- inputs (not used)
alpha (float) -- tuning parameter of the covariance by multiplying alpha**2 for np.random.multivariate_normal.
- 戻り値の型:
numpy.ndarray
- get_predict_samples(training, test, N=1)[ソース]
Drawing samples of values of model
- パラメータ:
training (physbo.variable) -- training dataset. If already trained, the model does not use this.
test (physbo.variable) -- inputs
N (int) -- number of samples (default: 1)
- 戻り値の型:
numpy.ndarray (N x len(test))
