physbo.blm.lik.linear module

class physbo.blm.lik.linear.linear(basis, params=None, bias=None)

basis

basis for random feature map

nbasis

number of basis

Type:int

bias

params

_init_params

initial value of the parameter

get_mean(X, Psi=None, params=None, bias=None)

calculate mean values

パラメータ:

• X (numpy.ndarray) -- input as an N-by-d matrix
• Psi (numpy.ndarray) -- feature maps Psi(X) as an N-by-l matrix (default: self.get_basis(X))
• params (numpy.ndarray) -- weight as a vector with size l (default: self.params)
• bias (float) -- (default: self.bias)

戻り値:

Psi * params + bias

戻り値の型:

numpy.ndarray

set_bias(bias)

set bias

パラメータ:bias (float) --

set_params(params)

set parameters

パラメータ:params (np.ndarray) --
