physbo.blm.lik.linear module

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

Bases: object

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

Parameters

• 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)

Returns

Psi * params + bias

Return type

numpy.ndarray

set_bias(bias)

set bias

Parameters

bias (float) –

set_params(params)

set parameters

Parameters

params (np.ndarray) –
