class Factor(domain, values)

Bases: object

static active(domain, structural_zeros)

create a factor that is 0 everywhere except in positions present in

‘structural_zeros’, where it is -infinity

Param

domain: the domain of this factor

Param

structural_zeros: a list of values that are not possible

condition(evidence)

evidence is a dictionary where keys are attributes, and values are elements of the domain for that attribute

copy(out=None)

datavector(flatten=True)

Materialize the data vector

exp(out=None)

expand(domain)

log(out=None)

logaddexp(other)

logsumexp(attrs=None)

max(attrs=None)

static ones(domain)

project(attrs, agg='sum')

project the factor onto a list of attributes (in order) using either sum or logsumexp to aggregate along other attributes

static random(domain)

sum(attrs=None)

transpose(attrs)

static uniform(domain)

static zeros(domain)
