afe.driver.statistic

Analysis of statistics on tensors.

Classes

`StatisticInstance`	A collector of statistics on a stream of inputs.
`Statistic`	A method of computing a property over a stream of inputs.

Module Contents

class afe.driver.statistic.StatisticInstance

A collector of statistics on a stream of inputs. With an instance of the class, inputs are supplied repeatedly by calling update, then the computed result is read by calling finish.

abstract update(x: _I) → None

abstract finish() → _O

class afe.driver.statistic.Statistic

A method of computing a property over a stream of inputs. The property is normally a reduction, e.g., the average of the mean squared errors of all inputs.

initialize: Callable[[], _S]

update: Callable[[_S, _I], None]

finish: Callable[[_S], _O]

instantiate_type() → Type[StatisticInstance[_I, _O]]

comap(f: Callable[[_A], _I]) → Statistic[_A, _O]

Map a function over the input stream.

Parameters:: f – Function to apply to inputs
Returns:: Transformed Statistic

map(f: Callable[[_O], _A]) → Statistic[_I, _A]

Map a function over the output.

Parameters:: f – Function to apply to output
Returns:: Transformed Statistic
