Method Detail

getInflectionPoint

public double getInflectionPoint()

The inflection point of the sigmoid used as a shrinking factor. For a given category, if the sample size is greater than this value, then the posterior weight is greater than the prior.

Returns:

the inflection point of the sigmoid function.

getSmoothing

public double getSmoothing()

The smoothing factor, i.e. the inverse of the slope of the sigmoid at the inflection point. When it tends to 0, the sigmoid becomes a step function.

Returns:

the smoothing factor of the sigmoid function.
