Method Summary

Modifier and Type	Method	Description
static TrustUpdateStrategy	bayesian()	Bayesian update strategy.
static TrustUpdateStrategy	ema(double alpha)	Exponential Moving Average strategy.
double	update(double currentScore, Outcome outcome, double quality, int totalInteractions)	Calculates the new trust score.
static TrustUpdateStrategy	weightedAverage()	Simple weighted average strategy.

Method Details

update

double update(double currentScore,
 Outcome outcome,
 double quality,
 int totalInteractions)

Calculates the new trust score.

Parameters:

currentScore - current trust score (0.0 - 1.0)

outcome - the interaction outcome

quality - quality of the outcome (0.0 - 1.0)

totalInteractions - total number of interactions so far

Returns:

new trust score (will be clamped to 0.0 - 1.0)

ema

static TrustUpdateStrategy ema(double alpha)

Exponential Moving Average strategy. More recent interactions have greater weight.

Parameters:

alpha - smoothing factor (0.0 - 1.0, higher = more weight on recent)

bayesian

static TrustUpdateStrategy bayesian()

Bayesian update strategy. Uses beta distribution model (successes / total).

weightedAverage

static TrustUpdateStrategy weightedAverage()

Simple weighted average strategy.
