RewardSignal

tokio_prompt_orchestrator::feedback_loop

Struct RewardSignal 

Source 
pub struct RewardSignal {
    pub quality_score: f64,
    pub cost_penalty: f64,
    pub latency_penalty: f64,
    pub reward: f64,
}
Expand description

Composite reward derived from a single Feedback record.

Formula: quality_score * 0.5 - cost_penalty * 0.3 - latency_penalty * 0.2

Fields§

§quality_score: f64

Raw quality score in [0, 1] (equal to feedback.rating).

§cost_penalty: f64

Normalised cost penalty proportional to tokens used (range [0, 1]).

§latency_penalty: f64

Normalised latency penalty (range [0, 1]).

§reward: f64

Final composite reward value.

Implementations§

Source§

impl RewardSignal

Source

pub fn from_feedback( feedback: &Feedback, max_tokens: u64, max_latency_ms: u64, ) -> Self

Compute a RewardSignal from a raw Feedback record.

max_tokens and max_latency_ms are used to normalise the penalties into [0, 1]. If either is zero the corresponding penalty is 0.
