Struct ThroughputRegressor 

pub struct ThroughputRegressor { /* private fields */ }

Simple linear regression model for throughput prediction.

Uses closed-form solution: w = (X^T X)^-1 X^T y With ml-tuner feature: uses aprender::RandomForestRegressor (SHOWCASE-BRICK-001)

Implementations

impl ThroughputRegressor

pub fn new() -> Self

Create a new regressor with default weights

pub fn with_random_forest(n_estimators: usize) -> Self

Create a new regressor using aprender RandomForest (ml-tuner feature)

pub fn train(&mut self, data: &[(TunerFeatures, f32)]) -> Result<(), TunerError>

Train the model on labeled data

pub fn train_random_forest( &mut self, data: &[(TunerFeatures, f32)], ) -> Result<(), TunerError>

Train using aprender RandomForest (ml-tuner feature)

Provides superior throughput prediction via ensemble learning. See: SHOWCASE-BRICK-001 Section 12.3

pub fn predict(&self, features: &TunerFeatures) -> ThroughputPrediction

Predict throughput for features

With ml-tuner feature: uses trained RandomForest if available. Falls back to linear model otherwise.

pub fn compute_roofline_bound(features: &TunerFeatures) -> f32

Compute theoretical maximum throughput based on roofline model (v1.1.0)

For memory-bound LLM inference (decode phase): max_tps = memory_bw_bytes_per_sec / bytes_per_token bytes_per_token = model_params x bytes_per_param / batch_size

pub fn bytes_per_param_from_onehot(onehot: &[f32; 8]) -> f32

Extract bytes per param from quant type one-hot encoding
