Struct ValueNetwork 

pub struct ValueNetwork { /* private fields */ }

Simple value network for state value estimation

Implementations

impl ValueNetwork

pub fn new(input_size: usize, hidden_size: usize) -> Self

Create a new value network

pub fn estimate(&mut self, state: &[f64]) -> f64

Estimate value of a state

pub fn estimate_previous(&self) -> f64

Get previous estimate

pub fn update(&mut self, state: &[f64], td_error: f64, lr: f64)

Update weights with TD error using proper backpropagation

Implements gradient descent with:

• Forward pass to compute activations
• Backward pass to compute ∂V/∂w
• Weight update: w += lr * td_error * ∂V/∂w

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueNetwork

fn fmt(&self, f: &mut Formatter<'_>) -> Result
