pub struct ComputationTape { /* private fields */ }

Computational tape for recording operations

Implementations

impl ComputationTape

pub fn new() -> Self

Create a new empty tape

pub fn add_input(&mut self, var: Variable)

Add an input variable to the tape

pub fn add_node(&mut self, node: TapeNode)

Add a computation node to the tape

pub fn backward(&self, gradients: &mut Vec<f64>) -> Result<(), OptimizeError>

Perform backpropagation to compute gradients

pub fn forward(&self, input_values: &[f64]) -> Result<Vec<f64>, OptimizeError>

Forward pass to compute all variable values

pub fn add_constant(&mut self, value: f64) -> usize

Add a constant to the tape
