Struct PgdAttack 

pub struct PgdAttack {
    pub steps: u32,
    pub step_size: f32,
    pub epsilon: f32,
}

PGD attack implementation

Projected Gradient Descent attack with multiple iterations.

Fields

steps: u32

Number of iterations

step_size: f32

Step size per iteration

epsilon: f32

Maximum perturbation (L-infinity bound)

Implementations

impl PgdAttack

pub const fn new(steps: u32, step_size: f32, epsilon: f32) -> PgdAttack

Create a new PGD attack

pub fn attack<F>(&self, input: &[f32], gradient_fn: F) -> Vec<f32>

where F: FnMut(&[f32]) -> Vec<f32>,

Run full PGD attack

Arguments

• input - Original input vector
• gradient_fn - Function that computes gradient at current point

Returns

Adversarial example after all steps
