Struct PointerGrad 

pub struct PointerGrad {
    pub w1: Vec<f64>,
    pub w2: Vec<f64>,
    pub v: Vec<f64>,
}

Gradients of the teacher-forced NLL with respect to the attention parameters.

Only the attention head (w1, w2, v) is differentiated here; the encoder parameters are exercised by PointerNetwork::encode but treated as fixed feature extractors for the gradient check.

Fields

w1: Vec<f64>

Gradient w.r.t. w1.

w2: Vec<f64>

Gradient w.r.t. w2.

v: Vec<f64>

Gradient w.r.t. v.
