Struct AdafactorState

pub struct AdafactorState<const D: usize> {
    pub time: usize,
    pub second_moment: Tensor<D>,
    pub column_second_moment: Option<Tensor<D>>,
}

Expand description

Adafactor state for a single parameter tensor.

Fields§

§time: usize

Number of updates applied to this parameter.

§second_moment: Tensor<D>

Moving average of squared gradients, reduced over the last dimension for matrices and higher-rank tensors (shape [..., rows, 1]). Vectors retain their full shape.

§column_second_moment: Option<Tensor<D>>

Column second moment for matrices and higher-rank tensors (shape [..., 1, columns]). Absent for vectors.
