Struct Var 

pub struct Var(/* private fields */);

Implementations

impl Var

pub fn leaf(t: Tensor) -> Var

A differentiable leaf (a parameter or input we want gradients for).

pub fn value(&self) -> &Tensor

pub fn grad(&self) -> Option<Tensor>

pub fn backward(&self)

Backpropagate from this (scalar-ish) output: seed grad = ones, walk reverse-topo.

pub fn add(&self, o: &Var) -> Var

pub fn sub(&self, o: &Var) -> Var

pub fn mul(&self, o: &Var) -> Var

pub fn matmul(&self, o: &Var) -> Var

Matmul (last two dims; equal or absent batch dims).

pub fn relu(&self) -> Var

pub fn sum_all(&self) -> Var

pub fn mean_all(&self) -> Var

Trait Implementations

impl Clone for Var

fn clone(&self) -> Var

Returns a duplicate of the value.

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

Performs copy-assignment from source.
