Trait Implementations

impl Backend for CpuBackend

fn add(a: &Tensor, b: &Tensor) -> EtensorResult<Tensor>

Executes an element-wise addition (a + b) and returns a dynamically allocated output tensor.

fn mul(a: &Tensor, b: &Tensor) -> EtensorResult<Tensor>

Executes an element-wise multiplication (a * b) and returns a dynamically allocated output tensor.

fn matmul(a: &Tensor, b: &Tensor) -> EtensorResult<Tensor>

Executes matrix multiplication (a @ b) and returns a dynamically allocated output tensor.

fn sum_all(a: &Tensor) -> EtensorResult<Tensor>

Executes a global sum reduction, collapsing the tensor into a single scalar.

fn mean_all(a: &Tensor) -> EtensorResult<Tensor>

Executes a global mean reduction, collapsing the tensor into a single scalar.

fn max_all(a: &Tensor) -> EtensorResult<Tensor>

Executes a global max reduction, collapsing the tensor into a single scalar.

fn relu(a: &Tensor) -> EtensorResult<Tensor>

Executes the Rectified Linear Unit (ReLU) activation function.

fn sigmoid(a: &Tensor) -> EtensorResult<Tensor>

Executes the Sigmoid activation function.

fn add_relu(a: &Tensor, b: &Tensor) -> EtensorResult<Tensor>

Executes Fused Addition and ReLU: f(A, B) = max(0, A + B)

fn linear(x: &Tensor, w: &Tensor, b: &Tensor) -> EtensorResult<Tensor>

Executes Fused Linear Layer: y = X @ W + b
