tensor.tanh

    fn tanh(self: @Tensor<T>) -> Tensor<T>;

Computes the hyperbolic tangent of all elements of the input tensor. $$ y_i=tanh({x_i}) $$

Args

  • self(@Tensor<T>) - The input tensor.

Returns

Returns a new tensor in T with the hyperbolic tangent of the elements of the input tensor.

Type Constraints

Constrain input and output types to fixed point tensors.

Examples

use core::array::{ArrayTrait, SpanTrait};

use orion::operators::tensor::{TensorTrait, Tensor, FP8x23Tensor};
use orion::numbers::{FixedTrait, FP8x23};

fn tanh_example() -> Tensor<FP8x23> {
    let tensor = TensorTrait::<FP8x23>::new(
        shape: array![2, 2].span(),
        data: array![
            FixedTrait::new_unscaled(0, false),
            FixedTrait::new_unscaled(1, false),
            FixedTrait::new_unscaled(2, false),
            FixedTrait::new_unscaled(3, false)
        ]
            .span(),
    );

    return tensor.tanh();
