Fortran Neural Network Code


module neural_network
    implicit none
    real(8), allocatable :: weights(:), biases(:)
    contains

    subroutine train_network(inputs, outputs)
        real(8), dimension(:,:), intent(in) :: inputs
        real(8), dimension(:,:), intent(in) :: outputs
        real(8), dimension(size(inputs,1)) :: predictions

        !\$omp parallel do
        do i = 1, size(inputs,1)
            predictions(i) = matmul(weights, inputs(i,:)) + biases
        end do
        !\$omp end parallel do

        ! Update weights using gradient descent
        weights = weights - learning_rate * gradient
    end subroutine train_network
end module neural_network
