Note

Some changes were made as compared to the original paper.

• Learning rate was kept to 1e-3 instead of 1e-4.
• Also, in the paper, equation for the curves is given as: LEn(x) = LEn−1(x) + αnLEn−1(x)(1 − LEn−1(x)) , whereas in the author's original implementation, the curve equation is taken as: LEn(x) = LEn−1(x) + αnLEn−1(x)(LEn−1(x) - 1)
