Chapter 11.05: Log-cosh loss

[leofhp]

Chapter 11.05, slide 3, log-cosh loss:
"Approximately equal to 0.5(|y − f (x)|)2 for small x and to |y − f (x)| − log 2 for large x" should instead be "Approximately equal to 0.5(|y − f (x)|)2 for small |y - f(x)| and to |y − f (x)| − log 2 for large |y - f(x)|" and accordingly the axis labels of the plot should be y - f(x) and L(y, f(x)).
