double | k_ |
This is the so called Tukey loss function which aggressively attempts to suppress large errors.
The loss p(r) for a given residual 'r' is computed as follow:
p(r) = k^2 * (1 - (1 - r / k^2)^3 ) / 2 for abs(r) <= k, p(r) = k^2 / 2 for abs(r) > k.

k | Is a tunning constant for the Tukey Loss function. |

The weight w(r) for a given residual 'r' is computed as follow: p(r) = (1 - (r / k)^2 )^2 for abs(r) <= k, p(r) = 0.0 for abs(r) > k. Where k Is the scaling paramter of the loss function.
residual | Residual value obtained during the optimization step. |
