      sigmoid_ in grad and hess for rank objective (#2322) · aee92f63
      sbruch authored
      * Lambdas and hessians need to factor sigmoid_ into the computation. Additionally, the sigmoid function has an arbitrary factor of 2 in the exponent; it is not just non-standard but the gradients are not computed correctly anyway.
      
      * Update unit test
      
      * Also remove a heuristic that normalizes the gradient by the difference in scores.
      
      * Also fix unit test after removing the heuristic
