#### Summary:
Once the ```stan::model``` class has implemented Hessians and Hessian-vector products, expose them in the ```rstan``` ```modelfit``` class. See https://github.com/stan-dev/stan/issues…

We have a somewhat complicated objective function, of which we need a Hessian matrix. The times to jit the objective function and gradient are pretty fast (about 1 and 5 seconds, respectively) but th…

Is the Gaussian Hessian already mass weighted? For the option `-gh`, there currently isn't any additional mass weighting going on after reading the Hessian from the archive, which may be a big problem…

What are people's thoughts on how constrained optimization should be handled? I ask because I'm writing an implementation of the parametric simplex and affine scaling methods for linear optimization, …

Hi, I am recently studying the principles behind lightGBM. I could not understand the pseudo code about creating histogram on the paper. I will be glad that if somebody can explain it. Is it based on …
