Length scale in Kernel functions
显示 更早的评论
Hello all,
I am new to machine learning and I have a question regarding ARD Matern 5/2 kernel functions used in Bayesopt.
How is characteristic length scale calculated in? Is it a constnat value or it varies in each iteration? Any useful refenrece?
The documentation is not very clear to me and any helps is greatly appreciated.

"The characteristic length scales briefly define how far apart the input values 
can be for the response values to become uncorrelated. "
can be for the response values to become uncorrelated. "Refer to the following documentation for more information on characteristic length scale:
Hope it helps!
