In the answer to "what is the Hessian" at this site:
the person answering the question concludes by saying
"Fun fact, adding the momentum term to your gradient based optimization is (under sufficient conditions) approximating the hessian based optimization (and is far less computationally expensive)."
I have tried to understand this point and look online but am not sure what is meant by the momentum approximating hessian based optimization. How is momentum like hessian based optimization?
