A Hitchhiker's Guide to Momentum

Indeed, the aspect of acceleration even for noise-free convex problems is one of the key reasons why momentum works and why it works so well. ... This function is ...

2023年5月1日 — also known as heavy ball or momentum for short, is an optimization method designed to solve unconstrained minimization problems of the form (1) ...

2018年10月31日 — The study shows that momentum “arises principally in optimistic periods because investors underreact to bad news.” Hong et al. (2007) suggest ...

2019年6月22日 — Momentum technique helps us solve this issue of slow convergence. Consider a situation where a ball on a hilly terrain is trying to reach the deepest valley.

2017年4月4日 — This post explains why momentum works in optimization. Nice interactive images are used to this aim. Here you can find another overview of gradient-descent ...

2024年6月27日 — So when two objects interact, Newton's Third Law says they exert equal forces on each other. They also exchange momentum. The Momentum that one ...

2017年9月20日 — It is a concept from physics, an object in motion will have a tendency to keep moving. The measure of resistance to change in motion is called momentum.

2015年8月12日 — Momentum essentially works by increasing the magnitude of gradients in one direction and decreasing those in another, resulting in a more ...
