A Trust-region Framework for Moment Estimation
Article summary
Quick briefing — cleaned from the original RSS feed
arXiv:2608.04026v1 Announce Type: new Abstract: In this paper, we develop a trust-region framework for understanding the behavior of adaptive moment estimation mechanisms, such as \textsc{Adam}, in stochastic gradient optimization. Specifically, in this framework, the magnitude of the update step for each individual weight is constrained within a trust-region governed by a moment constraint of order $p\in[2,4]$. The resulting derivation then leads to a family of learning-rate mechanisms based…
