Mean field方法在许多领域中得到广泛应用,包括: 1.统计物理学:mean field方法用于描述和模拟多体系统中的相变现象,如铁磁相变、气液相变等。 2.社会网络分析:mean field方法用于研究社会网络中的信息传播、群体行为和意见动态等现象。 3.量子力学:mean field方法用于研究量子多体系统中的基态和激发态的性质。 4.生...
结论2:基于Mean Field的变分推断方法主要是假设将隐变量z分成M个相互独立的部分z=(z1,z2,...,zM),当求qj(zj)时固定剩下M-1个部分。 结论3:基于Mean Field的变分推断方法存在的两个问题:(1)假设将z=(z1,z2,...,zM)分成M个相互独立的部分,然后固定其他依次求得qj(zj)。这个假设太强烈,在一些问题...
根据我们上一篇的介绍,mean field (feature learning) regime 用的是1/m,其中m是网络的宽度,而neural tangent kernel (lazy training) regime用的是1/m1/2。两个框架各有优缺点: (1)Mean field 框架 很难刻画网络的泛化结果 (2)NTK 框架 很难分析weight decay以及有很大噪声的情况 一个自然的问题是,有没有...

To find answers to these questions we suggest a novel paradigm of social laser, shortly solaser, which is based on a well-known in quantum physics laser model of coherent amplification of an optical field. The model may be explored to describe real life socially actual information processing ...
A way out for games with many players is to fall back on the game’s mean field version and to derive an approximate equilibrium. The equilibrium of the mean field game here consists of a control and the respective state distribution at the terminal time. Under regularity conditions on the ...

In particular, it reveals explicitly the non-uniqueness of solutions which is widely discussed in the general mean-field-game theory. On the other hand, we hope this example can serve as a natural toy model to analyze the link between stationary and dynamic models, again an important non-...
平均场博弈论(Mean-Field Games)研究的是大量对象之间的博弈,探索在一个竞争的环境中,对象如何选择最优的决策。例如股市里大量根据其他用户行为交易股票的股民,海里游动的鱼群,在世界杯现场看足球赛的观众等。目前,平均场博弈论在经济、金融、机器学习等方面都有应用。那什么是平均场呢?平均场的博弈是指在博弈的场...
