Laplace(拉普拉斯)先验与L1正则化 在之前的一篇博客中L1正则化及其推导推导证明了L1正则化是如何使参数稀疏化人,并且提到过L1正则化如果从贝叶斯的观点看来是Laplace先验,事实上如果从贝叶斯的观点,所有的正则化都是来自于对参数分布的先验。现在来看一下为什么Laplace先验会导出L1正则化,也顺便证明Gauss(高斯)先验会导出...
他提出拉普拉斯变换(Laplace Transform) 的目的是想要解决他当时研究的牛顿引力场和太阳系的问题中涉及的积分微分方程。拉普拉斯变换其实是一个数学上的简便算法;想要了解其”物理”意义 — 如果有的话 — 请看我举这样一个例子:问题:请计算十万乘以一千万。对于没学过指数的人,就只会直接相乘;对于学过指数的人,...

using Laplace Transform tables. Homework Equations I know the basic convolution theorem is (f*g)(t) = ∫f(τ)g(t-τ)dτ The Attempt at a Solution I'm not sure if this is double convolution or if I'm missing an easy substitution. 1. What are ##f(t)## and ##g(t)## in ...
