Building a single-GPU budget machine learning rig part I: random tidbits
Prologue As is known, MATLAB is notoriously slow in executing for loops. Looping through a large array is usually a nightmare, even more so if you add if/the...
This notes contains some of the notes I used in UC Irvine Math 130C course.
I finally decided to migrate various of my old writing in my faculty website at UC Irvine locally to Jekyll. Apparently it has a much more flexible and pleas...
本文前半部分是介绍Kaggle的机器学习比赛，后半则是记录今年3月到6月带领几位University of California, Irvine数学系本科生参加由美国洛斯阿拉莫斯国家实验室在Kaggle上组织的地震预测比赛。
In the course project, groups of three students will work together to create regression/classifiers for an in-class Kaggle prediction competition. The compet...
A general question is as follows:
这是很久以前在果壳小组写的外行解读帖子，现在果壳小组没有了，把自己以前给果壳写的帖子留个备份。
This is a continuation of my previous “complaining” post on the language difference of mathematician vs physicists regarding the same thing.
I took a quantum physics class on Coursera this year and I found that the Mathematical language spoken by the two communities, math vs physics, are quite dif...
This is an exercise for finite element method most likely. Our question is:
First about the appropriate boundary condition we would like to impose: The cross product(scalar-$\mathrm{curl}$) in $\mathbb{R}^2$ is done by we embed a vec...
Sobolev embedding When $p=n$
