## 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...

Matlab finally embraces (partially) the way matrix manipulation should be Starting in MATLAB R2016b with the addition of implicit expansion, some combinatio...

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...

I created an introductory machine learning class for math undergrad who has no previous exposure to programming back in Winter 2019 quarter. This post will t...

这个简明教程主要是教大家使用强大的LaTeX宏包TikZ来绘制工作生活中需要的一些示意图。

A general question is as follows:

Since Google+ is finally to be shut down by Google as of Feb 1, 2019, aside from migrating G+’s social bookmarking functionality to Medium.com and Pocket app...

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...
