Machine Learning Interview Prep -- ML Fundamentals

This is a series of notes that I prepared during my job seeking in the last few months and there will be four separate notes in total:

  • Fundamentals of Machine Learning (This note)
  • Fundamentals of Deep Learning
  • Machine Learning Models
  • Derivation, Implementation & Experience

This note will cover some very basic concepts of machine learning and will focus on the application, instead of the theory.

Coursera offers free certificate for a limited time during COVID-19 pandemic

Recently, I didn’t update my notes as frequently as before. One of the reasons is that I’m very busy with my work since I’m about to start my intern. Another important reason is that I’ve been spending lots of time in taking courses with free certificates on Coursera. As one of the biggest MOOC, Coursera offers many free courses covering a variety of subjects. However, free audit options cannot earn us a certificate even if you follow the instruction and complete all required assignment. If you want the certificate as a proof of your hard work, you have to pay another 50 bucks (the fees vary depending on the course). Now, due to the pandemic situation, more and more people are forced to study and work from home. Coursera also offers free certificate for over 100 courses.

A full list of these coursers can be found here. You may register these courses for free until 7/31/2020.

Happy learning and stay healthy!

Grover Search as a Naturally Occurring Phenomenon

A few days ago, when I was browsing papers recently accepted by Phys. Rev. Lett. I noticed an interesting article Grover Search as a Naturally Occurring Phenomenon, which has just been published online today. I found this work really very fascinating, so I write this short note describing the work.

AlphaZero explores global optimization of quantum dynamics in superconducting circuit QED

AlphaZero explores global optimization of quantum dynamics in superconducting circuit QED

I’ve been thinking about a class of optimization problems on a quantum computer and wish to explore them with machine learning algorithms, especially reinforcement learning, as it does not require a good initial guess (radom, intuition or whatever). More recently, I came across to the paper “Global optimization of quantum dynamics with AlphaZero deep exploration”, which has been published online about 2 weeks ago. While the authors considered a rather ideal situation, their work did shed lights on my research. So, I prepare this note to briefly discuss their work and some relevant topics.

Building personal blog with GitHub Pages, Jekyll and AMP (Outdated)

Updated on 04/16/2023: This post is outdated and this blog no longer used Jekyll and AMP.

I built this Blog with Jekyll, GitHub Pages and AMP (see links at footer). The basic framework is based upon template hanuman, yet significant modifications are made. In this note, I share the basics of using these tools to build and customize your own website. This note is very friendly for starters.
