Onboarding as a Machine Learning Engineer

It’s been 3 months since I started my new position as a Machine Learning Engineer (MLE) at Spotify. What I like most about this position is that I get to participate in building an end-to-end pipeline, including ideation and experiment, data engineering, machine learning modeling, model serving, online A/B test, monitoring, and many more.

Tips for first-time mentors from a first-time mentor

This summer, I volunteered to be a mentor for a data science intern. It reminds me of my own internship 2 years ago, when I learned so much from my mentor (see my previous posts). Being a mentor not only allows me to view a summer internship from the other side of the table, but also presents new challenges and learning opportunities for myself. In this post, I will share some tips for first-time mentors from my experience as a first-time mentor.

Reinforcement learning (I): overview

In the past 2 years, I have been following progress in Reinforcement Learning (RL). RL beats human experts in Go [1], and achieves professional levels in Dota2 [2] and StarCraft [3]. RL is being mentioned more and more often in mainstream media and conferences. 

I think it is a good time for me to revisit RL. (more…)

How to nail a presentation

Now that we have done most of the hard work: numerous experiments, survey, coding, refactoring, pipelining, analysis, visualization, charts, numbers, written documents and so on, we are going to give a final presentation. “That’s easy,” one may think, “Just paste my results into PowerPoint slides and click through it.”

Having seen quite a lot of presentations at conferences, group meetings, and tech demos, and having given many presentations myself in different scenarios, one thing I can say for sure about presentations is that “It is not easy” at all. It is as demanding as most of the hard work we have done, and requires similar learning and practice as coding, analysis, and writing. In this post, I will summarize what I learned from my mentors, teachers, peers, as well as my own mistakes about presentations.

My favorite talks at ICML 2019

industry

Last month, I went to Long Beach, California to attend the 36th international conference machine learning (ICML). Having been to several academic conferences during graduate school in neuroscience (SfN) and biophysics (BPS), I was very excited to go to a comprehensive machine learning conference for the first time. Here are my key takeaways and favorite talks at ICML 2019.
