• Learning Python for data science

  Sep 12, 2021 in python data science

  Are you a scientist that has some experience with programming language, but not much? Are you looking to get into the “data science” space, and have gotten some recommendations about “Python” and “Pandas” from friends?

  If so, this guide is for you. This guide will teach how to explore a dataset quickly and efficiently. Here’s a demo of what I mean:

• COVID-19, age and lockdowns

  Aug 9, 2020 in pandemic visualization

  I wrote “Visualization of the COVID-19 infection rates” with two goals: to warn people about the upcoming pandemic and to provide insight into that pandemic.

  The US took precautions within a couple months, and the length and intensity of the precautions has surprised me. Even four months later, individuals generally believe they should take actions to limit the spread of COVID-19. This includes wearing a mask and working remotely if possible.

  But are these precautions justified? There’s no harm done if everyone gets an benign virus. Do the data justify mandating wearing masks and closing schools? Let’s look.

• Visualization of the COVID-19 infection rates

  Mar 14, 2020 in pandemic visualization

  The Wuhan virus/COVID-19 is spreading through the world. The WHO classifies it as a pandemic (source), and the United States has declared a national emergency because of it (source).

  Data on the infection rate is difficult to find. This post will present some data sources and show some visualizations of the infections. It’ll also provide some tips on how to avoid coronavirus.

• Better and faster hyperparameter optimization with Dask

  ☆ Sep 27, 2019 in distributed machine-learning dask

  Dask’s machine learning package, Dask-ML now implements Hyperband, an advanced “hyperparameter optimization” algorithm that performs rather well. This post will

  • describe “hyperparameter optimization”, a common problem in machine learning
  • describe Hyperband’s benefits and why it works
  • show how to use Hyperband via example alongside performance comparisons

  In this post, I’ll walk through a practical example and highlight key portions of the paper “Better and faster hyperparameter optimization with Dask”, which is also summarized in a ~25 minute SciPy 2019 talk.
