Visualization of the COVID-19 infection rates
Mar 14, 2020 in pandemic visualization
COVID-19/coronavirus 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.
This post will be updated frequently (hopefully daily).

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.

Launching tasks from workers with Dask
Jan 4, 2018 in distributed systems dask
Dask recently surprised me with it’s flexibility in a recent use case, even more than the basic use detailed in a previous post. I’ll walk through my use case and the interesting problem it highlights. I’ll show a toy solution and point to the relevant parts of the Dask documentation.

PyTorch: fast and simple
Sep 7, 2017 in optimization systems performance library
I recently came across PyTorch, a new technology prime for optimization and machine learning. The docs make it look attractive, so immediately I wondered “how does it compare with NumPy?”
Turns out it’s a pretty nice framework that’s fast and straightforward to use. I’ll detail the speed before talking about ease-of-use.
