To run this year please fill out the election form by November 29th, 2018.

Articles, Tutorials and Talks

Scikit-learn is a free machine learning library for Python. It features various algorithms like support vector machine, random forests, and k-neighbours, and it also supports Python numerical and scientific libraries like NumPy and SciPy. In this tutorial we will learn how to easily apply Machine Learning with the help of the scikit-learn library.

In this tutorial you will learn how to use Mask R-CNN with Deep Learning, OpenCV, and Python to predict pixel-wise masks for every object in an image.

If you’re not the sort of person who closely follows the internals of Django’s development, you might not know there’s a draft proposal to drastically change the project’s governance. It’s been getting discussion on GitHub and mailing lists, but I want to take some time today to walk through and explain what this proposal does and what problems it’s trying to solve. So. Let’s dive in.

Machine learning is an important topic in lots of industries right now. It’s a fast moving field with lots of active research and receives huge amounts of media attention. This post isn’t intended to be an introduction to machine learning, or a comprehensive overview of the state of the art. Instead it will show how models built using machine learning can be leveraged from within Excel.

This article describes how to create a repeatable process for analyzing data with Jupyter Notebooks.

This is a tutorial style post that walks through using the RPython translation toolchain to create a REPL that executes basic math expressions.

An exploration of NFL play-by-play statistics with Bokeh and Pandas.

This article describes a style of coding in Python that permits easy mixing of synchronous and asynchronous code. As part of the control software for large microwave telescopes (including the South Pole Telescope), we have been using this style of code under a Tornado / Python 2.x stack with success.

Probabilistic programming with Pyro and conclusive proof that Poland was robbed at the 2018 Chess Olympiad.

Tutorial using Python library LightGBM with code samples.

Or: the mystical art of turning a list of D&D spells into a much longer list of much weirder spells.

This article is a follow-up on another one where I built a web scraper to look for houses for sale in Lisbon. This time, I will focus on the transformation and cleaning process of the dataset we gathered before. I will then attempt to perform some exploratory data analysis (EDA) on the dataset. My goal is to give you some examples of what can be done, and not to provide a super complex analysis.

MySQL Shell 8.0.13 (GA) introduced a new feature to allow you to easily import JSON documents to MySQL. The basics of this new feature were described in a previous blog post. In this blog we we will provide more details about this feature, focusing on a practical use case of interest for to many: How to import JSON data from MongoDB to MySQL. The same “recipe” may be applied to import of data from other document-store databases to MySQL, as long as they are able to produce or export data to JSON.
