Workflow

Create a new post as follows:

$ hugo new posts/YYYY-MM-DD-title-slug.md

This will create a new file in content/posts using the archetypes/posts.md archetype. The archetype ensures that the title is correctly extracted from the post path name without the date components as well as the slug. You can then open the file and start editing.

To view the rendered version of the site:

$ hugo serve -D

Note that the -D flag builds drafts and enables you to work on posts before they're published.

Images should be added to the static/images folder using a path in the form of YYYY-MM-DD-image-name.png -- this is a throwback to the old Jekyll site, and I'd prefer to use content bundles, but we haven't quite made that transition yet. Embed images into markdown posts using the standard markdown with a link from the absolute images directory, e.g. /images/YYYY-MM-DD-image-name.png from the example above.

To deploy, simply push to the main branch and GitHub Actions will deploy the contents of the public directory to GitHub pages. For manual deployment, use the bin/publish.sh script.

About

This page is primarily my development journal and really only contains notes and ramblings for me to refer to as I practice programming. Please feel free to read and use anything you find on this site, but note it is not meant for publication or wide public consumption. If you want to find my more formal writing, check out the Rotational Labs Blog where I write about Golang, distributed systems, Python, data science, streaming, and more.

Name Origin

A libellus (plural libelli) was a document given to a Roman citizen to certify performance of a pagan sacrifice, hence demonstrating loyalty to the authorities of the Roman Empire. They could also mean certificates of indulgence, in which the confessors or martyrs interceded for apostate Christians. —Wikipedia

So these notes certify the performance of my programming, demonstrating my loyalty to Open Source development, as well as a confession of my programming sins.

Thanks

This site was built with Hugo using the PaperMod theme by Aditya Telange. It is hosted on GitHub and served with GitHub Pages. The logo and icon I've used is Bear by Gregor Cresnar from the Noun Project.

Page resources missing for topic Text classification using NLTK

Hello,
All the page styling resources like css, fonts, images are missing (returning 404) due to which the page is not rendering as it should. The following is the page link http://bbengfort.github.io/tutorials/2016/05/19/text-classification-nltk-sckit-learn.html

Pattern Recognition with Nearest Neighbors

This post is the first in a series that discusses the machine learning methods that I will present in the Georgetown data analytics course. My hope is that I can expose through some tricky JavaScript/visualization the mechanism behind the learning as well as provide some description. These posts will go on DDL's blog.

For kNN the idea is to provide a visualization, that allows you to slide the k parameter to change the model. See Understanding the Bias Variance Trade-Off for something very similar. I will also provide accuracy metrics, as well as possibly a ROC curve or something similar. This will hopefully better allow students to understand how kNN works in practice.
