Last week I had a chance to visit USC's LONI: Laboratory of Neuro Imaging. Thanks to Farshid Sepehrband (@fsepehrband) for the invite and tour! The best part for me about doing data skeptic is when I have opportunities to visit fantastic companies and labs doing really interesting w... View More >

I had a listener named Scott write in after listening to our episode called The Library Problem and ask an interesting question. In this episode, I explained how using machine learning to predict whether or not a book would be returned has an imbalanced dataset. The vast majority of transactions at the library are "good" ones, meaning the patron brings the book back. Worse, the truly interesting class you'd like to predict and avoid (i.e. books that won't be returned) has the minority of examples in your training ... View More >

Using Git as a CMS

by Kyle Polich

When we rebuilt dataskeptic.com one of our main focuses was setting a foundation to make blogging about data science easy both internally and for guest bloggers as well. It must be easy to publish both Jupyter notebooks and knitr's output. Latex has to work well, and figures should be managed seamlessly. We eventually want to enable interactive plots without headache to the writer, and other more advanced featu... View More >

When we relaunched dataskeptic.com and I started blogging more regularly, I hadn't predicted the influx in traffic to the site that would result almost immediately. I'm doing my best to post useful content regularly, but that's a hard pace to k... View More >

Using Pothole Data

by Kyle Polich

Earlier in 2016, we did an episode about the data of potholes. After Linhda had a pothole related biking accident, we reported the issue to 311 and later went in to the LA City Data Portal's 311 dataset to see how our incident was described in their reco... View More >

Sponsors in 2017

Since starting Data Skeptic in 2014, I've had a number of businesses approach me to do some advertising on the podcast. I've had a blanket "no ads" policy regardless of who came knocking. It's not that I'm ungrateful or have some objection to the show bringing in revenue. I simply didn't want to have to worry about any hassle. I wanted to focus every minute I could dedicate to Data Skeptic to the show's cont... View More >

I'm aware that many listeners first found Data Skeptic due to the bold appeal I made in the first episode of 2016 where I proposed we kill the word cloud. I feel just as strongly today that the word cloud is a useless and ill-informed data visualization. I'm repeatedly grateful to see people on social media mention they're trying a different approach, and in a few cases, appologizing in advance for publishing a word cloud due to peer pressure. Stay strong, friends! Together, we can end worthlessly uninformative data visualizati... View More >

In case you don't already know, Latex is a markup language that allows people to create beautifully typset documents using mathematical and scientific symbols and notiation. It's an absolute necessity in technical writing. There's a small learning curve, but once you get used to Latex, it's pretty easy to write. Since back in grad school, I was used to writing Latex documents and using the available tools to render them to P... View More >
