Strategy
You have an idea that you need to be in the data game. But you don’t have any clue on where to start. What should I collect? What is important? How can I even use data to impact the bottom […]

Insights are great. But what you really want is action. Once you have a data science model created, you want to see it out in the wild. Then deploy your model with us. When you choose to deploy your model […]
Read MoreHow to Hire My First Data Scientist
Usually, I write a tutorial for other data scientists, or individuals that want to become data scientists. Today, I wanted to write a tutorial for managers that have never hired a data scientist before. Hopefully, my data scientist friends will […]
Reverse Image Lookup Out Of The Box
What is a reverse image search? It is where you give me an image and I find a bunch of images that look like the one that you gave me. So, I thought that I would give that a quick […]
Learning About Fashion With A Convolutional Neural Network
So for the past week or so I have been working on a model, a convolutional neural network to participate in a kaggle competition. I have been developing it on google’s colab project. See my last post to get an […]
I Fell In Love With Google Colab
So forgive my kind of sporadic posting, I’ve been trying to keep to at least a biweekly schedule since I am living with a newborn. The whole new baby thing makes writing posts for this blog really tough. So since […]
March Madness Predicted Upsets 2018
If you have read my blog since last year you know that back in August I put together my ideas for an algorithm which would predict the outcome of the March Madness tournament. Well, Selection Sunday came this week and […]
Fourier Transforms, Fraud, and Fun
I recently backwards engineered the algorithm that some unsavory characters were using to brute force find real credit card numbers and fraudulently charge them. The backbone to reverse engineering their algorithm was the Fourier Transform. I think that this is […]
Box-Cox Transforms and Other Nonparametric Normalization Methods
So that is a bit of a snarky title. Today, I want to talk about techniques that you can use to transform non-normal data into a distribution that makes way more sense. This can be useful for all kinds of […]
Publishing a Bokeh App to Heroku
This is the last of three posts. In the first post we did some really fun Bayesian modeling. Specifically, we built a longitudinal or panel data model using a Bayesian model with fixed effects for states and time. And what […]
Christmas Give Away Winner
My first order of business is to announce the winner of my Christmas giveaway. This past Christmas, I was running a giveaway for some free time to spend with me for some data science coaching and a fifty dollar gift […]
Creating an Interactive Visualization With Bokeh
Last post, I created a model that would predict what effect changing the taxes on cigarettes would have on health care expenditures. That model was fun to build, but it is difficult to get a feel for what is going […]
