Description of the problem Gil Kalai asks the following problem: given a random tree on nn vertices asymptotically behaves like nn vertices by generating n=2n=2 to  Read more
Getting Started with Predictive Maintenance Models
This was originally posted on the Silicon Valley Data Science blog. In a previous post, we introduced an example of an IoT predictive maintenance problem. We framed the problem as one of estimating the remaining useful life (RUL) of in-service equipment, given some past operational history and historical run-to-failure data. Reading that... Read more

Descriptive Analysis of MLST Data for MRSA
During one of my summers, I had the opportunity to conduct some research on the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in vulnerable populations and examining US emergency department data and I thought this would be a pretty interesting topic to expand on for my thesis in light of the increasing concerns...

What Makes a Good Data Visualization – a Data Scientist perspective
Data visualization has been a subject of many thousands of books, courses, and blogs. My course on data mining included a one-hour lecture on Data Visualization. However, since you, my reader, don’t have an hour to read this blog, here is a KDnuggets-sized summary of what makes a good data visualization... Read more
Exploratory Data Analysis of Tropical Storms in R
Exploratory Data Analysis of Tropical Storms in R The disastrous impact of recent hurricanes, Harvey and Irma, generated a large influx of data within the online community. I was curious about the history of hurricanes and tropical storms so I found a data set on data.world and started some basic Exploratory... Read more
Are Your Predictive Models like Broken Clocks?
A wise philosopher (or comedian) once said, “Even a broken clock is right twice a day.” That same statement might also apply to some predictive models. Since prediction is about the future (usually), then random chance (like broken clockwork) may allow our model to be right occasionally (just by accident). The... Read more
Catching up with Ryan Compton, Head of Applied Machine Learning at Clarifai
Okay. So, give us a little preview of the talk and the sort of the topics you’re hitting. Basically what it is, is over the course of the past twenty or thirty years, we’ve been having these problems where you have a computer, it’s connected to a network, suddenly... Read more
