In Hawaii for HICSS 50. So far so good. Have seen old friends, met new friends and am enjoying Panoply security competition. Paper being nominated as best paper does not hurt either. Hawaii
Board Games and Miniature Painting
Alright, so far I have been posting about my research and teaching... Now that I have a job that I feel fairly confident about, I think I can actually blog with a bit more liberty. I have been a huge fan of boardgames since I laid my eyes on the "Milyoner" (Turkish knockoff of monopoly).... Continue Reading →
I use AWS to run the various scripts used in data collection. I have been paying about $20 each month for a t1 micro instance since my free tier and academic credits ran out. That is quite a price to pay for 1 core and about 600MB ram. Maybe AWS is not the best option... Continue Reading →
Understanding Neural Networks
A few months ago I made a presentation on Tensor Flow for MBA students. The challenge was to simplify the technical underpinnings of the technology sufficiently while preserving a semblance of what it was good for. One particular challenge was visualizing the technology. Showing python code and output was out of the question and at... Continue Reading →
OpenRefine for Data Mangling
I often use data from various sources and sometimes have to get creative about transforming the data into a format that I can use easily. So far I have done this mainly with R (and with Python from time to time). The other day, Dr. Mazzolla pointed to OpenRefine, an application for data clean-up and... Continue Reading →
Writing Better R Code
When I teach R, I always caution the audiences about the quirks of R programming. It is very typical for someone with a background in Java or Python to write code in R that will take forever to execute (like I used to do, and sometimes still do). I warn the students about loops and... Continue Reading →

Our study aims to uncover the dynamics shaping the online labor markets (freelancer.com, upwork.com, elance.com ...), with a focus on the role of country development level on the IT service providers' ability to survive and earn a...

Google TensorFlow
Google open sourced TensorFlow (TF), a distributed machine learning library, in November. The basic idea is that, you build your ML process into a graph and let TF handle the running and distribution of the work between cores. Be it cores in your CPU or GPU, TF has you covered. The dataflow graph works much... Continue Reading →
IBM Watson Explorer, Predictive Analytics Made Easy?
I am currently developing a tutorial for EMBA students for IBM's Watson Explorer. Having just recently finished content development for R workshop for MSBA, I must say it is a pretty interesting experience. On the one hand you have R, a complex but powerful tool that is designed to lift (almost) any kind of analytics... Continue Reading →
