Python Multi-Threading vs Multi-Processing

There is a library called threading in Python and it uses threads (rather than just processes) to implement parallelism. This may be surprising news if you know about the Python's Global Interpreter Lock, or GIL, but it actually works well for certain instances without violating the GIL. And this is all done without any overhead -- simply define…

Using Hypothesis Development Canvas to Predict Golden State Warrior Victories

The third annual University of San Francisco (USF) MBA class Golden State Warriors analytics exercise provided an opportunity to test the students’ ability to “Think Like a Data Scientist” with respect to identifying and quantifying variables that might be better predictors of performance for the Golden State Warriors professional basketball team. This was also an opportunity to test and fine-tune the Hypothesis Development Canvas, and boy was that an eye-opener for me. The…

Big Data In Real Estate Industry

A couple of quintillion of bytes are generated every day. Data is all around you. And every day we perceive new data and our brain processes it constantly. But we cannot constantly work with huge data volumes efficiently, that is where special algorithms for processing Big Data come in. Bis Data contributes to many fields of activity, and today it is rapidly being integrated into the real estate sector.…

The Two (Conflicting) Definitions of AI

Summary:  There are two definitions currently in use for AI, the popular definition and the data science definition and they conflict in fundamental ways.  If you’re going to explain or recommend AI to a non-data scientist, it’s important to understand the difference.


For a profession as concerned with accuracy as we are, we do a really poor job at naming things, or at least being consistent in the naming.  “Big Data” – totally misleading…
