Data Science: Do We Really Need Math?

It is sometimes said that you don't need to know math to be a data scientist. Sometimes the opposite is said, after all, data science is supposed to be a science! Regardless, below are a few of my articles featuring how data science and math can benefit from each other - not just math to solve data science problems, but also data science to solve math problems.

How Can Companies Get The Most Value Out Of Their Data

Having spent the better part of the last decade helping organisations in the U.S. and the U.K. use data to drive profit, efficiency, and performance improvements, I thought it would be helpful to jot down best practices for organizations that are looking to get the most value out of their enterprise-level financial and operational data sets.

Every organisation entering the roaring 20s knows that they must use their data as a strategic differentiator to gain a competitive advantage and…

Why the Concept of “Citizen Data Scientist” Terrifies Me

Imagine this scenario:

You enter your dentist’s office as a follow-up visit to the 6-month checkup you had last week. You’re nervous because the checkup revealed bleeding in your gums and cracks in your fillings, all things that require your dentist’s repair on this occasion.

So, you’re there nervously fidgeting in the lobby waiting for your name to be called, envisioning all sorts of dentistry implements of torture that will soon be…

So which is better for portfolio optimization, a NISQ Quantum Computer, or Fujitsu's "quantum inspired digital annealer"?

Quantum computers come in 2 varieties, quantum annealers and quantum gate models. So far, DWave is the only company selling quantum annealers.

A third type of device is now available from Fujitsu. Fujitsu calls its device a "quantum inspired digital annealer". The Fujitsu device does not have any quantum correlation (quantum entanglement)…

Business Intelligence vs Business Analytics

Business Intelligence (BI) and Business Analytics (BA) are both used to interpret business information and create data-based action plans. The two terms are frequently used interchangeably, and many people consider one to be a subset of the other (there's some disagreement about whether BI is a subset of BA, or BA is a subset of BI). However,  it might be more accurate to describe them as two arms of successful business planning: BI tells you the…

Data Science insights after a rookie year in the industry

Countless hours of online courses haven’t prepared me for challenges in my first full-time position as a data scientist. Yes, I learned Python well enough to land the job, but the reality of developing a data science project went beyond my anticipations. Now it’s time for me to pinpoint several misconceptions and matters that are not voiced enough.

Do not take data for granted…

Data Science Job Titles to Look Out for in 2020

Data scientists are disappearing. No, not in the physical sense (no rapture here), but in the job market. The term “data science” has been a catch-all term for years, but as companies better learn what goes into hiring data science teams, the generic “data science” job titles might go the way of the dodo.

Not that we’re sad about it. Confusing job postings and a misunderstanding of the fundamentals of working in data science has led to disillusionment on both sides.…

Naive Bayes Classifier using Kernel Density Estimation (with example)

Bayesian inference is the re-allocation of credibilities over possibilities [Krutschke 2015]. This means that a bayesian statistician has an “a priori” opinion regarding the probabilities of an event:

p(d)   (1)

By observing new data x, the statistician will adjust his opinions to get the "a posteriori" probabilities.

p(d|x)   (2)

The conditional probability of an event d given x is the share of  the joint…

Schmarzo’s Favorite 10 Infographic Blogs for 2019

2019 was a year full of outstanding customer engagements and provocative teaching experiences across numerous universities.  My eyes were opened to many new opportunities to integrate economics, design thinking, big data and data science (AI / ML / DL) to further my case for a Nobel Prize in Economics (which I’d prefer not to be awarded posthumously).  That includes helping organizations:

  • Monetize a digital asset (data) that never wears out, never…
