Data Engineer and Business Analyst Might be the Best Data Science Opportunities

Summary: Not everyone wants to invest the time and money to become a data scientist, and if you’re mid-career the barriers are even higher.  If you still want to be deeply involved in the new data-driven economy and well paid, the growth rate and opportunities as a data engineer or business analyst need to be on your radar screen.

How Data Scientists Spend their Time - Nice Cartoon

Data scientists spend 80% of their time preparing and cleaning their data. They spend the other 20% of their time complaining about preparing and cleaning their data.

This was posted by Kirk Borne on his Twitter account. Not sure who created the cartoon. Do we all spend 80% on our time on something, and the remaining 20% on something else? In my case, I spend 20% of my time writing articles (usually research articles that the layman can understand, and sometimes articles like…

Two Questions to Ask to a PhD Candidate for a Leadership Role

These are not business questions, but soft questions that should make any PhD candidate relaxed, even intrigued, and open to talk freely. There is no wrong answer, these are open questions, but some answers could hint that the candidate is still in his/her PhD bubble, feeling superior, not flexible, and unable to see the big picture behind the apparently innocent question. These questions were asked discretely, none of the responders knew about my PhD mathematical background. …

Fractional Exponentials - Dataset to Benchmark Statistical Tests

I described here a strange type of function, that is nowhere continuous but relatively easy to integrate using probabilistic arguments. I call it the fractional part of parameter p of a function g(x), and it is denoted as g(x, p). We focus here on g(x) = exp(x). It is obtained by removing a number of terms (usually infinitely many) in the Taylor series of g(x). For instance, by removing all…

Humans-in-the-Loop? Which Humans? Which Loop?

Background

For people working in Artificial Intelligence, the term “Human-in-the-Loop” is familiar i.e. a human in the process to validate and improve the AI. There are many situations where it applies, as many as there are AI applications. However. there are still some distinct different ways it can be deployed even within the same application.

Contact Center Example

Let’s take for example the automation of a contact center. A…

The importance of Big Data in AI technologies

To say that AI is big data is to overstate things a bit. And yet, without big data, AI wouldn’t be where it is today. In the last few decades, the two technologies have advanced in lock-step. Largely because without big data, however clever the AI programmers were, they couldn’t get past the theoretical stage.

Mainly, this is down to what big data is used for. Through data, it is possible to train AI and thereby give them the opportunity to learn things. The more data is available,…

Deciphering information and misinformation: Inspired by the book "A Field Guide to Lies and Statistics"

They are in combat side-by-side, staring back at you like identical twins, one of them will help you and the other one will hurt you, who are they?

They are information and misinformation, writes neuroscientist Daniel Levitin in his book “A field guide to lies and statistics”.

But are these two really fighting on a level playing field? New research findings published in Science magazine show that things are much more serious than we might have thought.…

Behind Social Media

As a provider of social networking services (social media) should filter out what data can be accessed by third parties. A sign "Like" for some people may not be so important, but do you know that based on that sign I can know who can be said to be influential (central person). It…

Transfer Learning –Deep Learning for Everyone

Summary: Deep Learning, based on deep neural nets is launching a thousand ventures but leaving tens of thousands behind.  Transfer Learning (TL), a method of reusing previously trained deep neural nets promises to make these applications available to everyone, even those with very little labeled data.

Technical Boundary Analysis

About a month ago, I posted a blog on “Technical Deconstruction.” I described this as a technique to break down aggregate data to distinguish between its contributing parts: these parts might contain unique characteristics compared to the aggregate.  For instance, I suggested that it can be helpful to break down data by workday - that is to say, maintaining separate data for each day of the week.  I said that the data could be further deconstructed perhaps by time period and employee: the…
