Feed: Featured Blog Posts - Data Science Central. Author: William Vorhies. Summary:  A little history lesson about all the different names by which the field of data science has been called, and why, whatever you call it, it’s all the same thing. A little reminiscence, or for those of you who are only recently data scientists, a little history lesson.  Our profession of finding the signal in the data, be that supervised or unsupervised got underway in the 90s.  In the last 20+ years we’ve been called by a variety of names.  It’s not at all clear that as those ...

Multiple venues Since next year’s tournament is an anniversary edition, it will be played in venues all across Europe. This is very different from previous events, which have generally taken place in a single host country.  ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Bill Schmarzo. Sustaining industry averages and benchmarks are the antithesis of innovation and a great way to ensure average performance. Doing whatever everyone else is doing is a “paving the cow path” management mentality, lacking aspirational goals which are critical for organizations to fuel innovation and create customer and market differentiation. Which brings me to why I teach. As my students and I work through their “Thinking Like a Data Scientist” exercises together, I always learn something new from them. And not one of these students – tomorrow’s business and society ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: Stephanie Glen. At the time of writing, I'm a 52 year-old working in the fields of mathematics and data science. In mathematics, that makes me well-seasoned (and probably well-tenured, if I had chosen to continue in academia). In data science, some would consider me a dinosaur. In fact, many older people considering a career in data science might be put off by the thought that data science is tough to break into at a later age. But is that statement true? Should the over 50 crowd put down their textbooks and ... Read More

Feed: Featured Blog Posts - Data Science Central. Author: David Harris. In my prior blog post, I wrote of a clever elf that could predict the outcome of a mathematically fair process roughly ninety percent of the time.  Actually, it is ninety-three percent of the time and why it is ninety-three percent instead of ninety percent is also important. The purpose of the prior blog post was to illustrate the weakness of using the minimum variance unbiased estimator (MVUE) in applied finance.  Nonetheless, that begs a more general question of when and why it should be used, or a Bayesian ...

Feed: Featured Blog Posts - Data Science Central. Author: Lucas Finco. (I will give you a hint. It’s in the name.) Scientists! This post is intended as a response to an interesting discussion on LinkedIn started by analytics manager at Ford, Michael Cavaretta.  https://www.linkedin.com/posts/michael-cavaretta-ph-d-795a965_indus....  He asked what hires make the best data scientists. In my real-world experience in the data science field, I find that physicists make the best data scientists.  Why?  Because physicists work at the intersection of math and reality.  They have been trained to hypothesize ideas about how things work, and then to design experiments to test ...

Currently, Microsoft is making the new Excel core-features available to every user, regardless of your Office 365 license. Thanks to the Microsoft naming conventions, it is easy to confuse the new features with existing ones. That being said, Power Query and Power Pivot are not the same things as Pivot Tables, which you have likely been using for years. Power Query (M-Language)Data preparation is very time-consuming. Power Query allows you to cleanse large amounts of data ... Read More
