Why Zipf's law explains so many big data and physics phenomenons

The Zipf's law states that in many settings (that we are going to explore), the volume or size of entities is inversely proportional to a power s (s > 0) of their ranking. This has important implications in predictive modeling, discussed below. The processes that create this type of dynamic are not well understood. It is the purpose of this article to explain the underlying mechanics. The traditional example for the Zipf distribution is the distribution of Internet…

16 analytic disciplines compared to data science

What are the differences between data science, data mining, machine learning, statistics, operations research, and so on?

Here I compare several analytic disciplines that overlap, to explain the differences and common denominators. Sometimes differences exist for nothing else other than historical reasons. Sometimes the differences are real and subtle. I also provide typical job titles, types of analyses, and industries traditionally attached to each discipline. Underlined domains are…

Data Analysis To Data Science

(This is a paper presented in a local meet of statisticians; a summary of various discussions)

​Data analysis, one of the main requirements for Research has transformed into ‘Data Science’ which is considered as one of the most important concepts in the current internet enabled scenario. May be it is for a different purpose, where the requirement of manpower in data analysis related issues is huge. Business decisions started moving towards data aided decisions and the availability of data… Continue

Tutorial: How to detect spurious correlations, and how to find the real ones

Specifically designed in the context of big data in our research lab, the new and simple strong correlation synthetic metric proposed in this article should be used, whenever you want to check if there is a real association between two variables, especially in large-scale automated data science or machine learning projects. Use this new metric now, to avoid being accused of reckless…

How to identify the right data scientist for your company

Should you hire someone who knows all the most recent flavors of logistic regression? Or an Hadoop developer?

In my opinion, this is the wrong strategy. These employees are very expensive (at least $120k per year), and they might not bring the ROI that you expect. At least, if going in that direction, hire someone favoring simple, scalable, robust, automated solutions over anything else. To automate, you need someone great at developing…

Six categories of Data Scientists

We are now at 9 categories after a few updates. Just like there are a few categories of statisticians (biostatisticians, statisticians, econometricians, operations research specialists, actuaries) or business analysts (marketing-oriented, product-oriented, finance-oriented, etc.) we have different categories of data scientists. First, many data scientists have a job title different from data scientist, mine…

Zipfian Academy versus Data Science Apprenticeship

Both programs are alternatives to university curricula and traditional education. Both are run by leading industry professionals rather than academic leaders. Zipfian offers a 12-week program, the Data Science Apprenticeship (DSA, organized by us at DSC - Data Science Central) is a 6-month program.…
