Is it time to consider data in motion in your big data projects?

As data scientists plan and evolve their big data programs, it is time to evaluate the value of adding data in motion to the data lake. What’s the difference between data in motion and data at rest? We are all familiar with data at rest. This is the data we are most accustomed to working with. Data at rest is persistent data that is stored for some period of time on either disk or in memory like sales transaction records or account information. Data in motion, on the other hand, is…

Has Deep Learning Made Traditional Machine Learning Irrelevant?

Summary:  The data science press is so dominated by articles on AI and Deep Learning that it has led some folks to wonder whether Deep Learning has made traditional machine learning irrelevant.  Here we explore both sides of that argument.

 

On Quora the other day I saw a question from an aspiring data scientist that asked – since all the…

Correlation does not imply causation

A popular phrase tossed around when we talk about statistical data is “there is correlation between variables”. However, many people wrongly consider this to be the equivalent of “there is causation between variables”. It’s important to explain the distinction: Correlation means that once we know how one variable changes we can make reasonable deductions about how other variables change There are several variants of correlation:

1. Positive…

Why Data Decays so Fast?

People change jobs, get promoted and move home. Companies go out of business, expand and relocate.  Every one of these changes contributes to data decay. It’s been said that business databases degrade by around 30% per year, but why?

A report by IDG states that companies with effective data grow 35% faster year-on-year. However, for this to…

Objectification of Incidents

Probably like most people, I tend to recognize data as a stream of values. Notice that I use the term values rather than numbers although in practice I guess that values are usually numerical. A data-logger gathering one type of data would result in data all of a particular type. Perhaps the concept of “big data” surrounds this preconception of data of type except that there are much larger amounts. Consider an element of value in symbolic terms, which I present below: there is an index such…
