The rise of advanced analytics

In five short years the world of analytics has changed immeasurably. Five years ago Hadoop was reaching the peak of the hype cycle and it acted as a wake-up call to businesses that perhaps there is value in their data.

This evolved more recently into big data analytics. Although Hadoop opened a door to big data, it wasn’t actually the right tool for what most businesses needed – fast analytics, interactive experimentation with data and exploratory analysis of…

The Environmental Cost of Big Data: It’s Higher Than You Think

One of the major selling points of collocating a business’ servers in a data center is the reduced energy consumption. Small businesses have long been sold on the idea of reducing the in-house power resources necessary to operate the network, which in many cases had moved well beyond a simple server on someone’s desk to a dedicated space requiring a specialized HVAC system…

Q&A: The Transformative Power of Big Data Paired with Data Science

Data analytics is a mature discipline at this point, and even those outside the data science world generally understand what it’s all about. Modern data science, however, is still new enough to spur questions. Vincent Glanville, Executive Data Scientist at Data Science Central, spoke with Roy Wilds, Chief Data Scientist from PHEMI, a Vancouver-based big data startup, about the best way to educate people…

The Fundamental Statistics Theorem Revisited

In this article, we revisit the most fundamental statistics theorem, talking in layman terms. We investigate a special but interesting and useful case, which is not discussed in textbooks, data camps, or data science classes. This article is part of a series about off-the-beaten-path data science and mathematics, offering a fresh, original and simple perspective on a number of topics. Previous articles in this series can be found…

Warning! Get Ready for Regulations that Restrict Your Analytics

Summary:  AI and predictive analytics are now so prevalent in our day-to-day lives that it has raised the attention of the government, particularly about how certain groups might be adversely impacted.  As data scientists we naturally want to have free reign to let the data speak as best it can, but as this report from the White House shows, we need to be prepared for some push back.

 

The last 10 years have been glorious days for data science and…

Massive Internet Attack Floods the World with Fake Data

Reddit is now at the center of this attack that impacts millions of top domains (most of the Internet) since November 30. While Reddit appears at first glance as the perpetrator, it is actually the victim. This "behind the scene" scheme run from Russia generates huge amounts of fake traffic - as much as 10% of the entire Internet traffic.

It is not caught by Google Analytics, and thus it results in phony web traffic statistic and flawed reports, which is the main issue people are…
