Elastic Is a Great Paradigm When “All You Can Eat Data Consumption” Is the Goal

Guest blog post.

Today, people are no longer looking to reduce their data consumption. In fact, if anything, they want more data originating from more sources and with more diversity than anyone could have ever imagined. As we pioneer a world where data can be digested easily, software solutions need to be engineered so they can expand to meet the customers demand. Increasingly, and because of this trend, more and more software…

Data Structure Graph - The application of Graph theory to Architecture

How does centrality affect your Architecture?

Some time ago, I was responsible for a data architecture I had mostly inherited. There were a number of tweaks I worked to on to refine the monolithic nature of the main database. It was a time of upheaval in this organization. They had outgrown their legacy Computer Telephony Interface application. It was time to create something new. 
A large new application development team was brought in to develop some new…

Feature Scaling and Normalization

Very long article posted by Sebastian Raschka in 2014. Here we only provide the table of content, and a chart showing the results of PCA applied to a wine dataset. A link to the full version is provided below. The article is rather technical and uses Python, including the scikit-learn, numpy. pandas and matplotlib libraries. Interesting for anyone working with scores and looking for normalization, though personally, I don't like PCA (produces meaningless reduced variables and sensitive…

The Quantified Workplace: Big Data or Big Brother?

Companies have more data on staff than ever before in history and big data analytics is making its way into HR practices fast. Analyzing staff performance is nothing new, but the extent to which we can now collect and analyze such data is going beyond all norms.

Sociometric Solutions puts sensors into employee name badges that can detect social dynamics in the workplace. The sensors report on how employees move around the workplace, with whom they speak, and even the tone of voice…

Big Data In The Amazing World of Gaming

Big Data is big in gaming. Take Zynga, the company behind Farmville, Words with friends, and Zynga Poker. Zynga positions itself as a maker of “social” games, which are generally played on social media platforms (rather than game consoles like Nintendo, Xbox or PlayStation) and take advantage of the connectivity with other users that those platforms offer.…

Tools to automate... more time to innovate

I absolute loved the point made by Matthew Napleton - we must make tools easier to use!

That doesn't mean we eliminate the need for human interaction. As long as a decision has to be made, a machine can get you further, faster but the magic still happens when a person applies their intellect to the process.

Before leaping to the notion that automation is going…

7 Amazing Big Data Myths

Here is my top 7 list of daft things that some people say about Big Data.

I think that Big Data does play a role in some businesses. I also think that some of the basic distributed file store and text search technologies can be usefully employed, in non-traditional indexing, counting and correlation. However, there is an awful lot of nonsense said about Big…

Data is Immortal, but Not Immune to Decay

Data exists in a dangerous state of near-non existence. Few businesses would risk not having backups in place. With cloud computing becoming commonplace in enterprise, we’ve come to accept that our data will be replicated and stored in duplicate.

Even data that is intentionally deleted can often be recovered. When Yahoo! purchased Geocities,…

Your Math Is All Wrong: Flipping The 80/20 Rule For Analytics

I was deep into a presentation at a major retailer. In the darkened room, a lone hand shot up. “John, we spend 80% of our time on data load and prep. Only 20% is used to produce analytics. We don’t like that ratio.”

The speaker was right. About 80% of the analytics process is spent on data preparation and loading. Numerous examples come to mind. I remember a project for an auto insurance company using telematics and driver behavior. The one-off code to prepare the data took three days…
