Difference of Data Science, Machine Learning and Data Mining. Data is almost everywhere.
The amount of digital data that currently exists is now growing at a rapid pace. The number is doubling every two years and it is completely transforming our basic mode of existence. According to a paper from IBM, about 2.5 billion gigabytes of data had been generated on a daily basis in the year 2012. Another article from Forbes informs us that data is growing at a pace which is faster than ever. The same article suggests that by the year 2020, about 1.7 billion of new information will be developed per second for all the human inhabitants on this planet. The Data within Big Data and the myth around Unstructured Data - Cognitive Today :The New World of Cognition and Advanced Analytics. What Led to the Recent Huge Buzz Around Analytics? Price discrimination and downward demand spiral are widely used analytical concepts and practices in the Airlines and Hospitality industries respectively, long before the term Big Data Analytics was even coined.
Incidentally, these concepts have been taught in global elite b-schools for decades. So why are analytics, which has been there in practice for decades, experiencing a meteoric rise suddenly? To answer this question, we need to get the Big Picture. Below are key factors that led to the huge buzz around analytics today. Machine Learning Explained: Algorithms Are Your Friend. We hear the term “machine learning” a lot these days, usually in the context of predictive analysis and artificial intelligence.
Machine learning is, more or less, a way for computers to learn things without being specifically programmed. But how does that actually happen? The answer is, in one word, algorithms. Algorithms are sets of rules that a computer is able to follow. Big Data Analytics: 11 Case Histories and Success Stories. Welcome. The What and Where of Big Data: A Data Definition Framework. Figuring Out How IT, Analytics, and Operations Should Work Together. A new set of relationships is being formed within companies around how people working in data, analytics, IT, and operations teams work together.
Is there a “right” way to structure these relationships? Data and analytics represent a blurring of the traditional lines of demarcation between the scope of IT and the responsibilities of operating divisions. Consider the core mission of the modern IT department: Taking in all the technology “mess” (often from several different divisions), developing the necessary competencies, and delivering savings and efficiency to the company.
Many IT organizations, having achieved this original mission, now are turning to the next thing, which is innovation. Enter data and analytics, which provide an opportunity for such innovation. Let’s look at four examples of how different corporations responded when faced with this question. Analytics: Turning a Flood of Data into Valuable Information. The benefits that come from data analytics are many — it's helped reduce inmate populations, improve reliability of emergency medical services and reduce traffic fatalities, to name just a few.
Though some government agencies are slow to embrace it due to limited capital or sheer intimidation in the face of disparate systems and fragmented technologies, others have taken hold of the proverbial horns and started the process of improving their daily operations by way of the data. And during the California Technology Forum held Aug. 11 in Sacramento, state and local officials delved into the insights gained from the exponential increase of data — and where teams need to focus their energy to turn this flood of data into valuable information. “From that, I understood that big data wasn’t just the amount of data we were talking about," he said. "There are many other things we need to consider.” Graham called the process employed in Los Angeles the collaborative leadership model.

Data Visualisation: What's the big deal? The concept of using pictures to understand complex information — especially data — has been around for a very long time, centuries in fact.
One of the most cited examples of statistical graphics is Napoleon’s invasion of Russia mapped by Charles Minard. The maps showed the size of the army and the path of Napoleon’s retreat from Moscow. It also included detailed information like temperature and time scales, providing the audience with an in-depth understanding of the event. However, as with most things, it’s technology that has truly allowed data visualisation to take the stage and get noticed. IT Operations Analytics. In the fields of information technology and systems management, IT Operations Analytics (ITOA) is an approach or method applied to application software designed to retrieve, analyze and report data for IT operations.
ITOA has been described as applying big data analytics to large datasets where IT operations can extract unique business insights. In its Hype Cycle Report, Gartner rated the business impact of ITOA as being ‘high’, meaning that its use will see businesses enjoy significantly increased revenue or cost saving opportunities. By 2017, Gartner predicts that 15% of enterprises will use IT operations analytics technologies to deliver intelligence for both business execution and IT operations. Definition History

Big Data A to ZZ – A Glossary of my Favorite Data Science Things. What Really Is Big Data? Big Data is THE biggest buzzwords around at the moment and I believe big data will change the world. Some say it will be even bigger than the Internet. What's certain, big data will impact everyone's life. Having said that, I also think that the term 'big data' is not very well defined and is, in fact, not well chosen. How is Big Data Used in Practice? 10 Use Cases Everyone Must Read.

Or perhaps you think of receiving some kind of personalized advertisement from a retailer. Getting big impact from big data. What’s the Big Data? 12 Definitions. Last week I got an email from UC Berkeley’s Master of Information and Data Science program, asking me to respond to a survey of data science thought leaders, asking the question “What is big data”?
I was especially delighted to be regarded as a “thought leader” by Berkeley’s School of Information, whose previous dean, Hal Varian (now chief economist at Google, answered my challenge fourteen years ago and produced the first study to estimate the amount of new information created in the world annually, a study I consider to be a major milestone in the evolution of our understanding of big data. The Berkeley researchers estimated that the world had produced about 1.5 billion gigabytes of information in 1999 and in a 2003 replication of the study found out that amount to have doubled in 3 years. The traditional database of authoritative definitions is, of course, the Oxford English Dictionary (OED). But this is 2014 and maybe the first place to look for definitions should be Wikipedia.

There is no greater impediment to the advancement of knowledge than the ambiguity of words, Thomas Ried once said. That rings very true when it comes to the way companies today are throwing around buzzwords like “big data” or “easy to use BI,” and only loosely defining the words, if at all, leaving everyone unsure of their meaning. Researching and choosing the best business intelligence solution for your company is challenging enough, so here are some definitions to help you sort through the marketing hype over buzzwords and really define the technical terms, their nuances, and what to look for in a BI tool.

Put simply, Hadoop can be thought of as a set of open source programs and procedures (meaning essentially they are free for anyone to use or modify, with a few exceptions) which anyone can use as the “backbone” of their big data operations. I’ll try to keep things simple as I know a lot of people reading this aren’t software engineers, so I hope I don’t over-simplify anything – think of this as a brief guide for someone who wants to know a bit more about the nuts and bolts that make big data analysis possible.
