What Exactly is Artificial Intelligence and Why is it Driving me Crazy

Summary:  Advanced analytic platform developers, cloud providers, and the popular press are promoting the idea that everything we do in data science is AI.  That may be good for messaging but it’s misleading to the folks who are asking us for AI solutions and makes our life all the more difficult.

 

Arrgh!  Houston we have…

Are we comparing the countries correctly ?

How many times you have compared your homeland to another country when you have watched a foreign language movie/show or when you have traveled to a different country for a business or leisure trip ? I have found myself doing so many times and also had conversations and debates with friends.What I have observed in my discussion is that our brain very quickly comes to a decision on the basis of what it sees at the first glance, very few people control their mind and think about various…

What Happens when our Computers get Smarter than we are?

Artificial intelligence is getting smarter by leaps and bounds -- within this century, research suggests, a computer AI could be as "smart" as a human being. And then, says Nick Bostrom, it will overtake us: "Machine intelligence is the last invention that humanity will ever need to make." A philosopher and technologist, Bostrom asks us to think hard about the world we're building right now, driven by thinking machines. Will our smart machines help to preserve humanity and our values -- or…

The Theory of Theory

Since I am sometimes asked to explain phenomena in the absence of data, it becomes necessary to determine what data is required to explain phenomena.  Some would say the best approach is to develop and test a hypothesis - to start filling a void of space with pinholes of light - until there are enough lit pinholes to provide a working theory.  This is not to say that a few additional…

Big Data Isn’t a Thing; Big Data is a State of Mind

“Big Data is dead.” “Big Data is passé.”

“We no longer need Big Data; we need Machine Learning now.”

As we end 2017 and look forward to big (data) things in 2018, the most important lessons of 2017 – in fact, maybe the most important lesson going forward – is that Big Data is NOT a thing. Big Data isn’t about the volume, variety or velocity of data any more than car…

Lessons in Becoming an Effective Data Scientist

I was recently a guest lecturer at the University of California Berkeley Extension in San Francisco. On a lovely Saturday afternoon, the classroom was crowded with students of all ages learning the tools of the modern economy. The craftspeople of the “Analytics Revolution” were busy learning new skills and tools that will prepare them for this Brave New World of analytics. I was blown away by their dedication!

As we teach the next generation, it’s important…

Supervised Learning Use Cases: Low-Hanging Fruit in Data Science for Businesses

In the past few years, machine learning (ML) has revolutionized the way we do business. A disruptive breakthrough that differentiates machine learning from other approaches to automation is a step away from the rules-based programming.  ML algorithms allowed engineers to leverage data without explicitly programming machines to follow specific paths of problem-solving. Instead, machines themselves arrive at the right answers based on the data they have. This capability made business…

Automated Text Classification Using Machine Learning

Text Classification

Digitization has changed the way we process and analyze information. There is an exponential increase in online availability of information. From web pages to emails, science journals, e-books, learning content, news and social media are all full of textual data. The idea is to create, analyze and report information fast. This is when automated text classification steps up.

Text classification is a smart…
