It has become clear over the last few months that mainstream media on both sides are stretching the truth, if not reporting fake stories first published in outlets such as The Onion. The famous picture below (about the number of people attending Trump's inauguration versus Obama 8 years ago) raises interesting questions.

How Big Data Is Boosting Emergency Preparedness

We never feel prepared when disaster strikes – from the devastation of Hurricanes Katrina and Sandy to the Pacific earthquake that moved the main island of Japan and caused several meltdowns at a nuclear power plant in 2011, the destruction of both natural and manmade disasters can seem both immeasurable and unpredictable.

Data Science Using Docker Containers

It's been few months since I started using docker containers for my data science experiments. Docker Containers are becoming very popular these days for reproducible experiments.

Statistics Means Never Having to Say You Are Certain!

When I was a kid there was a popular movie quote going around, "Love means never having to say you're sorry" which was the basis behind this T-shirt my wonderful mother got me.  It means very different things to different people, "Statistics means never having to say you’re certain”.  I like the shirt, but these differences are very…

Adapting an Algorithm to Real-time Applications

Below are some images generated by an algorithm that I originally created to study stocks. The stock in this case is Yahoo! in the early 2000s. I realize that none of these images resemble conventional stock market patterns. Keep in mind that algorithms by nature interact with the data. They don't simply restate the numbers in graphical form. An algorithm designed to deal with historical stock trading data can be modified to deal with the data in real-time. However, there is no inherent…

Can computers think? An epistemology for Artificial Intelligence

As AI enters our homes through smart home devices or tries to conquer our streets through self-driving cars, one need not be a Luddite to contemplate the potentially heavy implications of AI upon our daily lives and livelihood. The key to answering the question and indeed to understand the ultimate limits of AI is to ask if machines can really think.
