Machine Learning – Can We Please Just Agree What This Means

Summary:  As a profession we do a pretty poor job of agreeing on good naming conventions for really important parts of our professional lives.  “Machine Learning” is just the most recent case in point.  It’s had a perfectly good definition for a very long time, but now the deep learning folks are trying to hijack the term.  Come on folks.  Let’s make up our minds.

Using Convolutional Neural Networks to detect features in sattelite images

In a previous blog post we have seen how to build Convolutional Neural Networks (CNN) in Tensorflow, by building various CNN architectures (like LeNet5, AlexNet, VGGNet-16) from scratch and training them on the MNIST, CIFAR-10 and Oxflower17 datasets.

It starts to get interesting when you start thinking about the practical applications of CNN and other Deep Learning methods.  If you have been following the latest technical developments you probably know that CNN’s are…

Trump Solves Famous Mathematical Conjecture

In an email sent to Putin and intercepted by hackers, Donald Trump mentions the result below. However, Trump wrote that he did not have enough space in his message to add the proof, a bit like Fermat when he wrote about his big theorem proved 300 years later. A teacher in New Hope Middle School (Pennsylvania) asked her students to verify if the statement was correct, and found it to be true. In his email, Trump wrote that he planned to leverage this result to find new prime numbers. It was…

The New Face of Credit Card Fraud

You would think that I am going to talk about new levels of sophistication achieved by cybercriminals. No, here I discuss a different trend: Outright credit card fraud committed by big  businesses, in this case Amazon. 

While this is about my experience, and involves more than $1,000 in fraudulent transactions over the course of two weeks, I have no reason to believe that I was specifically targeted. Maybe a million customers have faced the same issue. The fraud was reported to the…

Free eBook: Applied Data Science (Columbia University)

Published in 2013, but still very interesting, and different from most data science books. Authors: Ian Langmore and Daniel Krasner.. This book focuses more on the statistics end of things, while also getting readers going on (basic) programming & command line skills. It doesn't, however, really go into much of the stuff you would expect to see from the machine learning end of things. …

Anatomy of Chatbots

Introduction

Natural language conversation is one of the most challenging artificial intelligence problems, which involves language understanding, reasoning, and the utilization of common sense knowledge. Previous works in this direction mainly focus on either rule-based or learning-based methods. These types of methods often rely on manual effort in designing rules or automatic training of model with a particular learning algorithm and a small amount of data, which…
