Highlights from the Deep Learning Summit: Neural Networks Demystified and Domain Adaptation
I recently had the pleasure of attending REWORK’s Deep Learning Summit in Boston. Two topics stood out to me as eminently huge forces in deep learning: a powerful way to understand neural networks (and its practical benefits), and domain adaptation. These are both topics the community should be aware of, so let’s discuss them. 1….
Teaching Machines: What is Machine Learning?
Data Science and machine learning have generated a lot of discussion surrounding them in the past few years.

Self-Service or IT Managed BI Tools – What You Need to Know
My non-techie spouse just built his own small business website for a fledgling custom guitar-making business. All by himself. It did not take him long – some dragging and dropping, a little typing and a picture upload later – and it looks good. Ten years ago he would not have even attempted it and instead…
Enabling Hadoop in the Amazon Cloud
At Excella, we wanted a Big Data sandbox area for our research and prototyping efforts. We frequently work in the Amazon Cloud and chose Amazon’s Elastic Compute Cloud (EC2) – a “use what you need when you need it” virtual computing environment that allows subscribers to launch computing instances with different configurations. Here are five…
Agile Data Conversion: 5 Keys to Success
Imagine that you are a Product Owner on the replacement of a legacy operations system using an Agile approach.

In contrast, I see a plethora of roles from finance, marketing, sales…
