As a data scientist who has been munging data and building machine learning models in tools like R, Python and other software(s) (open source and proprietary), I had always longed for a world without technical limitations. A world which would allow me to create data structures (data scientists usually call them vectors, matrices or dataframes) of virtually any…Continue

In this post, I'll explore the new AWS Machine Learning services.
The problem we are trying to solve is to classify auto accident severity given a set of features. I'll not go into further details of the data set and what classification algorithms,etc. here since the goal of this blog is to explore the new AWS Machine Learning service step by step.
In the next blog post, I'll explore another service: Microsoft Azure Machine…

When I talk about "the institutional response," I am referring to an increasingly common occurrence: a standardized or large-scale approach is supported, promoted, and applied by a particular institution - sometimes governmental in nature - premised on its apparent suitability or superiority to achieve desirable outcomes. I suspect that in recent years, there has been a push to get citizens to file their income tax returns electronically. I know that in Canada, it has become difficult…

In my experience at startups and large companies, good analytics often boils down to the availability of organized data to answer business questions. This is especially important for digital marketers, with the audience data from many channels pouring in and the need to stay on top of key metrics.
Seemingly simple questions can spin up the entire MarTech engineering team!

Over the past 6 months I have seen the number of big data projects go up significantly and most of the companies I work with are planning to increase their Big Data activities even further over the next 12 months. Many of these initiatives come with high expectations but big data projects are far from fool-proof. In fact, I predict that half of all big data projects will fail to deliver against their expectations.
Failure can happen for many reasons, however there are a few…Continue
