According to Wikipedia, MongoDB is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB avoids the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.

Here I discuss my prediction about the worst 15-year long (yet unabated) real estate bubble: this is an example where visualizations, when not carefully selected and put into context, can be seriously misleading, even for top experts. Here I also provide some hints to help you avoid these visualization traps. This article shows how data scientists should think, when confronted to charts such as the one below.…Continue

In recent blogs, I wrote about using codified narrative as a form of data. I also discussed using attribution models to systematically evaluate codified narrative for ontological constructs: e.g. "child abuse" "physical confinement" "cannibalism." I provide a brief overview of these topics a bit later in the blog. The third important piece to make use of narrative data involves "attribution profiling" in a process that I call "catching scent." Following the odour of data involves…Continue

What does big data know about you?
Quite a lot.
Every time we use a computer, access our phones, or open an app on a tablet, we’re leaving a digital trail. Most people are vaguely aware that Google knows what they’ve searched for, or that Facebook knows who their friends are, but it goes much, much deeper than that.…Continue

NEHI puts a price on patients not adhering to treatment. It’s $290 Billion worth of a new problem for the pharmaceuticals industry – getting beyond the pill to influence the behaviours or patients and thereby influence the outcomes on which their reimbursements, and ultimately profitability, depends. Investment in patient access and adherence technology and programs is set to increase exponentially over the next five years, but if this investment is going to pay off, the data strategy to…Continue

If we tackle a supervised learning problem, my advice is to start with the simplest hypothesis space first. I.e., try a linear model such as logistic regression. If this doesn't work "well" (i.e., it doesn't meet…Continue
