Got your attention, right? Statistics are being used more strategically these days to convince readers to act or believe in certain ideas because they drive decisions in our personal and business lives. This strategy thrives in today’s headline-driven world as readers are drawn to eye-popping statistics and form their opinions accordingly.

This article contains in-depth algorithm overviews of the K-Nearest Neighbors algorithm (Classification and Regression) as well as the following Model Validation techniques: Traditional Train/Test Split and Repeated K-Fold Cross Validation. The algorithm overviews include detailed descriptions of the methodologies and mathematics that occur internally with accompanying concrete examples. Also included are custom, fully functional/flexible frameworks of the above algorithms built from scratch using primarily NumPy. …


As the world continues to fight to contain the spread of COVID-19, our team at the Boulevard Consulting Group has, like millions of others, been working remotely since mid-March and staying at home in an effort to practice social distancing. As might have been the case for you, more time at home has meant plenty of time to binge-watch.

Arlington, VA — February 14, 2020 — Today, roughly 20 percent of all relationships and 17 percent of all marriages begin online.[1] With about 2,000 dating apps operating in the US and almost 8,000 total operating worldwide, online dating has quickly become a multi-billion-dollar industry with most projections predicting at least $3 billion in revenue in the US alone for 2020.[2][3] Over the years, companies within the digital space have sought to remain relevant by integrating new technology to push the boundaries on efficiency — the online dating industry is no different. One subset of technologies that has proven indispensable for these issues is Artificial Intelligence (AI) and Machine Learning (ML). Both have quickly become no stranger to dating apps around the world. Nowadays, apps like Badoo, Betterhalf, eHarmony, OkCupid, Hinge, Tinder, and Match.com …
