Logistic Regression in One Picture

Logistic regression is regressing data to a line (i.e. finding an average of sorts) so you can fit data to a particular equation and make predictions for your data. This type of regression is a good choice when modeling binary variables, which happen frequently in real life (e.g. work or don't work, marry or don't marry, buy a house or rent...).

This growing hobby has attracted participants from all walks of life. Though computer games have been around for years, MMORPGs are different in numerous facets. While a healthy form of entertainment for some men, women, and children, others develop something more akin to addiction. Are these increasingly…

D3 for Data Scientists, Part I: A re-usable template for combining R and D3 to build interactive visualizations

By Peter Cooman

The path to D3 mastery is dark and full of terrors. D3 itself is a JavaScript (JS) library and on top of that, you’ll need a basic understanding of HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) to get the most out of it. If you’re a data scientist, chances are JavaScript, at best, ranks as your fourth language, after R, Python,…

Bias Variance Trade Off

Deep Learning is a highly empirical domain which majorly focusses on fine-tuning the various parameters. The choice of these parameters defines the accuracy of the model. So, it becomes important to choose such parameters wisely. Choosing the parameters based on intuition might not work every time which can degrade the performance of the model drastically. Also, a considerable amount of time and effort will go in vain while selecting the values of parameters based…

Using Data Science and Google Cloud to Win March Madness…Well, Not Really

I suck at the NCAA March Madness® bracket selection process.  I let my personal biases get in the way of making decisions based upon the numbers.  I over-rate the well-known Big Ten conference and under-rate the lesser-known Mid Majors and fall in love with the most recent team I saw on TV win their conference tournament.  You see, I fall prey to all the common decision-making traps – recency bias, over-confidence, anchoring, risk aversion, framing…

K-nn Clustering Explained in One Picture

This is a simple overview of the k-NN process. Perhaps the most challenging step is finding a k that's "just right". The square root of n can put you in the ballpark, but ideally you should use a training set (i.e. a nicely categorized set) to find a "k" that works for your data. Remove a few categorized data points and make them "unknowns", testing a few values for k to see what works.…

Is Robotic Process Automation (RPA) Really AI?

Summary:  Based on a McKinsey study we reported that 47% of companies had at least one AI/ML implementation in place.  Looking back at the data and the dominance of RPA as the most widely reported instance makes us think that the number is probably significantly lower.

Training for Context: The Importance of Word2Vec

We’ve all experienced the great data rush as companies push to use analytics to drive business decisions. After all, the proliferation of data and its intelligent analysis can change entire company trajectories.
