Applying Bayes Theorem to a Big Data World

Bayes Theorem One of the challenges in analyzing Big Data is of course its volume - there is just so much of it. Then mix in high velocity, or Fast Data and standard analytical methodologies to make sense of it breakdown, and become cumbersome and ineffective. Machine learning techniques that self-adjust and improve over time [...]

Machine Learning: Understanding Feature Selection

Feature selection is a part of Machine Learning that can be very difficult to grasp for someone not intimately familiar with statistics. It is the intent of this blog to demystify what feature selection is and the techniques that can be used to accomplish it. What is Feature Selection? Making Predictions and Cluster Analysis are [...]

Cluster Analysis and Big Data

My last blog on machine learning discussed different types of artificial intelligence that can be applied to Big Data. This article will discuss cluster analysis, a form of Unsupervised Pattern Recognition. Let’s start with a basic definition. Pattern recognition algorithms are used to detect regularities in data, and they come in two basic flavors: supervised [...]

Artificial Intelligence and Big Data

Artificial Intelligence Artificial Intelligence (AI) has been around for decades. However, recently with the advent of “Big Data”, it’s been getting more attention. Wikipedia says this about Artificial Intelligence: “In computer science, the field of AI research defines itself as the study of ‘intelligent agents’: any device that perceives its environment and takes actions that [...]

Curious about JavaScript performance, but don’t want to work hard?

There’s an easy way to determine if your JavaScript is inefficiently written. There’s no need to instrument every JavaScript function with code that logs timings and then analyze log files. With the use of W3C User Timing API’s use of “marks” as well as some creative JavaScript -ing, this can be done with minimal code. [...]
