Artificial Intelligence as a Service - AIaaS

Suddenly, artificial intelligence is everywhere. Are you AI ready if not then be ready to be read in history books. Are we not missing the fact that artificial intelligence is about the people, not the machines. Technology and non technology companies are now investing and brining out the real and materialistic values of Artificial Intelligence to the real world. Its almost…

Have You Heard About Unsupervised Decision Trees

Summary: Unless you’re involved in anomaly detection you may never have heard of Unsupervised Decision Trees.  It’s a very interesting approach to decision trees that on the surface doesn’t sound possible but in practice is the backbone of modern intrusion detection.


I was at a presentation recently that focused on stream processing but the use case presented was about anomaly detection.  When they started talking about unsupervised decision trees my…

How Mathematical Discoveries are Made

In one of my previous articles, you can learn the process about how discoveries are made by research scientists, from stating the problem, exploratory analysis, testing, simulations, data science guesswork, all the way to the discovery of a new theory and state-of-the-art statistical modeling,including new, fundamental mathematical/statistical equations.

This is a unique occasion to discover the creative path followed by inventors. Traditional research papers do not explain how a new…

Stored Procedures: A Seemingly Nice Tool with Hidden Problems

The stored procedure is as widely used in database computing as the controversy around the technique is long-standing. By analyzing its two recognized merits, we try to locate the potential risks it poses and its application scenarios.


The stored procedure keeps user interface and business logic separate!

Today, it is a basic principle to separate user interface from business logic for application development. Different from the backstage data processing…

Image Classification With HSV Color Model Processing

Digital image processing is a discipline that studies image processing techniques. The image referred in this research is a static image form vision sensors (webcam). Mathematically, the image is a continuous function of light intensity on two-dimensional field. In order to be processed by a computer, an image should be presented numerically with discrete values. A digital image can be represented by a two-dimensional matrix f (x, y) consisting of M columns and N rows. In color image…

Non-traditional strategies for mid-career switch to #Datascience and #AI

In this post, I explore strategies to switch to Data Science mid-career. This switch is not easy, but based on the experience of many who I have taught/mentored/recruited – it is possible. Most people consider PhD/MooC etc for switching their career to Data Science. But here, I will explore some non-traditional/unorthodox ways of switching to Data Science. I draw upon my personal experience as a teacher, data…

The Power and Cost of Hurricanes

Every year, late in the summer, waves of warm air come off the African continent and enter into the warm open seas of the mid-Atlantic Ocean. When the conditions are right, these waves of warm air form into tropical depressions. Tropical depressions can then turn into a tropical storm, which is when the storms are given a human moniker thus becoming an official “named storm." After that they can become hurricanes of varying intensity and…

A framework for automated rating of online reviews against the underlying topics

Even though the most online review systems offer star rating in addition to free text reviews, this only applies to the overall review. However, different users may have different preferences in relation to different aspects of a product or a service and may struggle to extract relevant information from a massive amount of consumer reviews available online. In this paper, we present a framework for extracting prevalent topics from online reviews and automatically rating them on a 5-star…

Building your first Machine Learning model on iPhone

This tutorial will teach you how to build a ML model on iPhone using CorelML. Interestingly this is not the first time that Apple has come out with a framework for machine learning on its devices. Last year it launched a bunch of libraries for the same:

  1. Accelerate and Basic Neural Network Subroutines (BNNS) – Efficiently utilize CPU for predictions using Convolutional Neural Networks.
  2. Metal Performance Shaders CNN…
