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…

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…

9 Off-the-beaten-path Statistical Science Topics with Interesting Applications

You will find here nine interesting topics that you won't learn in college classes. Most have interesting applications in business and elsewhere. They are not especially difficult, and I explain them in simple English. Yet they are not part of the traditional statistical curriculum, and even many experienced data scientists with a PhD degree have not heard about some of these concepts.

1. Random walks in one, two and three dimensions

This is a well known model,…
