Confidence Intervals Without Pain

We propose a simple model-free solution to compute any confidence interval and to extrapolate these intervals beyond the observations available in your data set. In addition we propose a mechanism  to sharpen the confidence intervals, to reduce their width by an order of magnitude. The methodology works with any estimator (mean, median, variance, quantile, correlation and so on) even when the data set violates the classical requirements necessary to make traditional statistical techniques…

Where Do We Stand With GANs?

Summary:  GANs (Generative Adversarial Nets) originally thought to be a tool for inexpensively creating DNN training data have instead become the tools for creating deep fake images.  However the deep fake technology is now finding uses in the commercial world and promises valuable results.

 

Generative…

Smart Manufacturing and What It Means to Win the 1% Race

I had the great fortune to sit on an Ericsson-Wired Magazine panel with some outstanding thought leaders to debate the ramifications of the Fourth Industrial Revolution.  We debated whether the era was a revolution or just an evolution (I argued revolution because it will force organizations to think differently about their business and operational models) and whether IoT had failed so far (I said that to date it had “under-performed” from a business value…

3 Types of Machine Learning in AI

When we look at broadly different kinds of Machine Learning that are used in practice in Artificial Intelligence

Historically, there have been several approaches in Machine learning for AI like supervised learning, unsupervised learning, reinforcement learning, case-based reasoning, inductive logic programming, experience based generalisation etc. there have been several examples of waves of machine learning for different AI problems. But, of them the 3 most important categories of…

Artificial Intelligence Continues Where Analytics Ends?

AI is a new buzzword but there has been a lot of talk around analytics and prospects over a decade. Here we present a perspective that AI is a continuum of Analytics

Let us see how...

Different approaches in Data Science and analytics have been originated in the field of statistics.

AI has emerged on the other hand out of computer science as a practice and science of studying "intelligent agents". 

The way is to treat AI as extending conventional analytics with a…

13 Applied Artificial Intelligence & Internet of Things Industrial Use Cases in Retail Industry

"We used computer vision, deep learning algorithms and sensor fusion, much like you’d find in self-driving cars. We call it -Just Walk Out’ technology"

-Amazon

Much to the surprise of everyone in the retail industry, Amazon launched a new format of stores called "Amazon Go." The most interesting feature of these stores is that shoppers will not have to check out at a counter with a clerk or even with an automated kiosk. Shoppers simply have to swipe into the store with an app,…

Re-sampling: Amazing Results and Applications

This crash course features a new fundamental statistics theorem -- even more important than the central limit theorem -- and a new set of statistical rules and recipes. We discuss concepts related to determining the optimum sample size, the optimum k in k-fold cross-validation, bootstrapping, new re-sampling techniques, simulations, tests of hypotheses, confidence intervals, and statistical inference using a unified, robust, simple approach with easy formulas, efficient…

The story of Big Data, Data Science & Data Mining

We live in a world where the amount of data has increased on a large scale in various fields. Websites track user activities, marketers collect the customer’s purchasing history, so-called “Quantified-Selfers” collect the user’s sleeping patterns and heart rates, and so on.

With the availability of vast amounts of data, most industries have started focusing on leveraging valuable insights from it. Those insights can give businesses a competitive advantage in the market and…

Deconstructing the Concept of Efficiency

The concept of efficiency is not always easy to grasp.  People go to work.  They do their job.  They follow the pace.  What exactly is efficiency in the scheme of things?  I think it is important to be able to distinguish between how hard different workers are working.  It is not really possible to discuss efficiency if this kind of comparison is not performed.  Improving efficiency is about getting more from a person or process.  Therefore in order to determine whether or not efficiencies…

Extracting knowledge from knowledge graphs using Facebook Pytorch BigGraph.

Machine learning gives us the ability to train a model, which can convert data rows into labels in such a way that similar data rows are mapped to similar or the same label.

For example, we are building SPAM filter for email…
