High Precision Computing: Benchmark, Examples, and Tutorial

In some applications, using the standard precision in your programming language of choice, may not be enough, and can lead to disastrous errors. In some cases, you work with a library that is supposed to provide very high precision, when in fact the library in question does not work as advertised. In some cases, lack of precision results in obvious problems that are easy to spot, and in some cases, everything seems to be working fine and you are not aware that your simulations are completely…

Elman RNN implementation in Tensorflow

In this article, an implementation and explanation is given for an Elman RNN.

So… What is an Elman RNN?

Suppose you have many documents and you would like to find all names in the documents. Then one option is to use an Elman RNN! This RNN is originally invented by Jeffrey Elman . The Elman RNN reads word (and context) by word (and context) and tries to predict the label (either O if the word is not a name, B-NAME if the word is the beginning of a name and I-NAME if…

What Will Shape the Future of Machine Learning in 2018?

Any new technology is not successful until it is embraced and used to its potential. Machine learning is no exception to this rule and its success or to say its ability can be gauged by the trends that exist. Machine learning is already a hot technology at the moments and it seems to have a promising future. At present, it seems to be an evolutionary phase where remarkable developments are expected.

This brings us to the thought of what the machine learning of future…

Python libraries for Aspiring Data Scientist

Python has a unique combination of being both a capable general-purpose programming language as well as being easy to use for analytical and quantitative computing.

Python, along with R, is one of the handiest tools in a data scientist’s arsenal. It’s also one of the simplest computer languages to learn and use, primarily because most concepts can be expressed in fewer lines of code in Python, than in other languages.

Hence, beginners venturing out into the field of data…

Inside the black box

Introduction

This post is designed show the internal changes of an Artificial Neural Network (ANN/NN), it shows the outputs of the neurons from the beginning of a Backpropagation algorithm to convergence.

The hope is for a better understanding of why we use a second hidden layer, local minimums, to how many internal nodes are required and their impact on the final solution.

The Dataset…

How Biometric Authentication Works

Here is a guest post from Rowena Bonnette  on How Biometric Authentication works - 

Biometrics are the ultimate security protocol. Using security coding that is unique to each individual, you can be confident in the authenticator’s identity. We’ve seen biometric securities in science fiction movies, and we use fingerprint authentication daily on our smartphones. Now, let’s break down all of the different kinds of biometric authentication and discover how they work.…

Is Big Data Eliminating Gut Feel in Business?

Many of us trust our gut feeling implicitly.

 

We have all been there when something didn’t feel right but done it anyway. There was nothing obvious to suggest that it was a bad idea. Yet, when it turns out to be a disaster we wonder why we didn’t listen to that gentle little voice: “don’t do it.”

 

It seems that our gut feel is some magical force, but actually, it is an accumulation of thousands of tiny past moments, all informing our current situation. You could…
