The Difficulties Presented by High-Dimensional Data

A central use of the PolyChord tool is solving problems presented by high-dimensional data. High-dimensional data is present for many businesses in today’s world of BigData, where data has been gathered and there are many many variables. It is analysed in an attempt to create data models and formulas. If an accurate model is produced then the model can be used to make accurate future predictions. However, creating a model to fit high-dimensional data has been, until now, a notoriously difficult task.

This article by Sunil Sapra discusses the use of high-dimensional data and where it occurs in common commercial scenarios, and is a great explanation of the difficulties that come with fitting a model to high-dimensional data.

Here at PolyChord, we have been able to overcome a majority of these difficulties by using advanced Bayesian Data Science techniques. Unlike other tools, PolyChord takes an orthogonal approach using nested sampling to navigate thousands of dimensions and compute without compromises or approximation.

Confused About Neural Networks?

Though Artificial Intelligence is ingrained in everyday life, the concepts behind AI are quite complex and you may feel as though you need a PhD to understand it all. Not to fear, there are many videos to help you understand some of the basic concepts involved in AI.

One of our favorite explanations is by Dr. Mike Pound from the YouTube Channel Computerphile. Click here to watch “Neural Network that Changes Everything”

Here, Dr. Pound gives a brief introduction to neural networks using the concept of house pricing. He then explains how he utilizes the neural networks within his profession of image analysis and how neural networks are used for facial recognition.

Neural Network types, our capabilities

PolyNet can train all of these  types of neural network. This stage one neural network trainer is mostly limited by the number of connections (right now it can manage  ~O(1000s). The actual architecture doesn’t matter – all shown below will work with PolyNet-  so much as its scale of connectivity. Many neural networks in use right now fall well within these capabilities. As we develop further iterations, numbers of connections will expand.
