NumSharp Cheat Sheet

NumPy to NumSharp Cheat Sheet

Recently, I published a small example project to utilize the htm.core AI algorithm by consuming its REST API via C#. As the API also transfers serialized multi-dimensional NumPy arrays, I was looking for an easy way to get them back into C# objects. I’ve tried out a couple of approaches and finally decided on using the NumSharp library, as I wanted a solution that works on multiple platforms.

I find DataCamps’ Data Science Cheat Sheets very useful and was hoping to find something similar for NumSharp. Well, I didn’t, but obviously that gave me a … more

htm.core and C#

In case you weren’t aware, htm.core now also provides a REST interface to it’s Network API. With this in place, it is possible to utilize the built-in encoders, Spatial Pooler and Temporal Memory from almost any programming language. In this post I briefly want to touch on how to use htm.core and C# together.

Introduction

Before you can start playing around with the REST interface, you will need to have the example REST server running.

To do that, you can either

  • download the source and build it yourself. Once built, the server executable (rest_server) should

.NET for Apache Spark Docker Image available on GitHub

.NET for Apache Spark Docker Image available on GitHub

I am really honored by the fact, that a lot of people seem to use my .NET for Apache Spark docker image to explore how C# and Apache Spark can work together, for example.

Additionally, I am getting a lot of request lately, asking whether I would be willing to share the code for creating the images.

And finally, after tidying it up a bit (e.g. removing the experimental Windows support), it is now available on GitHub.

So thanks to everyone who made this image such a success and of course you are very welcome to … more

htm.core parameters – High Order Sequence Memory

In part 2, I used htm.core as a single order sequence memory by allowing only one cell per mini-column. In this post I’ll finally have a first look at the high order sequence memory.

Before we do that, I want to show you one last single order memory example however.

Single Order Sequence Memory Recap

As you might remember from the last post, these were the settings for our htm.core temporal memory (aka sequence memory).

    columns = 8
    inputSDR = SDR( columns )
    cellsPerColumn = 1
    tm = TM(columnDimensions          = (inputSDR.size,),
            cellsPerColumn            = cellsPerColumn,
