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

.NET for Apache Spark 0.11.0 docker image

My .NET for Apache Spark v0.11.0 docker image is now available

.NET for Apache Spark 0.11.0 is now available and I have also updated my related docker images for Linux and Windows on the docker hub.

If you are interested, check out the official resources, or one of the following articles.

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,

htm.core parameters – Single Order Sequence Memory

To allow the htm.core temporal memory to learn sequences effectively, it is import to understand the impact of the different parameters in more detail.

In this part I will introduce

  • columnDimensions
  • cellsPerColumn
  • maxSegmentsPerCell
  • maxSynapsesPerSegment
  • initialPermanence
  • connectedPermanence
  • permanenceIncrement
  • predictedSegmentDecrement

Temporal Memory – Previously on this blog…

Part 1 just covered enough basics of htm.core to get us started, and we actually saw how the single order memory got trained.
A cycle of encoded increasing numbers from 0 to 9 was very easy to predict, as there was always just one specific value that could follow the … more
