We have rolled out a new update, (1.0)/3.4 which contains a number of bug fixes and some new features. The update will be automatically downloaded and installed when you start Synapse (provided that you are connected to the internet)
New features:
- The new Updater2 update engine with an improved versioning system, download system and support for a more advanced release structure.
- Improved CSV input format that provides more features for handling string data (enumeration and removal in addition to the existing expansion):
- Generalized Hebbian Algorithm (GHA) update rule. A new Hebbian type update rule that performs PCA. The difference between it and Oja’s rule is that GHA results in sorted principal components.
- Splash screen, minor improvement with verbose loading of plugins
- Start screen, some visual improvements
- Two more plot line styles and marker support added to the Scatter Plot:
- Data embedded in solution is now compressed
Bug fixes:
- Component GUI flicker fixed
- Select Filter inadvertent sort fixed
- Hebbian component GUI refresh in training fixed
- Script Filter, disconnected GUI elements removed
- Unstage (scaling) in the Sink component fixed
- Column resize in GridView enabled
Synapse, Updates
One of the most under-appreciated types of adaptive system are the ones that use Hebbian learning. It is because of their simplicity that they get ignored, but as we shall show, they do have some practical applications for which they are really good. In Synapse Hebbian learning is embodied by the Hebbian Layer component and the Hebbian and Oja’s update rules.

Synapse, Theory
The fourth tutorial, “The Cows of Navarone”, in the Synapse tutorial series has been published. It covers the use of visualizers for creating local filters, how to create user snippets, how to trace errors back to source data using the Error Analyzer, how to real-time test systems using the Probe and how to make a qualitative analysis of a system using sensitivity analysis.
The tutorial assumes that the three previous tutorials have been completed and the material understood.
Excerpt from the tutorial intro:
“Greece and the islands of the Aegean Sea have given birth to many myths and legends of war and agriculture. And those once-proud stones, of ruined and shattered temples bear witness to the civilization that flourished and then died here and to the demigods and heroes who inspired those legends on this land and these islands. But, though the stage is the same, ours is a legend of our own times, and its heroes are not demigods, but the people form the National Statistical Service of Greece.
In the last decade of the 20th century, so the story goes, people from NSSG collected agricultural data in the rural parts of the Greek mainland and islands. Their goal is said to be collecting background data for a new taxation model. Truth be told, we may never know as the full description has been lost in the vast regions of the public domain. The written records of the data however remain, and we shall use them to model the presence on these lands of the bovine creatures named ”The Cows of Navarone”.
The data contains a number of variables measured at different villages in Greece. Each sample represents one village. One of these variables is the number of cows in the village, and this is the one we will try to model, given the other variables.“
