Synapse Tutorial IV Released
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."
