This Simulator page is accessible via the following URL: https://simulator.bayesialab.com/#!simulator, or by selecting Go to Simulator in the upper right corner
This page allows you to run all publicly-available simulators. Private simulators will only be accessible if you know the respective Identifiers and Passwords.
There are two panels:
- The Input Variables Panel;
- The Output Variables Panel.
Selecting the first (blank) line closes your current simulator and loads a blank page.
Clickingbrings up information about the simulator.
Changing the state, the value, or the slider position automatically sets the variable as Observed. The corresponding evidence is set to the node in the underlying Bayesian network in order to compute the posterior probability distributions of all the other nodes.
The observation can be removed by unchecking the Observed box.
Clicking theicon (upper right corner of the page) removes all the pieces of evidence that have been set on the input variables.
If you are interested in measuring what is the impact of your observations on the output variables, you just have to select the optionavailable by clicking the icon (upper right corner of the page).
The deltas are displayed between brackets in green and red (for positive and negative impacts respectively).
With gauges, the variations are also qualitatively shown with green and red arcs (for positive and negative impacts respectively).
By default, the variations are computed with respect to the previous state. This allows to measure the impact of each piece of evidence. If you are interested in measuring the impact of a set of evidence, you can define a reference state by clicking by clicking the icon.also available
The iconallows you to store the current set of observations you have entered in a scenario file. A name can be associated with the stored set of observations.
When scenarios are available, the iconis added in the toolbar and allows you to load a set of observations that has been stored in a scenario file.
When observations are stored in a scenario file, clicking the icon allows to manage your observations:
- You can clear the stored observations to reset the scenario file,
- You can save the scenario file on your local disc,
- You can load a scenario file that is on your local disc.
When observations are stored in a scenario file, clicking theicon allows to enter into Simulation Mode
The two iconsallow to go back to the previous set of observations, and advance to the next set of observations respectively.
You can change the set of observations when you are in Simulation Mode. However you cannot store these new observations in a scenario file. You first need to quit the Simulation Mode.
Different layouts are available for each panel by clicking the icon.
