====AI Types====

There are three basic types of AI that Cognition can create for you.

===State AIs===

A **State** AI is one that determines the //instantaneous state// of an asset or assets.

It can't capture things happening over time, but at any one moment it can tell you if the asset is in a particular state.

There are two sub-types of state AI - the [[support vector machines|Support Vector Machine]] which works like a //check engine// light for an asset, letting you know if there's a general problem, or a [[neural network|Neural Network]] which can learn to recognise specific asset states.

===Event AIs===

Event AIs detect events happening over time.

These are generally [[neural network|Neural Networks]].

Each event-detecting AI works over a fixed window of time, at a fixed resolution. For example, the default event detecting AI works over 10 seconds, at a resolution of one-sample-per-second. However, it's possible to create AIs that work over a much larger time-frame with a coarser resolution, when required.

===Model AIs===

Model AIs produce values to calculate expected results.

These are generally [[neural network|Neural Networks]].

These are used in two key scenarios...

   * To produce a 'model' value  that you can compare against, to indicate when an asset has output that is not expected, or
   * To produce a value that is only indirectly measured and has no known formula, based on manual readings.
