| | Based on prior observations, of the variables and their temporal execution in some context, the controller's model generation function <m>P_M</m> may have captured their causal relationship in three alternative models, <m>M_1, M_2, M_3</m>, each slightly but measurably different from the others. Each can be considered a //hypothesis of the actual relationship between the included variables//, when in the context provided by <m>V_5, V_6</m>. | | | Based on prior observations, of the variables and their temporal execution in some context, the controller's model generation process <m>P_M</m> may have captured their causal relationship in three alternative models, <m>M_1, M_2, M_3</m>, each slightly but measurably different from the others. Each can be considered a //hypothesis of the actual relationship between the referenced variables//, when in the context provided by <m>V_5, V_6</m>. \\ As an example, we could have a tennis ball's direction <m>V_1</m>, speed <m>V_2</m>, and shape <m>V_3</m> that changes when it hits a wall <m>V_5</m>, according to its relative angle <m>V_6</m> to the wall. | |

| | The agent's model generation mechanisms allow it to produce models of events it sees. Here it creates models (a) <m>M_1</m> and (b) <m>M_2</m>. The usefulness / utility of these models can be tested by performing an operation on the world (c ) as prescribed by the models. (Ideally, when one wants to find on which one is best, the most efficient method is an (energy-preserving) intervention that can only leave one as the winner.) | | | The agent's model generation mechanisms allow it to produce models of events it sees.

The usefulness of these models for particular situations and goals can be tested by performing an operation on the world (c ) as prescribed by the models, through backward chaining (abduction). \\ Ideally, when one wants to find on which model is best for a particular situation (goals+environment+state), the most efficient method is an (energy-preserving) intervention that can only leave one as the winner. | |

| | The result of feedback (reinforcement) may result in the deletion, rewriting, or some other modification of the original model selected for prediction. Here the feedback has resulted in a modified model <m>M{prime}_2</m>. | | | The feedback (reinforcement) resulting from direct or indirect tests of a model may result in its deletion, rewriting, or some other modification.
