# Martin Biehl: An entities first approach to defining agents as spatiotemporal patterns

We follow a common conception of agents as individuals/entities that can act and are goal-directed. Our approach first defines spatiotemporal-patterns as the kind of structure that entities are special cases of. We then mention our proposal for a criterion which tells us which of the spatiotemporal patterns are entities.Then we continue with our definition of perceptions and action for spatiotemporal patterns which can also be used for any alternative notion of entities as long as it is based on spatiotemporal patterns. If there is some time left we will also give an example definition of goal-directedness.
The main aim of this talk is more to present the structure of a complete formal definition of agents based on spatiotemporal patterns and less the individual pieces.
