Behaviour Based Knowledge Systems An epigenetic path from behaviour to knowledge A paper by Carlos Gershenson, Presented by John Evans
Introduction • Aims to bridge the gap between behaviour and knowledge based systems. • Implications for understanding of emergence of cognitive intelligence • Also holds implications for the application of these methods in future systems.
Abstraction Levels in Animal Behaviour • Vegetative – by default in order to live. • Reflex – simple immediate reaction to stimuli • Reactive – more complex reaction to stimuli • Motivated – Dependent on external stimuli and internal motivations • Reasoned – Manipulation of abstract concepts • Conscious – Anything higher, too complex to be modelled by the methods proposed
Concepts • Problem – How to abstract perception of world for manipulation and reasoning? • Generalization of perceptions or other concepts • Concepts learned from patterns and regularities • Concepts reinforced with experience • Concepts are unique to the individual as experiences differ
Epigenetic Stages to Attain Knowledge from Behaviour • 1. concept abstraction • 2. grounding of concepts though action • 3. sharing of concepts through social interactions (language) • 4. manipulation of concepts (logic) • 5. evolution of concepts (culture)
Limits of Behaviour Based Knowledge Systems • BBKS are necessarily simplifications of natural systems • Not going to produce convincing imitations of natural intelligence • More detailed analysis is described in subsequent papers
Conclusion • The paper itself is quite general • Of interest as a means of understanding emergence of knowledge • Limited potential as a means of producing intelligent systems • Nature has already produced intelligence so it makes sense to learn from it
Further Interest • The website relating to Gershenson’s work on BBKS including virtual lab http://turing.iimas.unam.mx/~cgg/cogs/keb/ • His current website at the Universidad Nacional Autónoma de México http://turing.iimas.unam.mx/~cgg/ Questions?
