COGNOIS:

Communication and Observation toward a Generic Natural Ontogeny for Intelligent Systems

The ultimate goal of COGNOIS is to develop a generic computing architecture leading to a dependable intelligent machine endowed with the required observation and communication abilities and readily amendable to various real-world applications. A major challenge in developing dependable intelligent machines exploiting extensive behavioural modeling hinges upon a fully integrated exploitation of a number of sensing modalities - optical, acoustical, mechanical, etc. - and the validation of the respective (visual, auditory, haptic, etc.) knowledge, using a variety of human-machine communication channels. Other challenges involve data selection and segmentation and knowledge representation and summarizing.

COGNOIS builds upon the “Actors-Properties-Interactions-Architecture” (APIA) which is under development in VERTEX. COGNOIS seeks ways to model general behaviours (ex. how does a human expert operator perform a delicate, dextrous task). This project focuses on a specific multimodal observation framework combining computer vision and speech recognition and integrates derived behaviours within virtual environments using advanced human-machine interfaces. The operating scenario of the COGNOIS architecture involves the following three steps:

  1. Knowledge acquisition and validation of significant entities, building on existing approaches and learning to deal with their deficiencies;

  2. Knowledge acquisition and validation of significant behaviours, stemming from known entities in the environment;

  3. Knowledge use, i.e. documentation of the observations, with the goal of developing a working prototype architecture which is first applied to situations involving a small number of simple entities and is later refined as the complexity of the observed situations is gradually increased.
