  2. 1. Knowledge based perceptual anchoring : grounding percepts to concepts in cognitive robots

    Author : Marios Daoutis; Silvia Coradeschi; Amy Loutfi; Angelo Cangelosi; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anchoring; knowledge representation; cognitive perception; symbol grounding; common-sense information; Datavetenskap; Computer and Systems Science;

    Abstract : A successful articial cognitive agent needs to integrate its perception of the environment with reasoning and actuation. A key aspect of this integration is the perceptual-symbolic correspondence, which intends to give meaning to the concepts the agent refers to { known as Anchoring. However, perceptual representations alone (e.g. READ MORE

  5. 3. Studies in Semantic Modeling of Real-World Objects using Perceptual Anchoring

    Author : Andreas Persson; Amy Loutfi; Alessandro Saffiotti; Severin Lemaignan; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perceptual Anchoring; Semantic World Modeling; Sensor-Driven Acquisition of Data; Object Recognition; Object Classification; Symbol Grounding; Probabilistic Object Tracking;

    Abstract : Autonomous agents, situated in real-world scenarios, need to maintain consonance between the perceived world (through sensory capabilities) and their internal representation of the world in the form of symbolic knowledge. An approach for modeling such representations of objects is through the concept of perceptual anchoring, which, by definition, handles the problem of creating and maintaining, in time and space, the correspondence between symbols and sensor data that refer to the same physical object in the external world.

  6. 4. Prior knowledge and present events in the brain

    Author : Katrina Carlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Anticipation; prediction; predictability; attention; emotion; pain; tickle; fear; conscious; unconscious; awareness; amygdala; insula; functional magnetic resonance imaging fMRI ; positron emission tomography PET ;

    Abstract : Our experience the world is dependent on both the surroundings and the brain. In other words, perception is a synthesis of incoming signals, internal state, and previous knowledge rather than a mere reflection of the environment. READ MORE

  7. 5. Knowledge Representation, Heuristics, and Awareness in Artificial Grammar Learning

    Author : Tobias Johansson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abstraction; awareness.; non-analytic processing; Artificial grammar learning; fluency; implicit learning;

    Abstract : People can become sensitive to the general structure of different parts of the environment, often without studying that general structure directly, but through being incidentally exposed to instances that conform to the structure. When such learning proceeds unintentionally and gives rise to knowledge that is difficult to verbalize it is often referred to as implicit learning. READ MORE
