A Sensory-Motor Linguistic Theory for Artificial Cognitive Systems

2007 2007 IEEE 9th Workshop on Multimedia Signal Processing  
We propose a linguistic approach to model lexicon of human actions, previously learned and stored. human activity. The Human Activity Language (HAL)  ...  Kinetology, synthesis (generation) of executed action sequences from the phonology of human movement, finds basic primitives for t p human motion (segmentation) and associates them with A sens symbols  ...  In methodology and introduce a parallel learning algorithm kinetology, our goal is to identify the motor primitives to induce a grammar system representing a single action.  ...

Inferring Definite-Clause Grammars to Express Multivariate Time Series [chapter]

Gabriela Guimarães, Luís Moniz Pereira
2005 Lecture Notes in Computer Science  
This paper proposes the use of definitive-clause grammars for the induction of temporal expressions, thereby providing a more powerful framework than context-free grammars.  ...  The approach uses an adaptation of temporal ontological primitives often used in AI-systems.  ...  If no temporal relations have to be considered, for instance for the generation of a rule-based description of the primitive patterns, then Machine Learning algorithms can be used straightforwardly.  ...

Gutemberg Guerra-Filho, Yiannis Aloimonos
2012 Journal of Neurolinguistics  
Kinetology, the phonology of human movement, involves the learning of motor primitives through segmentation and symbolization.  ...  Among these aspects, we find the discovery of motor primitives used to build complex motion; the representation of complex actions in terms of these primitives; the generalization of movement concerning  ...  Kinetology, the phonology of human movement, involves the learning of motor primitives through segmentation and symbolization.  ...

2009 International Journal of Humanoid Robotics  
In this paper, we present the steps required for the construction of a praxicon, a structured lexicon of human actions, through the learning of grammar systems for human actions.  ...  Therefore, our approach was successful in both representational and learning aspects, and may serve as a tool to parse movement, learn patterns, and to generate actions.  ...  The SNPR algorithm 14 learned syntagmatic elements (sequences) and paradigmatic elements (sets) from minimal elements which are perceptual primitives (e.g. letters or phonemes).  ...

Small Human Group Detection and Event Representation Based on Cognitive Semantics

Yafeng Yin, Guang Yang, Hong Man
2013 2013 IEEE Seventh International Conference on Semantic Computing  
We proposed a novel video event representation based on cognitive semantics for small human group detection and event recognition in this paper.  ...  The induced grammar rules will then be used to parse test videos. The experimental results on the BEHAVE and Collective data set demonstrate the effectiveness of the proposed method.  ...  [6] introduced attribute grammar for event recognition and anomaly detection.  ...

The minimalist grammar of action

K. Pastra, Y. Aloimonos
2011 Philosophical Transactions of the Royal Society of London. Biological Sciences  
In this grammar, action terminals combine hierarchically into temporal sequences of actions of increasing complexity; the actions are bound with the involved tools and affected objects and are governed  ...  However, structuring action has important implications on action learning and generalization, in both human cognition research and computation.  ...  Just like we can learn filters for objects, we can also learn them for body parts, legs, arms, heads, torsos and hands.  ...
