چکیده

A novel approach to interactively acquire knowledge about new objects in a logic environment is presented. When the user supplies an unknown fact containing unknown objects (constants), the system will ask interesting membership and existential queries about the objects. The answers to these questions allow the system to update its knowledge base. Two basic strategies are implemented: one that examines existing Horn-Clauses for the predicate and another one that uses types. Furthermore, a powerful heuristic, based on analogy, to pose the most interesting questions first is presented.

A learning-based control system by knowledge acquisition within constrained environment

Knowledge acquisition is important in order to build a knowledge based system. One of the methods used in acquiring knowledge is reinforcement learning. Reinforcement learning is commonly defined as a try and error style learning that occurred in episodes. This is difficult to ensure a real control object safety condition since a control object is restricted to its environmental constraints. Th...

A dialogue approach to learning object descriptions and semantic categories

Acquiring new knowledge through interactive learning mechanisms is a key ability for humanoid robots in a natural environment. Such learning mechanisms need to be performed autonomously, and through interaction with the environment or with other agents/humans. In this paper, we describe a dialogue approach and a dynamic object model for learning semantic categories, object descriptions, and new...

Ontology Based Object Learning and Recognition

This thesis deals with the problem of complex object recognition. The proposed approach takes place in the conceptual framework of cognitive vision. This thesis shows how an object categorization system is set up in three phases. The knowledge acquisition phase consists of acquiring domain knowledge as a taxonomy/partonomy of domain classes. It also consists of acquiring the visual description ...

Automatic Interpretation of UltraCam Imagery by Combination of Support Vector Machine and Knowledge-based Systems

With the development of digital sensors, an increasing number of high-resolution images are available. Interpretation of these images is not possible manually, which necessitates seeking for practical, fast and automatic solutions to solve the environmental and location-based management problems. The land cover classification using high-resolution imagery is a difficult process because of the c...

Incremental approaches for updating approximations in set-valued ordered information systems

Incremental learning is an efficient technique for knowledge discovery in a dynamic database, which enables acquiring additional knowledge from new data without forgetting prior knowledge. Rough set theory has been successfully used in information systems for classification analysis. Set-valued information systems are generalized models of single-valued information systems, which can be classif...
