Concept Formation Taking into Account Property Relevance
نویسنده
چکیده
We propose a method to incrementally compute and use, during the concept formation, the relevance of a concept property. This relevance is computed through the account of the property correlation with other ones and it is used by the concept quality function in order to improve predictive accuracy. The proposed approach is analyzed concerning both the prediction power of the generated concepts and the time and space complexity of the concept formation algorithm. Initial results show that, in the task of prediction of values for several attributes, the proposed method has improved the prediction power of the generated concepts.

متن کاملVISCOUS NUTATION DAMPER, MODELING AND ANALYSIS
In some aerospace vehicles, the tracking sensors which act in a tracking loop as stabilizer are mounted on a two degree of freedom gyro. The gyro must align its rotor axis with the line of sight in order to remove tracking errors. The tracking precision and sensitivity are functions of the gyros performance. One of the main factors in reducing the precision and producing instabilities is nutati...

Introduction: Rural regions have experienced varied changes and social and economic reconstruction during last three decades. There exists great tendency toward functional integration between villages and cities due to increase in mobility, improvement in communication information as well as rural services. This in turn, resulted in the expansion of urban function including construction mass...
متن کاملA Generalized Framework to Consider Positive and Negative Attributes in Formal Concept Analysis
In Formal Concept Analysis the classical formal context is analized taking into account only the positive information, i.e. the presence of a property in an object. Nevertheless, the non presence of a property in an object also provides a significant knowledge which can only be partially considered with the classical approach. In this work we have modified the derivation operators to allow the ...
