Rough sets on fuzzy approximation spaces and applications to distributed knowledge systems
DOI: 10.1504/IJAISC.2008.021260 | D.P. Acharjya, B.K. Tripathy | A fuzzy relation is an extension of crisp relation on any set U. Fuzzy proximity relations on U are much more general and abundant than equivalence relations. The fuzzy approximation space which depends upon a fuzzy proximity relation defin... | 1 - 14 |
A hierarchical fuzzy system with high input dimensions for forecasting foreign exchange rates
DOI: 10.1504/IJAISC.2008.021260 | France Cheong | Fuzzy systems suffer from the curse of dimensionality as the number of rules increases exponentially with the number of input dimensions. Although several methods have been proposed for eliminating the combinatorial rule explosion, none of ... | 15 - 24 |
Local reweight wrapper for the problem of imbalance
DOI: 10.1504/IJAISC.2008.021260 | S.B. Kotsiantis | Many real-world data sets exhibit skewed class distributions in which the classes are not approximately equally represented. Traditional machine learning algorithms can be biased towards majority class due to over-prevalence. This paper fir... | 25 - 38 |
Learning to classify threatening e-mail
DOI: 10.1504/IJAISC.2008.021260 | S. Appavu alias Balamurugan, R. Rajaram | In this paper we study supervised classification of e-mails. We consider the task of Threaten E-mail Detection (i.e., e-mail related to terrorism, fraud, etc.). In this supervised learning setting, we investigate the use of Data Mining clas... | 39 - 51 |
Artificial Intelligence technique for modelling and forecasting of solar radiation data: a review
DOI: 10.1504/IJAISC.2008.021260 | Adel Mellit | Artificial Intelligence (AI) has been used and applied in different sectors, such as engineering, economic, medicine, military, marine, etc. AI has also been applied for modelling, identification, optimisation, prediction, forecasting, and ... | 52 - 76 |
Detection of hard cuts and gradual transitions from video using fuzzy logic
DOI: 10.1504/IJAISC.2008.021260 | S. Das, S. Sural, A.K. Majumdar | In this paper, we introduce a novel approach for the detection and classification of shot boundaries based on interval type-2 fuzzy logic. We consider fuzzy low level features (Fuzzy Histogram (FH) and Fuzzy Co-occurrence Matrix (FCM)) and ... | 77 - 98 |
Formal specification and validation of multi-agent behaviour using TLA+ and TLC model checker
DOI: 10.1504/IJAISC.2008.021260 | Toufik Taibi | This work views agent coordination from a purely behavioural viewpoint. We use the Temporal Logic of Actions (TLA) to formally specify the behaviour of individual agents as well as the behaviour of a coalition of agents by composing the beh... | 99 - 113 |
Reliability forecasting by recurrent Support Vector Regression
DOI: 10.1504/IJAISC.2008.021260 | Wei-Chiang Hong, Chien-Yuan Lai | Support Vector Regression (SVR), which employs the structural risk minimisation principle to minimise an upper bound of the generalisation errors instead of minimising the training errors used by ANNs, has been successfully applied to solve... | 114 - 129 |
Physical time series prediction using Recurrent Pi-Sigma Neural Networks
DOI: 10.1504/IJAISC.2008.021260 | Abir Jaafar Hussain, Panos Liatsis, Hissam Tawfik, Atulya K. Nagar, Dhiya Al-Jumeily | This paper presents a new type of recurrent neural network, called the Recurrent Pi-Sigma Neural Network (RPSN) and its application to physical time series prediction. The network is constructed of two layers, the sigma and the pi unit laye... | 130 - 145 |
