Nowadays, with the rise in sensor technology, the amount of spatial and temporal data increases day by day. Fast, effective, and accurate analysis and prediction of collected data have become more essential than ever. Spatial Online Analytical Processing (SOLAP) emerged to perform data mining on spatial and temporal data that naturally contains the hierarchical structure used in many complex applications. In addition, uncertainty and fuzziness are inherently essential elements of data in many complex data applications, particularly in spatial-temporal database applications. In this study, FSOLAP is proposed as a new fuzzy SOLAP-based framework to compose the benefits of fuzzy logic and SOLAP concepts and is extended with inference capability to the framework to support predictive analytics. The predictive accuracy and resource utilization performance of FSOLAP are compared using real data with some well-known machine learning techniques such as Support Vector Machine, Random Forest, and Fuzzy Random Forest. The extensive experimental results show that the FSOLAP framework for the predictive analytics of various spatiotemporal events in big meteorological databases is considerably more accurate and scalable than using conventional machine learning techniques.

Modeling and Querying Fuzzy SOLAP-Based Framework Keskin, Sinan; Yazıcı, Adnan (2022-03-01) Nowadays, with the rise of sensor technology, the amount of spatial and temporal data is increasing day by day. Modeling data in a structured way and performing effective and efficient complex queries has become more essential than ever. Online analytical processing (OLAP), developed for this purpose, provides appropriate data structures and supports querying multidimensional numeric and alphanumeric data. However, uncertainty and fuzziness are inherent in the data in many complex database applications, esp...
FMDBMS - a fuzzy MPEG-7 database management system Erçin, Nazif İlker; Yazıcı, Adnan; Department of Computer Engineering (2012) Continuous progress in multimedia research in recent years have led to proliferation of their applications in everyday life. The ever-growing demand in high performance multimedia applications creates the need for new and efficient storage and retrieval techniques. There exist numerous studies in the literature attempting to describe the content of these multimedia documents. Moving Picture Experts Group’s XML based MPEG-7 is one of these studies that makes it possible to describe multimedia content in term...
Association rule mining using fuzzy spatial data cubes Isik, Narin; Yazıcı, Adnan (2006-07-01) The popularity of spatial databases increases since the amount of the spatial data that need to be handled has increased by the use of digital maps, images from satellites, video cameras, medical equipment, sensor networks, etc. Spatial data are difficult to examine and extract interesting knowledge; hence, applications that assist decision-making about spatial data like weather forecasting, traffic supervision, mobile communication, etc. have been introduced. In this thesis, more natural and precise knowle...
MOFCA: Multi-objective fuzzy clustering algorithm for wireless sensor networks SERT, SEYYİT ALPER; Bagci, Hakan; Yazıcı, Adnan (2015-05-01) This study introduces a new clustering approach which is not only energy-efficient but also distribution-independent for wireless sensor networks (WSNs). Clustering is used as a means of efficient data gathering technique in terms of energy consumption. In clustered networks, each node transmits acquired data to a cluster-head which the nodes belong to. After a cluster-head collects all the data from all member nodes, it transmits the data to the base station (sink) either in a compressed or uncompressed ma...
