Abstract
A new data world which never get deformed, can be reached from anywhere, continuously stream and multiply, emerged with the evolution of technology. The data, in particular, created by business firms, scientific research centers, and automation systems reached great amounts. It has become the main target of many data analysts to reach meaningful, unexplored, and valuable information or deductions among these piles of data. In this chapter, firstly the techniques of artificial intelligence and the skills of these techniques were discussed. Later, the mostly-used techniques in the finance sector, the advantages and weaknesses of these techniques, and the methods which can be used to process the data created by the finance sector, which creates big data and is one of the leading sources, was comparatively shown. The current version of the mostly-used artificial intelligence methods in the finance sector was scanned and the new skills and contributions it provides to the sector were examined. What Classification, clustering, association rules, and time series analysis methods, in particular, cover and what problems they can produce solutions to were examined and the readers were informed about these techniques. It was aimed to give information about forming credit score and customer segmentation, where classification and clustering methods are especially employed, with sample studies. It was aimed to present the principles the up-to-date methods are based on and their theoretical and practical applications in a meaningful way. In addition to these, information about practical and useful software that can be used for data analysis in the finance sector was given and the skills of this software were conveyed to the readers. Finally, how the techniques of processing big data can be used was examined through samples as the finance data are classified as big data. The difficulties met during the analysis of big data, a natural result created by this sector, and solutions to them were presented. Updated big data processing solutions like Hadoop, Spark, MapReduce, Distributed computing, and GPU (Graphics Processing Unit) computing, in particular, were comparatively explained. The main principles that big data processing techniques are based on were simplified in a way that the readers could understand and were supported by examples from the sector. Especially, Spark, Hadoop, and MapReduce methods, which are leading methods in processing big data, were examined. Finally, the contributions made to the sector by artificial intelligence and big data processing techniques were generally summarized and the results were presented.
