This review provides a broader overview of major data mining algorithms and their application in the financial market.
The article provides a comprehensive review of data mining methods in financial markets, highlighting the importance of these methods in discovering the value of data. The authors acknowledge the challenges posed by the rapid growth of data and the limitations of traditional analysis techniques. They also emphasize the significance of financial markets in modern society and the impact of financial activities on economic development.
However, there are some potential biases in this article. Firstly, it focuses mainly on machine learning methods and does not give enough attention to statistical models. Secondly, it only covers research published from 2009 to 2015, which may not reflect recent developments in this field. Thirdly, it does not explore counterarguments or potential risks associated with using data mining methods in financial markets.
The article also lacks evidence for some claims made, such as the statement that traditional statistical methods are becoming more and more inadequate for dealing with complex financial data. Additionally, while the authors mention challenges and promising issues in this research area, they do not provide a detailed analysis or discussion of these topics.
Overall, while this article provides a useful overview of data mining methods in financial markets, readers should be aware of its potential biases and limitations. Further research is needed to fully understand the benefits and risks associated with using these methods in finance.
