Intelligent big data analytics combines big data, analytics, and artificial intelligence (AI). AI applications in data science, fintech, and marketing have significantly increased over the last five years. This has been fueled by reasons such as rising data availability in terms of volume, variety, and velocity, as well as advancements in hardware and software. AI is becoming an important business and analytic skill to alter corporate processes, reorganize workforces, optimize infrastructure, understand consumer behavior, and combine sectors. By 2021, according to Gartner, AI technology accounted for 30% of new revenue growth from industry-specific solutions. Understanding evolving consumer behavior has been a key research area for companies as they update their marketing and business strategies considering the rapid technological advancements. This Research Topic aims to present the developments in the use of AI techniques for understanding consumer behavior. There are a wide range of AI and machine learning (ML) algorithms and techniques that companies are using to understand consumer behavior. There are significant challenges in the use of AI and ML techniques for understanding consumer behavior, including selection biases, algorithmic flaws, and algorithmic unfairness that have to be investigated.
