<![CDATA[In the era of the Fourth Industrial Revolution (4IR), vast amounts of data are generated from sources such as IoT, cybersecurity, mobile, business, social media, and healthcare. Artificial intelligence (AI), particularly machine learning (ML), is essential for analyzing this data and developing smart, automated applications. Various machine learning algorithms, including supervised, unsupervised, semi-supervised, and reinforcement learning, are used to enhance application intelligence. Additionally, deep learning, a subset of ML, can process large-scale data effectively. This paper provides an overview of these algorithms and their applications across fields like cybersecurity, smart cities, healthcare, e-commerce, and agriculture. It also discusses the challenges and research opportunities in the field, aiming to be a valuable resource for both academics and industry professionals, as well as decision-makers in various real-world scenarios. Highlights: Post-modern ceramics reflect features and connotations of body language. Research explores theoretical framework, variables, and applications in ceramic sciences. Results reveal key indicators, conclusions, and supporting references. Keywords: Machine learning, Deep learning, Artificial intelligence, Data science, Data-driven decision-making, Predictive analytics, Intelligent applications]]>
