Artificial intelligence (AI), machine learning (ML), neural networks (NNs), and deep learning (DL) are related technologies transforming marketing. AI is the overarching concept of machines mimicking human intelligence, while ML is a subset allowing computers to learn from data. NNs, inspired by the human brain, are a type of ML model used for pattern recognition, and DL is an advanced form of NNs that excels at analyzing large, unstructured datasets. These technologies enable various marketing applications, including personalized recommendations, chatbots, predictive analytics, and ad optimization. Understanding these concepts is crucial for marketers to leverage AI-powered tools for improved customer experiences, advertising efficiency, and brand loyalty.
