Deep Learning.

Deep learning uses neural networks with many hidden layers—hence 'deep'—to learn representations of data at increasing levels of abstraction. A deep learning model might learn to recognise shapes, then edges, then objects, then semantic meaning, each layer building on the last.

Why Deep Learning Matters

Deep learning is the technology behind transformers, the architecture powering GPT, BERT, and virtually every major LLM. It enables search engines to understand the nuance, context, and intent of queries far beyond simple keyword matching.

Applications for Marketers

Deep learning is used in image recognition (for visual search), voice recognition (for voice search), natural language understanding (for content scoring), and predictive analytics (for campaign optimisation). It underpins the AI tools marketers use daily.
