What it is
Deep learning is a specialized branch of machine learning that employs neural networks with many hidden layers, often referred to as "deep" neural networks. These architectures allow models to automatically discover and learn hierarchical representations of data, extracting increasingly abstract features from raw inputs like images, sound, or text. This capability enables deep learning systems to achieve high performance on complex tasks that were previously challenging for traditional machine learning methods.
Deep learning is frequently in the news as the driving force behind breakthroughs in generative AI, computer vision, and natural language processing. Its success relies heavily on vast amounts of data and significant computational power, often requiring specialized GPUs. Investors follow news about companies developing or implementing deep learning solutions, as these advancements can lead to disruptive technologies, from autonomous vehicles to highly sophisticated chatbots and AI-powered search engines.
Why it matters
Deep learning powers the most advanced AI applications, influencing technological progress and the market value of companies at the forefront of AI.
