This “general purpose” learning ability sets DeepMind’s AI apart from narrow AI designed for specific tasks.
• AlphaGo and successors – DeepMind’s AlphaGo program beat world champions at the complex board game Go, a feat thought nearly impossible for AI just years earlier. Follow-up programs like AlphaZero and MuZero achieved similar dominance through entirely self-taught reinforcement learning.
• Protein folding – DeepMind’s AlphaFold AI system predicts protein structures with accuracy comparable to laboratory methods, a major breakthrough in biology. In 2022, AlphaFold’s protein database expanded to cover virtually every known protein, over 200 million structures.
• WaveNet – DeepMind pioneered WaveNet, a revolutionary text-to-speech system that produces far more natural-sounding voices compared to previous speech synthesis methods. WaveNet powers assistant voices for Google, DeepMind and other companies.
• Gato – Gato is DeepMind’s “generalist agent” capable of performing over 600 tasks across vision, language and robotics with a single AI system, displaying more broadly capable intelligence.
• Healthcare – DeepMind partnered with hospitals and health organizations to apply its AI to improving patient care and medical research. Products include Streams for monitoring kidney disease and algorithms that can analyze medical images to detect eye disease or cancer.

How DeepMind’s AI Works

Many of DeepMind’s artificial intelligence breakthroughs rely on similar techniques and architectures:

• Deep neural networks – Like many advanced AI systems today, DeepMind’s algorithms use multi-layered neural networks that can recognize patterns and features in data like images, speech and text. The more data the networks train on, the more adept they become.
• Reinforcement learning – DeepMind’s programs excel through trial-and-error experience and rewards, similar to how animals and humans acquire skills. The AI repeatedly performs tasks while receiving feedback on its successes and failures, allowing it to strengthen effective behaviors.
• Self-play – Many DeepMind AIs are trained through self-play, competing against earlier versions of themselves without any human input or game data. This allows the AI to improve rapidly by challenging itself and learning from experience.
• Monte Carlo tree search – Some DeepMind systems like AlphaGo combine neural networks with Monte Carlo tree search, a mathematical approach to evaluating future decisions by simulating random playouts.
• Generative modeling – Models like Gato can generate new examples like images and text after training on real-world datasets, displaying creative abilities.

While the technical details get complex, the core principles behind DeepMind’s innovations involve giving neural networks flexible ways to learn from experience in order to master difficult tasks. This provides a generalizable model for creating AI with broad capabilities.
