II. Foundational Technologies and Techniques
A. Deep Learning
At the core of DeepMind’s research is deep learning, a subset of machine learning that uses artificial neural networks to enable computers to learn from data and make predictions or decisions without explicit programming. Deep learning models consist of multiple layers of interconnected nodes, with each layer processing increasingly complex patterns or representations of the input data. This hierarchical structure allows deep learning systems to learn and generalize from vast amounts of data, enabling them to perform tasks with human-like capabilities.
B. Reinforcement Learning
Reinforcement learning is another essential component of DeepMind’s research. It is a type of machine learning in which an agent learns to make decisions by interacting with an environment and receiving feedback in the form of rewards or penalties. The agent’s goal is to maximize the cumulative reward over time, which requires it to balance exploration (trying new actions) and exploitation (choosing the best-known action). Reinforcement learning has been successfully applied to a variety of complex tasks, from playing games to controlling robots.
III. Major Projects and Achievements
One of DeepMind’s most notable achievements is the development of AlphaGo, a computer program that uses deep learning and reinforcement learning to play the ancient Chinese board game Go.
