Unsupervised Learning
Unlike supervised learning, unsupervised learning does not require labeled data for training. Instead, it focuses on discovering patterns, relationships, or structures within the data on its own. This type of AI is particularly useful when dealing with large datasets where manually labeling the data would be time-consuming or impractical. Unsupervised learning techniques, such as clustering and dimensionality reduction, can be applied to various domains, including customer segmentation, anomaly detection, and recommendation systems.
Reinforcement Learning
Reinforcement learning is a type of AI that involves an agent learning to make decisions by interacting with an environment. It operates under a reward-based system, where the agent receives positive or negative feedback based on its actions. The goal of reinforcement learning is to maximize the cumulative reward over time, and the agent learns to take actions that lead to desirable outcomes while avoiding unfavorable ones. This type of AI is commonly applied in robotics, game playing (such as AlphaGo), and autonomous vehicle control.
