For example, clustering algorithms can group similar images together, while association rules can discover how different items are related in market basket analysis.
Unsupervised learning is valuable because it can reveal hidden structures in large data sets that may not be apparent through supervised methods. It is particularly beneficial in cases where labeled data is scarce or unavailable. However, its main challenge lies in the interpretation of the results, as the outcomes may not always align with human understanding.
Reinforcement Learning
Reinforcement learning is a methodology inspired by behavioral psychology. In this approach, an agent learns to make decisions by taking actions in an environment to achieve a reward. The agent receives feedback from the environment based on its actions and adjusts its strategies accordingly. This can be visualized through the example of a robot learning to navigate a maze, where it receives positive reinforcement for reaching the end and negative reinforcement for hitting walls.
The key aspects of reinforcement learning include the agent, the environment, actions, states, and rewards. The architecture of the network often incorporates techniques such as Q-learning or policy gradients. One significant advantage of reinforcement learning is its applicability to complex decision-making scenarios, such as game playing or robotic control. Nonetheless, it encounters challenges like the requirement for substantial computational resources and potentially lengthy training times.
