Machine learning is a subfield of artificial intelligence. It involves “training” algorithms using data, allowing systems to learn and improve from experience without being explicitly programmed for every scenario.
In machine learning, computers are fed large sets of data and algorithms that analyze the information for significant patterns. By studying these patterns, the systems learn how to carry out tasks like making predictions, classifying data points, or recognizing images.
Machine learning algorithms build mathematical models based on sample data to make predictions or decisions without being specifically programmed to perform that task. The models and predictions improve over time as the algorithm is exposed to more data.
Machine learning enables computers to solve problems dynamically without relying solely on predefined rule sets. It empowers systems to independently adapt and learn from data patterns and observations.
There are several types of machine learning algorithms:
- Supervised learning uses input data that is labeled with the desired output. The algorithm learns by comparing its predictions to the labeled examples. Common techniques include decision trees, regression analysis, and neural networks.
- Unsupervised learning examines unlabeled input data and looks for previously unknown patterns. Clustering algorithms like k-means are commonly used for unsupervised learning.
- Reinforcement learning rewards algorithms for making correct decisions. The system learns through trial-and-error interactions with a dynamic environment.
- Deep learning uses artificial neural networks modeled after the human brain. This approach can handle complex problems with massive datasets.
