Understanding the Differences
In the realm of machine learning, there are two primary types of techniques used: supervised learning and unsupervised learning. Each has its own strengths and applications.
Supervised Learning
Supervised learning involves training a model on a labeled dataset, meaning that each training example is paired with an output label. The goal is for the model to predict the output for new data accurately. Common algorithms include decision trees, support vector machines, and neural networks.
Unsupervised Learning
In contrast, unsupervised learning deals with unlabeled data, aiming to find hidden patterns or intrinsic structures. Algorithms such as k-means clustering and principal component analysis fall into this category.
Applications and Use Cases
📈 Supervised learning is widely used for tasks like spam detection, sentiment analysis, and medical diagnosis where the outcome is known and labeled data is available.
🔍 Unsupervised learning is helpful in exploratory analysis, customer segmentation, and anomaly detection, where labels are not available.
