There are a few key advantages of supervised learning over unsupervised learning:
1. Labeled Data: Supervised learning algorithms are trained on labeled data, which means that the data has a clear target or outcome variable. This makes it easier for the algorithm to learn the relationship between the input and output variables.
2. Predictive Power: Supervised learning algorithms are designed to make predictions, which makes them well-suited for real-world applications. In contrast, unsupervised learning algorithms are mainly used for exploratory data analysis and pattern discovery.
3. Performance Evaluation: Supervised learning algorithms can be evaluated based on their accuracy in making predictions. This allows us to compare different algorithms and select the best one for a particular problem. In unsupervised learning, it can be more challenging to evaluate the performance of an algorithm as there is no clear target variable to measure against.
That being said, unsupervised learning also has its strengths and can be useful in certain situations where labeled data is not available or where the goal is to uncover hidden patterns in the data.
