6.4 Supervised and Unsupervised Algorithms
As stated in the previous chapter, Data Science uses various algorithms to find patterns, make predictions, or analyze large data. Choosing the right algorithm depends on the type of data and the kind of problem you are trying to solve.
Some common data science algorithms are:
- Linear Regression: Predicts future values based on a straight-line relationship (e.g., predicting student scores from study hours).
- Decision Trees: Uses a tree-like model to make decisions based on yes/no questions (e.g., predicting if a customer will buy or not).
- K-Means (Clustering): Groups similar items together (e.g., grouping students with similar interests).
These algorithms help organizations solve real-world problems such as predicting exam results, grouping customers for better marketing, and identifying patterns in fraud or health data.
