Supervised learning is a ML technique where a model learns from labeled data to make predictions or decisions. This is particularly useful when you have a target variable that you want to predict based on input features. One interesting application of supervised learning is spam classification, where the model is trained to categorize emails as spam or not spam based on past examples.
| Algorithm | Description |
|---|---|
| Linear Regression | Fits a line to the data points, predicting a continuous value. |
| Logistic Regression | Estimates the probability of a binary outcome using logistic function. |
| Decision Trees | Creates tree-like models to make decisions based on feature values. |
Exploring different types of supervised learning algorithms allows you to choose the best approach for your specific problem.
In contrast, unsupervised learning deals with unlabeled data. The goal is to discover hidden structures or patterns in the data without any predefined output variable. Dimensionality reduction, anomaly detection, and clustering are common unsupervised learning techniques. An interesting application is customer segmentation, where you group customers based on similar behaviors or preferences.
| Algorithm | Description |
|---|---|
| K-means Clustering | Divides the data into non-overlapping clusters based on similarity. |
| Principal Component Analysis (PCA) | Reduces the dimensionality of high-dimensional data while preserving most of the information. |
| Autoencoders | Learn efficient data representations by compressing and reconstructing input data. |
Unsupervised learning algorithms are powerful tools for discovering hidden patterns in your data.
Throughout the course, you’ll work on various projects that apply ML techniques to real-world problems. These projects will help solidify your understanding of the material and give you practical experience in building ML models. By the end of the course, you’ll be equipped with the knowledge and skills to tackle ML problems and make informed decisions.
