Unsupervised Learning Techniques

The Core Idea

Deep learning relies on representing data across layered feature spaces.

This allows the model to learn increasingly complex representations of the input data, ultimately leading to improved performance.

K-Means Clustering: This is arguably the most popular technique. It ai

K-Means clustering groups data points into clusters based on their similarity, aiming to minimize the distance between points within a cluster.

The user specifies the number of clusters (k) beforehand, and the algorithm iteratively assigns each point to the nearest cluster until convergence.

Frequently asked questions

What is K-Means Clustering?

K-Means clustering is an unsupervised learning algorithm that aims to partition a dataset into k distinct clusters, where each data point belongs to the cluster with the nearest mean (centroid).

What are the key differences between K-Means and DBSCAN?

K-Means requires you to specify the number of clusters beforehand, while DBSCAN automatically determines the number of clusters based on data density. DBSCAN is also better at handling noisy data.

How does Principal Component Analysis (PCA) work?

PCA identifies the principal components – axes in a dataset that capture the most variance. It then projects the data onto these components, reducing dimensionality while preserving the most important information.
