Likes
Machine Learning is one of the hottest skills in our top 10 skills list in today tech world. You can add this to your skill-set irrespective if you want a career in Data Science or AI, as you need to understand the core machine learning algorithms.
In this tutorial, we show the ten machine learning algorithms that every beginner should know — in simple English!
Top 10 Machine Learning Algorithms

🔟 Top 10 Machine Learning Algorithms

1. Linear Regression

Linear Regression: One of the simplest algorithms for predicting continuous values.

👉 For example, using area and location to predict house prices.

2. Logistic Regression

Logistic Regression — Despite its name, it is kind of used for classification problems.

👉 For example, spam or not spam prediction from an email.

3. Decision Tree

A Decision Tree is a flowchart-like structure that splits data into branches to enable decisions based on conditions.

👉 E.G.: Loan: Given if income=?, age=? and credit score=?

4. Random Forest

Random Forest is an ensemble model that combines various decision trees to increase accuracy.

👉 Example: Customer churn prediction.

5. Support Vector Machine (SVM)

Support vector machines (SVMs) are used to search for the best decision boundary between classes.

👉 Example: Image classification or Face Detection

6. K-Nearest Neighbors (KNN)

KNN is a model that classifies data points based on their nearest neighbours.

☝🏻 For example, if you are going to sell a product that depends on a category.

7. Naive Bayes

Naive Bayes is a probabilistic method adapted to the conditions of text classification.

For example, a spam filter in emails.

8. K-Means Clustering

K-Means Grouping Algorithm to Cluster Similar Data Points (Classification Work without Label Markups)

👉 Example: Market segmentation in marketing.

9. Principal Component Analysis (PCA)

Instead, PCA is used when you have a high number of features that need to be reduced while retaining crucial information.

👉 Example: Visualisation data + noise removal.

10. Gradient Boosting (XGBoost)

A strong ensemble model created by combining weak learners.

👉 For example, Fraud detection and ranking systems
