Introduction
To start learning about machine learning it is crucial for beginners to grasp fundamental algorithms which run all prediction software including medical analysis. Multiple algorithms serve as fundamental components for creating the majority of machine learning systems.
This article explains ten fundamental machine learning algorithms with basic explanations that avoid advanced mathematical concepts.
1. Linear Regression
The algorithm functions for numerical outcome prediction. The algorithm creates a straight line which optimally matches the existing data points. The number of years worked by someone serves as a standard example to forecast their salary.
2. Decision Tree
The decision tree algorithm divides data through a sequence of questions which operate like a flowchart for both classification and regression tasks. For example: Is the person older than 50? Do they smoke? The model determines final outcomes like disease risks through patient response data.
3. Support Vector Machine (SVM)
SVM functions primarily as a method to classify items orobjects. The algorithm establishes separate classes through a boundary line that creates the biggest distance between them. The detection of spam among non-spam email communications presents itself as an out-in-the-world application of this system.
4. K-Nearest Neighbors (K-NN)
This algorithm functions both for classification purposes. The algorithm relies on 'k' neighboring data points to determine the class by referring to their majority classification. The K-NN algorithm will examine known digits to check which one matches most closely with the provided handwritten digit.
5. Logistic Regression
When dealing with yes/no or true/false problems logistic regression calculates event likelihood probabilities for binary classification tasks. The prediction of a customer purchase stands among the most common applications of this technique.

6. Naive Bayes
Naive Bayes helps perform both text classification along with spam detection functionality.The application of Bayes' Theorem happens through an independent features-based approach. The system detects spam emails by analyzing word content.
7. Random Forest
Used for: Classification and regression
The method uses numerous decision trees that combine their individual results.
Predicting loan approval depends on analyzing various aspects including income together with credit score.
8. K-Means Clustering
Data grouping occurs through this method as part of unsupervised learning practices.
The clustering method sorts data distributions into 'k' clusters using their similarity levels.
Example: Customer segmentation (grouping customers with similar behavior)
9. Gradient Boosting (XGBoost, LightGBM)
Used for: High-performance prediction models
The method develops models one after another and modifies each phase to address preceding mistakes.
Example: Winning Kaggle competitions with highly accurate prediction.
10. Neural Networks
The deep learning methodology utilizes this tool for image and voice applications and text processing duties.
The system functions by imitating the brain using layers designed from neurons.
The technology of face recognition coupled with voice assistants and medical image classification operates with this type of algorithm.
