10 Popular Machine Learning Algorithms to Know in 2024

One of the buzzwords now circulating in the IT business is machine learning. It is being used in increasingly typical situations, such as when Amazon suggests things that match well with a product you've already bought or when it suggests related films after you watch videos in a specific genre. Not just these, but numerous other instances genuinely make the most of its potential. Popular Machine Learning Algorithms like linear regression and decision trees are fundamental tools for predictive analytics.

In these highly dynamic times, a wide variety of machine learning algorithms have been developed to assist in resolving challenging situations in the real world. In this article, You'll learn about 10 popular machine-learning algorithms and the many learning techniques used to transform machine-learning algorithms into useful machine-learning models.

1. Linear Regression

Linear regression is a powerful statistical method for continuous data prediction. It models the relationship between a scalar response and one or more explanatory factors. When you have just one explanatory variable, it's termed simple linear regression. However, in situations where multiple variables influence the response, multiple linear regression is employed.

2. Logistic Regression

A classification algorithm for binary and multiclass classification problems is logistic regression. The logistic model in statistics is a statistical model that depicts the likelihood that an event will occur by making the event's log odds a linear combination of one or more independent variables. In regression analysis, logistic regression is used to estimate a logistic model's parameters. Mastering Popular Machine Learning Algorithms is essential for advancing in the field of artificial intelligence and data science.

3. Decision Trees:

A tree-based model, known as a decision tree, utilizes a tree structure to depict decisions and their probable outcomes, serving as a valuable tool in both classification and regression tasks. This decision support technique employs a tree-like structure to portray various options and their associated potential outcomes, encompassing factors such as utility, resource costs, and the probabilities of chance events.

4. Random Forest:

A decision tree extension that employs numerous decision trees to lower overfitting and boost prediction accuracy. A large number of decision trees are built during the training phase of the random forests or random decision forests ensemble learning approach, which is used for classification, regression, and other tasks. Implementing machine learning algorithms in 2024, such as regression and clustering, will help businesses derive valuable insights from their data.

5. K-Nearest Neighbours (KNN):

This non-parametric classification and regression algorithm bases its prediction on the average of the K data points that are closest to it. The k-nearest neighbors approach is a non-parametric supervised learning technique in statistics that was first created in 1951 by Evelyn Fix and Joseph Hodges and then improved by Thomas Cover. Regression and classification are two uses for it.

6. Support Vector Machines (SVM):

A powerful technique for issues including regression, classification, and outlier detection. Hyperplanes are used to categorize data points. Support vector machines are supervised learning models with related learning algorithms used in machine learning to examine data for regression and classification. It is one of the 10 Popular Machine Learning Algorithms.

7. Naive Bayes:

The naive Bayes classifier, a probabilistic classification algorithm, excels in high-dimensional scenarios with limited data. It belongs to the family of probabilistic classifiers based on Bayes' theorem, assuming strong feature independence. Despite its simplicity within Bayesian network models, naive Bayes can achieve high accuracy when combined with kernel density estimation.

8. Gradient Boosting and AdaBoost:

Gradient boosting is a versatile machine-learning technique utilized for both classification and regression tasks. It creates a prediction model using an ensemble of decision trees, typically weak learners. In 1995, Yoav Freund and Robert Schapire introduced AdaBoost, a statistical classification meta-algorithm. AdaBoost's effectiveness can be further improved by integrating it with various other learning methods, enhancing its predictive capabilities.

9. Convolutional Neural Networks (CNNs):

 This deep learning technique is a type that is frequently employed in speech recognition, image classification, and computer vision issues. Convolutional neural networks are a type of artificial neural network used most frequently in deep learning to evaluate visual data.

10. Recurrent Neural Networks (RNNs):

A subset of deep learning algorithms that excels at handling sequential data, including time series, speech recognition, and natural language processing. The output from some nodes can influence subsequent input to the same nodes in a recurrent neural network, which belongs to a family of artificial neural networks where connections between nodes can establish a cycle.
