Top 10 machine Learning algorithms for beginners 👇👇 1. Linear Regression: A simple algorithm used for predicting a continuous value based on one or more input features. 2. Logistic Regression: Used for binary classification problems, where the output is a binary value (0 or 1). 3. Decision Trees: A versatile algorithm that can be used for both classification and regression tasks, based on a tree-like structure of decisions. 4. Random Forest: An ensemble learning method that combines multiple decision trees to improve the accuracy and robustness of the model. 5. Support Vector Machines (SVM): Used for both classification and regression tasks, with the goal of finding the hyperplane that best separates the classes. 6. K-Nearest Neighbors (KNN): A simple algorithm that classifies a new data point based on the majority class of its k nearest neighbors in the feature space. 7. Naive Bayes: A probabilistic algorithm based on Bayes' theorem that is commonly used for text classification and spam filtering. 8. K-Means Clustering: An unsupervised learning algorithm used for clustering data points into k distinct groups based on similarity. 9. Principal Component Analysis (PCA): A dimensionality reduction technique used to reduce the number of features in a dataset while preserving the most important information. 10. Gradient Boosting Machines (GBM): An ensemble learning method that builds a series of weak learners to create a strong predictive model through iterative optimization.
