To help you navigate these options, we’ll cover the types of algorithms, the best-performing models, and their use cases.

Types of Machine Learning Algorithms

Machine learning algorithms are generally classified into four main types:

1. Supervised Learning Algorithms – Learn from labeled data and predict outcomes based on input features.
2. Unsupervised Learning Algorithms – Identify patterns or clusters in unlabeled data.
3. Semi-Supervised Learning Algorithms – Use both labeled and unlabeled data, ideal for scenarios where acquiring labeled data is costly.
4. Reinforcement Learning Algorithms – Learn by interacting with the environment and receiving rewards or penalties.

Each type serves different purposes, depending on the task, dataset, and objectives. Now, let’s dive into the best machine learning algorithms for 2024, each tailored to excel in various predictive tasks.
