What is machine learning? Guide, definition and examples

Machine learning (ML), a subset of artificial intelligence, revolves around systems’ ability to learn and make predictions based on data. Fundamentally, it works by using algorithms to analyze large datasets, creating models that can recognize patterns, and applying these insights to make decisions without explicit human intervention. ML’s real-world applications are expansive, ranging from personalized recommendations on streaming platforms to autonomous driving technology.

The core idea is to train models using data examples, which can be supervised (labeled data) or unsupervised (unlabeled data). A thorough understanding of ML includes familiarizing oneself with its algorithms, such as regression analysis, clustering, and neural networks. These methodologies underpin the technology’s robustness and enable applications in predictive analytics, speech recognition, and more.

Machine learning libraries expedite the development process by providing optimized algorithms, prebuilt models and other support. Learn about 10 widely used ML libraries.

Machine learning libraries are repositories packed with ready-to-use tools and functionalities that provide scalable solutions for building ML models. By integrating these libraries into projects, developers can save crucial time and resources instead of developing algorithms from scratch. Popular libraries like TensorFlow and PyTorch have considerably eased the implementation of complex machine learning tasks.

When leveraging machine learning libraries, developers gain access to optimized algorithms that undergo continuous updates and improvements by a community of contributors. This communal effort enhances performance, enabling developers to focus more on conceptualizing machine learning solutions rather than the intricacies of individual algorithm design.
