How a 25‑Year‑Old Java Engineer Can Transition into AI: Learning Path & Resources

In the "Ask the Expert" column, many readers wrote in with career‑development questions; this piece addresses a 25‑year‑old Java developer who wants to switch to artificial intelligence.

The surge of deep learning is traced back to milestones such as AlphaGo’s 2016 victory over Lee Sedol and AlexNet’s breakthrough in the 2012 ImageNet competition, which demonstrated the power of deep neural networks.

Basic Concepts

Machine Learning vs. Deep Learning

Deep learning is a subset of machine learning; machine learning also includes techniques like support vector machines, decision trees, and random forests, as well as theoretical principles such as Occam’s razor.

Deep learning focuses on deep neural networks with many layers and complex architectures, achieving superior results when massive training data are available.

Machine Learning and Big Data

Big data provides the foundation for machine learning, though it often emphasizes statistical learning methods.

Relationships among machine learning, deep learning, data mining, and big data are illustrated in the diagram below.

Recommended Learning Materials

After deep learning became popular, many resources appeared online, but their quality varies. The author, who has followed deep learning since 2013, recommends high‑quality materials that convey the essence of the field.
