Usage Notes
机器学习 is a direct calque of the English term "machine learning." It is closely related to 人工智能 (artificial intelligence) and 深度学习 (deep learning) -- with 机器学习 being the broader category and 深度学习 being a specific subtype using neural networks.
In Chinese tech media and academic papers, 机器学习 appears frequently alongside 数据科学 (data science), 算法 (algorithm), and 神经网络 (neural network). B2 learners in STEM or technology fields should treat this as a fixed compound.
Memory Hook
机器 = machine. 学习 = learning/to study. Machine learning is exactly what it says -- machines that learn. Picture a robot sitting at a school desk, studying endless data to get smarter.
