Do you know what it means to truly learn something? You probably do, but it’s probably hard to describe that aha feeling. Precisely how we learn is not fully understood. We explore this question and also examine the difference between implicit learning and explicit learning. Implicit learning happens intuitively, almost unconsciously. Explicit learning is that which can be codified, and transmitted through a curriculum. Most education and educational reform today focuses on explicit learning — books, instructions, formulas, and tests. But true mastery is implicit. We will explore these concepts, and then ask the question about machine learning. Today, supervised machine learning is based on labeled datasets. This is explicit training of the machine. We will explore whether machine learning can be used for implicit learning.
