The history of AI (Artificial Intelligence) dates back to the ‘ Dartmouth Conference ’ held in1965 when the first AI fad started. After the second fad in the 1980s and the AI winter in the 1990s 2000s, the third fad is in progress. On the back of big data acquired with the Internet, practical techniques are applied in every industry. However, the structures and mechanics are hard for many students to approach. In the present report, the broad outlines of AI including deep learning, and CNN
(convolutional neural network) are explained and the specific methodology for the model construction is expounded.
