Suppose you are a quality engineer at a shop-floor. You have been given a task of making a system that recommends quality of components based on activities of a machining process. You realize that materials being used, and machine-tools parameters could be highly variable. Hence, you would decide to:I. First, cluster machine parameters into operating modes andII. Second, train separate models for each operating mode to predict quality of products.The first task is a/an ____ learning problem while the second is a/an ____ learning problem. Choose from the options:

A	Supervised and unsupervised
B	Unsupervised and supervised
C	Supervised and supervised
D	Unsupervised and unsupervised

Explanation:

Detailed explanation-1: -Speed and position are controlled by using a sliding table and a spindle. The punch tape reader in a CNC machine is an input device. Magnetic tape, as well as computer keyboard, can be used in CNC as an input device.

Detailed explanation-2: -Closed-loop Systems Summary Closed-loop control systems are also called “feedback control systems” are very common in process control and electronic control systems. Feedback systems have part of their output signal “fed back” to the input for comparison with the desired set point condition.

Detailed explanation-3: -On such programmable machines, punch tapes were used to feed the program data required for its operation. These machines were called numerical control machines (NC machines).

Detailed explanation-4: -The elements of control unit include of tape reader, a data buffer, signal input channel to the machine tool and the feedback channel from the machine tool. It also consists the sequence control to coordinate the whole operation of preceding element.
