Artificial intelligence washing machine and method of controlling the same

A method of controlling a washing machine, the method comprising:

• accelerating a washing tub having laundry introduced thereinto;
• obtaining an electrical current value that is supplied to a motor configured to rotate the washing tub in a period in which the washing tub is rotated while being accelerated;
• obtaining a state of the laundry that is received in the washing tub, from an output of an output layer of a pre-trained machine-learning based on an input to an input layer of the machine-learning network that comprises the electrical current value;
• and
• performing a washing cycle operation that comprises washing the laundry according to a washing mode that is determined based on the state of the laundry.

A washing machine comprising:

• a washing tub configured to receive laundry, the washing tub being configured to be rotatable;
• a motor configured to rotate the washing tub;
• a controller configured to control the motor such that the washing tub is rotated while being accelerated;
• and
• a current sensing unit configured to sense an electrical current value of the motor,
• wherein the controller is configured to:
• determine a state of laundry received in the washing tub, from an output of an output layer of a pre-trained machine-learning network based on an input to an input layer of the machine-learning network that comprises an electrical current value supplied to the motor during accelerated rotation of the washing tub;
• selecting, based on the state of the laundry, one of a plurality of washing modes that are classified in consideration of (i) a wear degree of the laundry or (ii) a washing strength of the laundry;
• and
• performing a washing cycle operation that comprises washing the laundry according to the selected washing mode.
