Abstract

Disclosed herein is a washing machine including a first data acquirer configured to collect data related to a laundry pattern of a user, a second data acquirer configured to collect data related to context information, and a processor configured to provide the laundry pattern of the user and the context information to a reinforcement learning model as an environment and to train the reinforcement learning model using feedback of the user on a recommended laundry course when the reinforcement learning model recommends the laundry course.

Claims (24)

1. A washing machine, comprising:

one or more sensors;

one or more processors configured to:

obtain a laundry pattern of a user;

obtain context information via the one or more sensors, wherein the obtained context information is related to a particular operation event of the washing machine by the user;

provide the obtained laundry pattern and the obtained context information to a reinforcement learning model associated with the user; and

obtain a recommended operation setting of the washing machine for the particular operation event provided by the reinforcement learning model based on the laundry pattern and the context information;

determine feedback of the user for the recommended operation setting; and

provide the determined feedback to the reinforcement learning model to further train the model associated with the user; and

a wireless communication unit,

wherein:

the context information comprises at least personal information of the user received via the wireless communication unit which includes a scheduled event of the user prior to a time of the particular operation event; and

the recommended operation setting is selected to effectively clean clothing items worn by the user during the scheduled event.

2. The washing machine of claim 1 , wherein the context information further comprises a plurality of data points and one or more of the plurality of data points is obtained via the wireless communication unit.

3. The washing machine of claim 1 , wherein the context information further comprises at least a type of laundry item for the particular operation event, information on an environment of the washing machine, information on a laundry detergent for the particular operation event, or a laundry pattern of a similar user.

4. The washing machine of claim 3 , wherein the personal information of the user further includes at least information on a health of the user, schedule information of the user, e-mail history of the user, or a purchase history of the user.

5. The washing machine of claim 3 , wherein the information on the environment of the washing machine comprises a least information on a date, time, day of the week, season, temperature, or humidity associated with the particular operation event of the washing machine.

6. The washing machine of claim 1 , further comprising a memory, wherein the obtained laundry pattern of the user is based on information, stored in the memory, of a plurality of previous operations of the washing machine associated with the user.

7. The washing machine of claim 6 , further comprising a microphone, wherein the one or more processors are further configured to:

receive a voice input from the user via the microphone for setting the washing machine for the particular operation event;

identify the user based on voice recognition of the received voice input; and

obtain the laundry pattern from the memory based on the identification of the user based on voice recognition.

8. The washing machine of claim 1 , wherein the feedback of the user comprises one of a positive reinforcement resulting from the user selecting the recommended operation setting for the particular operation event or a negative reinforcement resulting from the user selecting another operation setting for the particular operation event.

9. The washing machine of claim 8 , wherein the one or more processors are further configured to update stored preferences of the user based on a difference between the recommended laundry course and selected another operation setting.
