Machine learning for home understanding and notification

A method comprising:

• obtaining, by one or more processors, reference videos from a camera within a home;
• determining, by the one or more processors and from the reference videos, that a particular person routinely leaves the home with a particular object at a particular time of day;
• determining, by the one or more processors and from a sample video from the camera within the home, that the particular person appears to be leaving the home without the particular object at the particular time of day;
• and
• in response to determining from the sample video from the camera within the home that the particular person appears to be leaving the home without the particular object at the particular time of day, providing a notification regarding the particular object.

A computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

• obtaining reference videos from a camera within a home;
• determining from the reference videos that a particular person routinely leaves the home with a particular object at a particular time of day;
• determining from a sample video from the camera within the home that the particular person appears to be leaving the home without the particular object at the particular time of day;
• and
• in response to determining from the sample video from the camera within the home that the particular person appears to be leaving the home without the particular object at the particular time of day, providing a notification regarding the particular object.
