Resident activity recognition system and method thereof

A resident activity recognition method, adapted to recognize an activity of a non-target resident and an activity of a target resident in a region and performed by a resident activity recognition system, the resident activity recognition system comprising a memory device and a processor, the memory device storing a non-target resident model and a target resident model, the resident activity recognition method comprising:

• receiving a first testing data sent by a plurality of sensors by the processor and the first testing data including a preset weight set of the sensors and preset trigger statuses of the sensors at a present time;
• determining the activity of the non-target resident at the present time by the processor according to the non-target resident model and the first testing data;
• reducing a part of the present weight set to generate an updated weight set and a second testing data including the updated weight set and the present trigger statuses by the processor according to the activity of the non-target resident at the present time, the first testing data and the non-target resident model;
• and
• determining the activity of the target resident at the present time by the processor according to the target resident model and the second testing data.
