Training system and training method for human-presence detection model

A training system for a human-presence detection model comprising:

• a distance sensor;
• a temperature sensor;
• and
• a host device electrically connected to the distance sensor and the temperature sensor;
• wherein the host device obtains a plurality of training samples by the distance sensor and the temperature sensor, each of the training samples includes distance data and temperature data, the host device divides the plurality of training samples into a first data cluster and a second data cluster according to whether or not an input interface of the host device is in a used state, and the first data cluster corresponds to the used state;
• wherein the host device marks the first data cluster as a human-presence cluster;
• wherein the host device selects a sub-cluster from the second data cluster, a center point of the sub-cluster corresponds to a maximum distance value and a minimum temperature value, and the host device marks the sub-cluster as a human-absence cluster;
• wherein the host device performs machine learning for the human-presence cluster and the human-absence cluster to generate the human-presence detection model.
