Presence detection based on link parameter data and network parameter data

Techniques for presence detection are described. In an example, system receives, from a first device connected with a computer network that is associated with a location, a first value of a first parameter associated with a link between the first device and a second device. The system determines, using a first prediction model and the first value, a first likelihood of presence at the location. The first prediction model is configured based at least in part on outputs of a second prediction model that uses a second parameter associated with the computer network. The system determines whether the presence is detected at the location based at least in part on the first likelihood.
