One embodiment provides an apparatus. The apparatus includes a companion device. The companion device includes pattern recognition logic to construct a reference graph model based, at least in part, on a plurality of events captured from at least one of the companion device and a wearable device. The reference graph model includes at least one path, each path including one trigger node, at least one event node and a respective edge incident to each event node, a first edge coupling the trigger node and a first event node, a weight associated with each edge corresponding to a likelihood that a second event will follow a first event within a minimum trigger time interval.
