This document discusses using neural networks for geofencing applications. It presents three main existing methods for calculating geofences (ray casting, winding number, and triangle weight characterization) and notes that complex shapes increase the time and space complexity of these algorithms. The document then outlines a system architecture using a client-server model with neural networks to optimize geofence detection times. It describes setting up a server application to generate training data from geofence shapes and train models, which are then downloaded to an Android application for low-latency geofence detection using input coordinates.
