1. An electronic device comprising:
one or more processing circuits;
memory; and
one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processing circuits, the one or more programs including instructions for:
segmenting a signal representative of respiration into segments that are equal in length using a sliding window such that the segments overlap;
computing frequency domain representations of the segments;
generating an input image from the frequency domain representations of the segments; and
classifying the segments to identify one or more apnea/hypopnea events, wherein classifying the segments to identify the one or more apnea/hypopnea events comprises applying a machine learning model to the input image to identify the one or more apnea/hypopnea events in the segments.
