Abstract

An electronic device and a method for implementation for deep-learning based peak detection in biological signal. The electronic device receives a biological signal associated with a user. The electronic device detects a first peak and a first trough associated with the first peak, from the received biological signal. The electronic device applies a local search algorithm on the received biological signal. The electronic device refines the detected first peak and the first trough based on the application of the local search algorithm on the received biological signal. The electronic device determines a health condition associated with the user based on the refined first peak and the first trough.
