1. A method for determining a discharge event of a firearm, the method comprising:
receiving, by an event detection module, (i) acceleration input signals including a first acceleration input signal along a first axis, a second acceleration input signal along a second axis and a third acceleration input signal along a third axis; and (ii) rotation input signals including a first rotation input signal around the first axis, a second rotation input signal around the second axis and a third rotation input signal around the third axis;
calculating an acceleration vector magnitude from the acceleration signals;
comparing the acceleration vector magnitude to a threshold acceleration;
assigning a sample event candidate to the acceleration vector magnitude based on the comparing, the sample event candidate comprising the acceleration input signals and the rotation input signals for a predetermined duration of time;
receiving, at a machine learning module, the sample event candidate; and
determining an occurrence of a shot based on the acceleration and rotation input signals in the sample event candidate.
