Energy reconstruction is a crucial step for all calorimeters, which takes the digitized signal as input, and outputs the energy of the sample of interest. This paper introduces different energy reconstruction algorithms used in the CMS hadron calorimeter during LHC Run 1 and Run 2, and compares their performance. A machine learning based algorithm is also presented, which shows improved performance.
