Abstract :
Motif discovery has emerged as one of the most useful techniques in processing time-series data.
One of the implementations of motif discovery is in case study 1:1 mean motion resonance (MMR)
in the astronomy field. This study aims to build a computational model and its implementation to
process time-series data and predict 1:1 MMR from asteroid orbital elements in time-series form. This
model proposes Symbolic Aggregate approximation (SAX) and Random Projection (RP) algorithms
implemented in the Python programming language. Some experiments involving ten asteroids' orbital
elements data have been carried out to validate the program. From the results obtained, we conclude
that our computational model can predict the location of the motif and with which planet the motif
is found for 1:1 resonance to occur.
