Maquette The Paytm platform for fraud prevention
From Wikipedia:
A Markov chain (discrete-time Markov chain or DTMC[1]), named after Andrey Markov, is a random process that undergoes transitions from one state to another on a state space.
Coincidentally,
A maquette (French word for scale model, sometimes referred to by the Italian names plastico or modello) is a small scale model or rough draft of an unfinished sculpture.
