John Mosquera won the AWS DeepRacer Vodafone Championship in 2013 by leveraging his expertise in machine learning (ML), artificial intelligence (AI), and Python programming. The competition involved over 200 engineers, with multiple qualifying rounds leading to a final round where John emerged as the champion.John used reinforcement learning to train his AWS DeepRacer model, applying strategies borrowed from trading to optimize performance. During the qualifying rounds, he focused on managing volatility and ensuring consistent improvement, akin to an ETFs-type strategy. This involved carefully designing the reward function in Python to encourage steady progress while avoiding penalties.In the final round, John adopted a more aggressive, event-driven strategy, similar to a hedge fund (HF) approach. He refined the reward function and improved hyperparameters to maximize speed and efficiency, ensuring that the model could perform at its peak during the critical final race.John’s ability to adapt his strategies and fine-tune the model’s performance using ML and AI techniques was key to his success. His win not only demonstrated his technical skills but also his innovative approach to solving complex problems.
