Numerai is a San Francisco-based hedge fund that uses machine learning to make trades in financial markets. It utilizes a global network of data scientists who compete to create the best trading algorithms, with their algorithms being evaluated based on how well they perform on new, unseen data. The platform is built on the Ethereum blockchain and uses the NMR token as its native currency to incentivize data scientists to submit high-quality and accurate algorithms. This creates a more secure and decentralized approach to hedge fund management and can potentially lead to more profitable trades
