This project is more on the academic side -- disclaimer, I was involved in it, but it's led by Justin Harris at Microsoft Research: "Sharing Updatable Models on Blockchain" https://github.com/microsoft/0xDeCA10B
The idea is that the smart contract is a learning algorithm, and people can donate data to a public repository stored on a blockchain. The learned model is publicly available for everyone. People can also receive incentives for donating data in some implementations.
