Starmine is a robust and highly scalable platform for constructing, trading and exchanging advanced algorithmically generated on-demand datasets for Machine Learning (ML) and Artificial Intelligence (AI) efforts. Datasets remain at the core of most advances in ML and Al. A dataset is typically made up of rows and columns, similar to an organized matrix or spreadsheet. Specifically, columns contain features along with continuously valued attributes or scores. These features and their scored attributes are stored as ‘supercolumns’ and can be automatically engineered, traded or exchanged by machines without human intervention. This can also be done with full anonymity using Starmine tokens to execute and transact smart contracts where each dataset or each individual feature column in any dataset can be treated as a tradable asset which is transacted and executed via smart contracts on the blockchain.
