An initial prototype called aipk was proposed by Wee Hyong Tok and implemented by Fang Zhou and Graham Williams. Graham rewrote mlhub from scratch as purely open source and based on code and concepts from wajig. Microsoft has contributed updates to mlhub through Simon Zhou who has also contributed a number of mlhub packages. The following have also assisted with model package testing and documentation reviews. Thanks to all who have helped. Karthik Bharadwaj, Tony Nolan.
