    Challenge Details

    What is Predix?

    The Predix platform is a cloud-based Platform-as-a-Service (PaaS) for the Industrial Internet. The Predix platform provides tools, framework, guidelines, and best practices that enable you to create solutions to run industrial-scale analytics. As it connects machines, data, people, and other assets, the Predix platform uses leading technologies for distributed computing, big-data analytics, asset data management, and machine-to-machine communication. A comprehensive platform overview can be found here. If you have previously used or are familiar with other platforms-as-a-service (AWS, Google Cloud Platform, Heroku, IBM Bluemix), this should feel right at home.

    - Allow user to see a preview of the uploaded image.

    The application should be hosted on Predix and utilize Predix Blob Services to store and retrieve images. Please remember to include your Topcoder handle in the Predix app, so we can identify your application.

    Reliability Rating and Bonus

    For challenges that have a reliability bonus, the bonus depends on the reliability rating at the moment of registration for that project. A participant with no previous projects is considered to have no reliability rating, and therefore gets no bonus. Reliability bonus does not apply to Digital Run winnings. Since reliability rating is based on the past 15 projects, it can only have 15 discrete values.
