Frequently Asked Questions

How will my submission be scored?

There are two parts to the competition - processing the images to find features, and then estimating the overall grade (high, medium, low or waste) of the image.

While the competition is open you only need to submit the estimated grade and percentages. We’ll score your submission based on the number of correct answers. We’ll let you know your score, and update a leaderboard of the current highest-ranked submissions.

At the end of the competition we’ll ask the top 5 ranked submissions to submit their algorithm for full assessment. We’ll look at the accuracy of the results, but also look at subjective criteria such as the classified images, code quality, ease of integration, etc. We’ll then award the 1st, 2nd and 3rd prizes.

Who owns the Intellectual Property in my submission?

You always retain full ownership of your IP.

While the competition is open you do not need to submit any source code for your algorithm, only the results.

When submissions close if you are ranked in the top 5 we will invite you to submit your algorithm. You’ll need to grant us a 30 day non-exclusive license to the algorithm solely for us to assess it.

If you are selected as the winner, in return for the $10,000 prize you must assign a perpetual non-exclusive royalty-free license to Gold Fields, for Gold Fields’ internal use only. You will continue to own your algorithm, and are free to do whatever you like with it, including selling it to others.

Can I submit multiple times?

Yes, you can submit early and then refine your algorithm and submit again later. Your algorithm will be ranked based on its best score.

If two or more people have submissions with the same score, then they will be ranked based on the date they were submitted. So we encourage you to submit early.
