Learning to smell challenge Community Contribution Prize

Seismic Facies Identification challenge Community Contribution Prize


AI Blitz⚡#4 is open to everyone who is interested in diving into the world of Data sciences - students, professionals or researchers. With problems of varying difficulty, we try to ensure that there is something to learn for everyone.

🎁 challenge bundling

We are bundling Learning to smell and Seismic Facies identification challenges as a part of AI Blitz⚡#4 and we are very excited to see how the AI Blitz⚡ community tackles them!

For participation, by agreeing to the AI Blitz rules you also agree to both the challenges’ rules and in case of any discrepancies, the individual challenge’s rules supersede AI Blitz⚡ rules.

What this means for the leaderboard

If you participate in AI Blitz, you also become a participant of the original challenges (learning to smell and seismic facies). You can access the AI Blitz specific leaderboard to see how you are competing with AI Blitz participants and you can also access the main challenge leaderboard that will have ALL the participants of that challenge beyond Blitz.

What if you are already a participant in either of Learning to Smell or Seismic Facies

Nothing changes for you. If you would like to try your hand at AI Blitz and solve other puzzles in Blitz, you can easily participate.

What this means for prizes

If you are an AI Blitz participant, based on your leaderboard rank, you are eligible for the AI Blitz $500 prize pool. Top rank on Blitz leaderboard does not necessarily mean top rank on main Learning to smell or Seismic Facies leaderboards(seperate from Blitz). These challenges have individual prizes and although you are eligible for those by participating in AI Blitz, you win them only when you are on top of their respective leaderboards.

Winning rules for Blitz

Blitz winning rules also mandate that you open source all your 5 solutions from the challenge, which includes your solutions for Learning to smell and Seismic Facies. Failing which, you may be ineligible for the cash prize.
