Rist’s Remarkable Achievement in the Geophysical Waveform Inversion Competition
In a stunning display of expertise, the Rist Kaggle Team has clinched a gold medal at the renowned
Kaggle competition titled
Yale/UNC-CH - Geophysical Waveform Inversion. The competition, organized by Yale University, took place from April 8 to June 30, 2025, challenging participants to estimate subsurface characteristics such as velocity maps using seismic waveform data.
The
team member,
Chen Jian, a Kaggle Grandmaster, achieved an impressive ranking of third among
1,749 participants and
1,388 teams competing on this global stage. Chen's expertise not only secured a medal for Rist but also highlighted the ongoing promise and potential within the organization’s data analytics capabilities.
Here’s how the competition placed:
- - 1st Place: Team A
- - 2nd Place: Team B
- - 3rd Place: Chen's Team from Rist

Challenges Faced by Chen
Chen shared that the competition posed unique challenges, chiefly due to an extensive dataset and limitless data generation capabilities. This necessitated substantial engineering efforts. Key strategies that Chen focused on included:
1.
Enhancing Data Generation Speed: Speed was crucial; optimizing forward modeling and transitioning to GPU acceleration were essential steps. Moreover, devising effective strategies for creating synthetic training samples was vital.
2.
Accelerating Training Speed: This involved making informed architectural choices and developing efficient data processing pipelines. Moreover, resource management became a priority considering the limited GPU hours available. Chen had to make strategic choices around model selection and meticulously plan training processes to maximize performance within these constraints.
3.
Implementation Details: Given that training can consume significant GPU hours, ensuring consistency and reproducibility became critical.
Through these experiences, Chen recognized that tackling machine learning problems demands not just innovative algorithms but also exceptional engineering practices and resource optimization.
What is Kaggle?
For those unfamiliar,
Kaggle is a prominent data analysis platform boasting over
24 million registered users. It functions by hosting competitions where data challenges posed by companies and organizations invite participants, known as
Kagglers, to contend for accuracy in their analytical models. Participants are ranked based on their performance and can achieve titles from
Kaggle Novice to
Kaggle Grandmaster, the latter title held by an elite group of just
372 individuals globally.
