Rist's Kaggle Team Achieves Gold Medal in Geophysical Waveform Competition

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

More detailed competition outcomes can be viewed on the Kaggle leaderboard, while discussions can be explored further in the Kaggle forums.

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.

Rist: The Home of Elite Data Scientists


Founded in 2016, Rist has made significant strides in the tech arena, especially since it launched the Kaggle recruitment program in 2020 to incorporate top-performing Kagglers. The Rist Kaggle Team now boasts 10 Grandmasters and 2 Masters, all dedicated to providing high-level data analysis and AI technology solutions.

Rist is not only at the forefront of data analytics but actively supports industry DX (Digital Transformation) efforts and research development initiatives. They work on diverse technological solutions tailored to meet various organizational needs.
