Researcher

Germain Kolossov

Germain Kolossov is a machine learning researcher whose work studies training-data selection and diffusion-based generation. In 2023, he coauthored a paper with Andrea Montanari and Pulkit Tandon on data selection under weak supervision. The work was presented orally at ICLR and received an Honorable Mention in 2024; their experiments found cases where training on 40% of a dataset had a lower error rate than training on the full dataset. In 2026, he coauthored research on generating random solutions to k-SAT and k-XORSAT formulas. By September 2026, he is a researcher affiliated with Granica Computing Inc.

Timeline

  1. 2023

    A theory of data selection

    In 2023, he coauthors “Towards a statistical theory of data selection under weak supervision” with Andrea Montanari and Pulkit Tandon. The paper selects a smaller sample, acquires its labels, and uses them to train a model.

  2. 2024

    An oral ICLR presentation

    In 2024, his data-selection paper is presented orally at ICLR.

  3. 2024

    Training on less data

    In 2024, he and his coauthors test their selection method on a real autonomous-vehicle dataset; in some cases, training on 40% of the original data yields a lower error rate than training on the full set.

  4. 2024

    An ICLR honorable mention

    ICLR gives an Honorable Mention in 2024 to the data-selection paper he coauthors with Andrea Montanari and Pulkit Tandon.

  5. 2026

    Diffusion for discrete generation

    In 2026, he coauthors “Generating from Discrete Distributions Using Diffusions: Insights from Random Constraint Satisfaction Problems.” The paper studies generating uniformly random solutions to random k-SAT and k-XORSAT formulas.

  6. By September 2026

    Research at Granica

    By September 2026, he is a researcher affiliated with Granica Computing Inc.
