Innovamat is an educational organization focused on mathematics learning. Our mission is to improve the way the subject is taught, by offering resources, training and research to the educational community. When a student solves a problem on a digital board, we receive the pen strokes themselves — not a photograph, not typed text. It is a multiple-instance detection problem on handwritten input, solved directly on the pen strokes rather than on a rendered image — a formulation with no off-the-shelf solution to copy and no public benchmark that stands in for the real thing. The work is genuine research engineering: understand where the model falls short, form a hypothesis about why, build it, and find out honestly whether it worked.
Run controlled comparisons with success criteria agreed before the run, so a result means what it appears to mean.
Take a model through to something that answers fast enough on ordinary school hardware, not only on a training GPU.
Judge honestly when the limit is the model, when it is the data, and when the task itself is genuinely ambiguous.




You have built models that find a variable, unknown number of objects in a single input and attribute each part of that input to exactly one of them — including how predictions get matched to ground truth during training, and what the resulting metrics do and don't tell you.
Strokes, polylines, trajectories, point clouds, graphs, vector graphics, CAD geometry or sensor traces — anywhere the input is a set of geometric primitives rather than an image. Serious experience training deep models in PyTorch — not calling a training API, but owning the loop: schedules, numerical stability, distributed runs, and the debugging of a model that trains happily without getting better.
Online handwriting, sketch, ink or diagram recognition, in any script or notation.
Geometric deep learning, or graph neural networks applied to spatial data.
Vector graphics, CAD, GIS or trajectory modelling in an industrial setting.
