Harder B-spline Dataset

Harder B-spline Dataset From article Point Relative Knot Matrix for B-spline Curve Approximation with Transformer Neural Networks. This dataset contains Cubic B-spline curves with randomly generated knots and control points. The set contains 120,000 different curves, each curve having between 9 and 28 knots, equally represented (6,000 per category). Curves are not sampled. This dataset was originally generated to train a Deep Neural Network on B-spline curve approximation. The dataset is divided in two subset : train and val of respectively 114,000 and 6,000 curves sampled from the full dataset. You are free to use other subdivision of the dataset. More technical information about the data can be found in the Readme file. Feel free to contact the author if you have any questions/problems regarding the data.
