I want to transfer PointNext or some other model to a different problem, where the task is to classify (or rather detect) a number of specific points in a point cloud. So to say somewhat of a keypoint detection in a point cloud. The dataset is rather small and it might not be as easy to generate new training samples.
I have a couple of questions:
What approach do you feel would be most likely to achieve that goal?
a. Transfer learning from the pretrained model for (I guess?) ShapeNetPartSeg?
b. Train a model from scratch?
c. Use a different algorithm family than the point cloud algorithms proposed here (because there might be better algorithms to solve such a problem?)
Can I model that problem in your openpoints framework? What I mean is can I create a yaml which will represent that kind of training (as decided in question 1)?
And how much benefit can I expect from generating more training samples?
To my understanding right now the ShapeNet input data contains of a 7dimensional vector. 3 position, 3 normal and 1...?. Part label? And could this be adapted to be only position and label?
Hey there, I really love the project, thanks!
