Nvidia patents neural networks that work on 3D shapes of any size
Nvidia describes a method for building artificial intelligence models that process 3D objects made of triangles, known as meshes. The system creates specific mathematical tools, or operators, that allow the AI to analyze these shapes effectively. These tools can be reused for different 3D objects, even if their structures are not identical.
In the filing’s own words
Convolutional operators for triangle meshes are determined to construct one or more neural networks. In at least one embodiment, convolutional operators, pooling operators, and unpooling operators are determined to construct the one or more neural networks, in which the same learned weights from the one or more neural networks can further be used for triangle meshes with different topologies.
What exactly they claim (claim 1)
1. A system, comprising: one or more computers having one or more processors to train a neural network by: performing a convolution on data input, at a layer of the neural network, wherein the convolution is performed by using convolutional operators on the data input, the convolutional operators having been determined by: selecting a vertex from a plurality of vertices of the data input; obtaining a plurality of sampling points positioned uniformly around the selected vertex based on a length of the convolutional operators, at least a portion of the plurality of sampling points being other than one of the plurality of vertices; adding at least a portion of the plurality of vertices to a list such that each vertex in the portion of the plurality of vertices is or is paired with a sampled point from the plurality of sampling points; and determining, based at least in part of the list, a set of vertices to form the convolutional operators; and using the convolutional operators on the data input to generate a set of outputs of the convolution.
