Latest Patents

Cheng's latest patents include innovative systems and methods for processing sparse tensors using trained neural network models. One of his notable inventions focuses on the processing of sparse input point clouds through an encoder stage that utilizes a series of encoder blocks. Each block is equipped with a sparse convolution layer, a sparse intra-channel attention module, a sparse inter-channel attention module, and a sparse residual tower module. The output from this encoder stage is further processed in a decoder stage, which also comprises several decoder blocks, ultimately resulting in an output sparse tensor that represents a labeled output point cloud.

Another significant patent involves a computer-implemented method for semantic segmentation of point cloud frames. This method allows for the reception of point cloud frames, including a target frame, and applies semantic labels to points within these frames. By determining the most prevalent semantic label for each point across a sliding set of sequences, Cheng's invention enhances the accuracy and efficiency of point cloud analysis.
