Latest Patents

One of his latest patents is titled "Generating human motion sequences utilizing unsupervised learning of discretized features via a neural network encoder-decoder." This invention discloses methods, systems, and non-transitory computer-readable storage media for utilizing unsupervised learning of discrete human motions to generate digital human motion sequences. The system employs an encoder of a discretized motion model to extract a sequence of latent feature representations from a human motion sequence in an unlabeled digital scene. It also determines sampling probabilities from these representations in connection with a codebook of discretized feature representations associated with human motions. The system converts the sequence of latent feature representations into a sequence of discretized feature representations by sampling from the codebook based on the sampling probabilities. Additionally, it utilizes a decoder to reconstruct a human motion sequence from the discretized feature representations, employing a reconstruction loss and a distribution loss to learn parameters of the discretized motion model.

Another notable patent is "Contact-aware retargeting of motion." This method involves a processing device that receives a request to retarget a source motion into a target object. The operations include providing the target object to a contact-aware motion retargeting neural network trained to retarget the source motion into the target object. The network generates retargeted motion for the target object based on a self-contact having a pair of input vertices. The retargeted motion is subject to motion constraints that preserve the relative location of the self-contact and prevent self-penetration of the target object.
