  • Publication number: 20250217938
    Abstract: Weighting functions and adaptive noise distributions are provided for training a machine-learned model (e.g., image generation model) based on noised image data. A training image can be noised according to a noise distribution, which can be an adaptive noise distribution. A machine-learned model can process the noised training image to generate an output. A training system can update the machine-learned model based on a weighted loss, which can be based on the output and a weighting function. The weighting function can be monotonically non-increasing with respect to a signal-to-noise ratio. In some instances, the weighting function can have an approximately sigmoidal shape.

  • Publication number: 20240083046
    Abstract: According to an aspect, there is provided a comb attachment for a blade system, the comb attachment comprising a rack component and a pinion assembly. The rack component is defined by one of a comb and a housing and comprises a rack. The housing is configured to attach to the blade system, and the pinion assembly comprises a pinion component defined by the other of the comb and the housing. The pinion assembly further comprises an axle retained by the pinion component, and a pinion disposed on the axle such that the pinion is rotatable with respect to the pinion component. The rack and the pinion are arranged to cooperate such that rotation of the pinion on the axle induces relative linear movement between the comb and the housing.

  • Publication number: 20230267315
    Abstract: A computer-implemented method for use of a diffusion model having improved accuracy comprises obtaining input data, the input data comprising one or more channels; providing the input data to a machine-learned diffusion model, the machine-learned diffusion model comprising: a noising model comprising a plurality of noising stages, the noising model configured to introduce noise to receive the input data and produce intermediate data in response to receipt of the input data; and a denoising model configured to reconstruct output data from the intermediate data; and receiving, by the computing system, the output data from the machine-learned diffusion model. The diffusion model can include a learned noise schedule. Additionally and/or alternatively, input to the denoising model can include a set of Fourier features. Additionally and/or alternatively, the diffusion model can be trained based at least in part on a continuous-time loss for an evidence lower bound.
