Volumetric quantification can be performed for various parameters of an object represented in volumetric data. Multiple views of the object can be generated, and those views provided to a set of neural networks that can generate inferences in parallel. The inferences from the different networks can be used to generate pseudo-labels for the data, for comparison purposes, which enables a co-training loss to be determined for the unlabeled data. The co-training loss can then be used to update the relevant network parameters for the overall data analysis network. If supervised data is also available then the network parameters can further be updated using the supervised loss.

A method includes sampling multiple locations within a geographic region, executing a detection process for each location, the detection process including applying the set of images for the location as input to a machine learning (ML) model that is trained to identify electrical grid assets depicted within images taken from a combination of different perspectives and obtaining an output from the machine learning model that indicates whether a same electrical grid asset is identified in each of the images of the location. In response to an ML output that indicates a positive identification of the same electrical grid asset being depicted in a particular set of images of a particular location, the method further includes: selecting a number of sublocations within the region, and executing the detection process for each sublocation.

The problem of domain shift error in computer vision models and other perception components is addressed. In a label approximation phase, an approximate label distribution is computed for each input of a target batch using a trained machine learning (ML) perception component. In an online label optimization phase, a modified label distribution is assigned to each input of the target batch, via optimization of an unsupervised loss function that (i) penalizes divergence between the approximate label distribution and the modified label distribution for each input of the target batch (ii) penalizes deviation between the modified label distributions assigned to input pairs of the target batch having similar features.
