Abstract: Methods, systems, and media for screening users of a virtual environment are provided.

Abstract: Methods, systems, and media for determining viewability of three-dimensional digital advertisements are provided.

Abstract: Methods, systems, and media for determining curved advertisement viewability in virtual environments are provided.

Abstract: Methods, systems, and media for determining viewability of a content item in a virtual environment having particles are provided. In some embodiments, the method comprises: selecting a first plurality of pixels of the content item; determining a first plurality of color values of the first plurality of pixels of the content item; selecting a second plurality of pixels of an image of a rendered screen of a virtual environment; determining a second plurality of color values of the second plurality of pixels of the image of the rendered screen of the virtual environment; comparing the first plurality of color values with the second plurality of color values; and determining whether the content item being presented within the virtual environment is being obstructed by a visual element based on the comparison.

Abstract: Monitoring may be performed for time series prediction models. Data to generate a new time series forecast may be received. A determination may be made that the data is associated with a previously generated time series forecast by a machine learning model. Performance metrics may be generated for the machine learning model according to a comparison of the data with the previously generated time series forecast. The performance metrics can then be provided for further analysis and action.
