  • Publication number: 20230281643
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating models. In some implementations, a system obtains data that comprises promotions and parameters for an opportunity. The system generates transformation spaces based on the promotions and the parameters, wherein each transformation space comprises states, each state is based on the parameters for a particular promotion. The system iterates over a number of iterations. For each transformation space, the system adjusts a state of the transformation space based on actions. The system generates a model by combining each adjusted state. The system generates an entropy for the model. The system compares the entropy to a threshold value, wherein the threshold value corresponds to one of the parameters. In response to determining that the entropy exceeds the threshold value, the system iterates. The system provides the generated model for output.

  • Publication number: 20230194684
    Abstract: Systems and methods for detecting blockages for light detection and ranging (“LiDAR”) devices are disclosed. According to one embodiment, a light detection and ranging (LiDAR) blockage detection method includes emitting, by an active channel of a plurality of channels of a LiDAR device, an optical signal toward a configured position on a housing of the LiDAR device. A passive listening channel of the plurality of channels receives a return signal originating from the optical signal. Based on a comparison of data derived from the return signal and data derive from a reference signal, a determination is made as to whether a blockage is present at the configured position on the housing.
