  • Publication number: 20220122001
    Abstract: Approaches presented herein provide for the generation of synthetic data to fortify a dataset for use in training a network via imitation learning. In at least one embodiment, a system is evaluated to identify failure cases, such as may correspond to false positives and false negative detections. Additional synthetic data imitating these failure cases can then be generated and utilized to provide a more abundant dataset. A network or model can then be trained, or retrained, with the original training data and the additional synthetic data. In one or more embodiments, these steps may be repeated until the evaluation metric converges, with additional synthetic training data being generated corresponding to the failure cases at each training pass.

  • Patent number: 11308338
    Abstract: In various examples, a deep neural network (DNN) is trained to accurately predict, in deployment, distances to objects and obstacles using image data alone. The DNN may be trained with ground truth data that is generated and encoded using sensor data from any number of depth predicting sensors, such as, without limitation, RADAR sensors, LIDAR sensors, and/or SONAR sensors. Camera adaptation algorithms may be used in various embodiments to adapt the DNN for use with image data generated by cameras with varying parameters—such as varying fields of view. In some examples, a post-processing safety bounds operation may be executed on the predictions of the DNN to ensure that the predictions fall within a safety-permissible range.
