    Abstract: A system and method for providing unsupervised domain adaption for spatio-temporal action localization that includes receiving video data associated with a source domain and a target domain that are associated with a surrounding environment of a vehicle. The system and method also include analyzing the video data associated with the source domain and the target domain and determining a key frame of the source domain and a key frame of the target domain. The system and method additionally include completing an action localization model to model a temporal context of actions occurring within the key frame of the source domain and the key frame of the target domain and completing an action adaption model to localize individuals and their actions and to classify the actions based on the video data. The system and method further include combining losses to complete spatio-temporal action localization of individuals and actions.

    Abstract: Systems and techniques for scene classification and prediction is provided herein. A first series of image frames of an environment from a moving vehicle may be captured. Traffic participants within the environment may be identified and masked based on a first convolutional neural network (CNN). Temporal classification may be performed to generate a series of image frames associated with temporal predictions based on a scene classification model based on CNNs and a long short-term memory (LSTM) network. Additionally, scene classification may occur based on global average pooling. Feature vectors may be generated based on different series of image frames and a fusion feature vector may be obtained by performing data fusion based on a first feature vector, a second feature vector, a third feature vector, etc. In this way, a behavior predictor may generate a predicted driver behavior based on the fusion feature.

    Abstract: A driver assistance system takes as input a number of different types of vehicle environment inputs including positions of objects in the vehicle's environment. The system identifies possible outcomes that may occur as a result of the positions of the objects in the environment. The possible outcomes include predicted positions for the objects involved in each outcome. The system uses the inputs to determine a likelihood of occurrence of each of the possible outcomes. The system also uses the inputs to determine a current risk value for objects as well as predicted risk values for objects for the possible outcomes. A total risk value can be determined by aggregating the current and predicted risk values of an object weighted by the likelihood of occurrence. Total risk values for objects can be used to determine how the driver assistance system responds to the inputs.
