  • Publication number: 20240086693
    Abstract: Methods and systems for budgeted and simplified training of deep neural networks (DNNs) are disclosed. In one example, a trainer is to train a DNN using a plurality of training sub-images derived from a down-sampled training image. A tester is to test the trained DNN using a plurality of testing sub-images derived from a down-sampled testing image. In another example, in a recurrent deep Q-network (RDQN) having a local attention mechanism located between a convolutional neural network (CNN) and a long-short time memory (LSTM), a plurality of feature maps are generated by the CNN from an input image. Hard-attention is applied by the local attention mechanism to the generated plurality of feature maps by selecting a subset of the generated feature maps. Soft attention is applied by the local attention mechanism to the selected subset of generated feature maps by providing weights to the selected subset of generated feature maps in obtaining weighted feature maps.

  • Publication number: 20240075955
    Abstract: A safety-guaranteed control system for automated vehicles (AVs) considers both vehicle and tire stabilities on varying road conditions. Conventional AV control systems may not be sufficient to adequately handle control-dependent and time-varying safety constraints. The system integrates control-dependent barrier functions (CDBF) and time-varying CBFs (TCBFs) with control Lyapunov functions (CLFs) in a quadratic programming problem.
