  • Publication number: 20240249125
    Abstract: A method for a task-agnostic policy filter control system is described. The method includes encoding a current observation, a previous latent state, and a previous action to output a new latent state. The method also includes computing, by a neural ordinary differential equations (ODE) module, learned latent state-space dynamic models for the new latent state. The method further includes inferring, by an in-distribution barrier function (iDBF) model, an iDBF value in response to the new latent state. The method also includes computing, based on the learned latent state-space dynamic models, the iDBF value and a reference control input for a current timestep, and a current action. The current action keeps the task-agnostic policy filter control system in-distribution with respect to an offline-collected dataset of safe demonstrations.

  • Publication number: 20240182078
    Abstract: A method of forecasting risk-biased trajectories of agents surrounding an ego vehicle is described. The method includes sampling a risk-neutral latent space generated by a trained encoder of a generative network based on past surrounding agent trajectories. The method also includes predicting, based on the sampling of the risk-neutral latent space, risk-neutral future surrounding agent trajectories using a trained decoder of the generative network. The method further includes sampling a risk-biased latent space distribution generated by a trained, risk-aware encoder of the generative network based on past trajectories of the ego vehicle and a risk-sensitivity. The method also includes predicting, based on the sampling of the risk-biased latent space distribution, risk-biased future surrounding agent trajectories using the trained decoder of the generative network.

  • Publication number: 20240129686
    Abstract: A display control apparatus for controlling display of a display device that a user can wear acquires speech collected by a plurality of microphones, estimates a sound-arrival direction of the acquired speech, and generates a text image corresponding to the acquired speech. The display control apparatus determines an adjustment amount of a display position of the text image on the display unit of the display device based on a detection result of at least one of an operation by the user and a state of the display device. Then, the display control apparatus displays the generated text image at a display position in the display unit, the display position being determined in accordance with the estimated sound-arrival direction and the determined adjustment amount.
