Abstract: A system and a method for motion forecasting are provided. The system acquires input data including road map images and historical trajectory information of a set of agents and transforms the input data into a vectorized representation. The system generates a first candidate trajectory prediction for the set of agents by application of a motion prediction neural network on the vectorized representation. The system further generates a second candidate trajectory prediction for the set of agents by application of a rule-based prediction model on the acquired input data. The system trains the motion prediction neural network based on the first candidate trajectory prediction and a set of ground truth trajectories of the set of agents. The system generates ranking results for the first candidate trajectory prediction and the second candidate trajectory prediction based on a routing function network and trains the routing function network based on the ranking results.

Abstract: Systems and methods for pessimistic offline reinforcement learning are described herein. In one example, a method for performing offline reinforcement learning determines when sampled states are out of distribution, assigns high probability weights to the sampled states that are out of distribution, generates a fitted Q-function by solving an optimization problem with a minimization term and a maximization term, estimates a Q-value using the fitted Q-function by estimating the overall expected reward assuming the agent is in the present state and performs a present action, and updates the policy according to an existing reinforcement learning algorithm. The minimization term penalizes an overall expected reward when a present state is out of distribution. The maximization term cancels the minimization term when the present state is an in-distribution state.

Abstract: A non-invasive blood glucose detection device and a measurement method based on a multi-technology integration is provided according to the disclosure. The device combines a near-infrared spectroscopy non-invasive blood glucose detection technology with a non-invasive blood glucose detection technology based on optical polarimetry, thus improving the detection sensitivity and accuracy, simultaneously inhibiting the influence of human background and individual differences. The AOTF can be used to achieve tunable light splitting and the output lights have two orthogonal linearly polarized light characteristics. The hardware for implementing the two methods are combined. Thus, the device has the advantages of simple structure, strong anti-interference ability and low cost. In addition, it combines the two methods on software by adopting a random forest algorithm and a data fusion algorithm, which effectively improves the prediction accuracy of non-invasive blood glucose concentration.
