摘要： A method for performing a task by a robotic device includes mapping a group of task image pixel descriptors associated with a first group of pixels in a task image of a task environment to a group of teaching image pixel descriptors associated with a second group of pixels in a teaching image based on positioning the robotic device within the task environment. The method also includes determining a relative transform between the task image and the teaching image based on mapping the plurality of task image pixel descriptors. The relative transform indicates a change in one or more of points of 3D space between the task image and the teaching image. The method also includes performing the task associated with the set of parameterized behaviors based on updating one or more parameters of a set of parameterized behaviors associated with the teaching image based on determining the relative transform.

摘要： A system and method are provided for making a probabilistic determination of the state of a lane transition which may be controlled by a traffic signal, such as a traffic cue. A determination of the state of transition of a traffic signal may be used by a vehicle to determine a course of action to take. In making the determination, the states of multiple traffic signals may be combined into one collection of elements that has values associated with the likelihood of the traffic signals being in a given state. Optionally, a determination may be made of whether a traffic signal is occluded.

摘要： A method for fusing neural radiance fields (NeRFs) is described. The method includes re-rendering a first NeRF and a second NeRF at different viewpoints to form synthesized images from the first NeRF and the second NeRF. The method also includes inferring a transformation between a re-rendered first NeRF and a re-rendered second NeRF based on the synthesized images from the first NeRF and the second NeRF. The method further includes blending the re-rendered first NeRF and the re-rendered second NeRF based on the inferred transformation to fuse the first NeRF and the second NeRF.

摘要： Systems, methods, and other embodiments described herein relate to estimating scaled depth maps by sampling variational representations of an image using a learning model. In one embodiment, a method includes encoding data embeddings by a learning model to form conditioned latent representations using attention networks, the data embeddings including features about an image from a camera and calibration information about the camera. The method also includes computing a probability distribution of the conditioned latent representations by factoring scale priors. The method also includes sampling the probability distribution to generate variations for the data embeddings. The method also includes estimating scaled depth maps of a scene from the variations at different coordinates using the attention networks.

摘要： A method for processing text prompts includes identifying a set of elements in a text prompt that form a basis for a generative output. The method also includes identifying an element of the set of elements that satisfy a refinement condition. The method further includes updating the element based on the element satisfying the refinement condition. The method still further includes generating the generative output in accordance with updating the element.

摘要： A method includes inputting a source into a weighted and undirected graph having a plurality of nodes and edges, inputting a target, inputting a plurality of objectives, searching the graph using a rapidly exploring random tree algorithm to determine a solution path that meets an existence constraint and an order constraint, determining a plurality of paths between the source and the target that intersects with each one of the plurality of objectives at least once that conforms with the existence constraint, assigning a travel cost for each of the determined plurality of paths, determining a visiting order of the plurality of objectives that reduces the assigned travel cost by the RRT* algorithm asymptotically decreasing with an allocated computation time by rewiring each one of the plurality of objectives and outputting the solution path to form a connected graph having the plurality of nodes.

摘要： System, methods, and other embodiments described herein relate to tire models based on neural-Exp Tanh parameterization. In one embodiment, a method includes operating a vehicle with a control framework incorporating an Exp Tanh function; calculating prior slip data based on measurements obtained by the control framework; selecting a confidence parameter; using a first predictive model to determine Exp Tanh parameters based upon the prior slip data, the measurements, and the confidence parameter; and inputting a slip parameter and the Exp Tanh parameters into the Exp Tanh function to estimate a tire force.

摘要： A method for vehicle prediction, planning, and control is described. The method includes separately encoding traffic state information at an intersection into corresponding traffic state latent spaces. The method also includes aggregating the corresponding traffic state latent spaces to form a generalized traffic geometry latent space. The method further includes interpreting the generalized traffic geometry latent space to form a traffic flow map including current and future vehicle trajectories. The method also includes decoding the generalized traffic geometry latent space to predict a vehicle behavior according to the traffic flow map based on the current and future vehicle trajectories.

摘要： A computer implemented method for determining optimal values for operational parameters for a model predictive controller for controlling a vehicle, can receive from a data store or a graphical user interface, ranges for one or more external parameters. The computer implemented method can determine optimum values for external parameters of the vehicle by simulating a vehicle operation across the ranges of the one or more operational parameters by solving a vehicle control problem and determining an output of the vehicle control problem based on a result for the simulated vehicle operation. A vehicle can include a processing component configured to adjust a control input for an actuator of the vehicle according to a control algorithm and based on the optimum values of the vehicle parameter as determined by the computer implemented method.
