摘要： A method of hybrid data labeling for machine learning, including receiving multiple unlabeled objects forming an unlabeled data set, pre-labeling the unlabeled data set by a machine learning system to output a pending label data pool, bifurcating the pending label data pool by the machine learning system into high and low confidence sets, dispatching the high confidence set to a machine labeler, dispatching the low confidence set to a human labeler, merging the label sets to return a pre-review label data pool, determining a difference between the pending label data pool and the pre-review label data pool, review labeling the data objects, if the determined difference of the data objects is greater than a predefined error threshold and storing the data objects to a reviewed pool if the determined difference of the data objects is less than and equal to the predefined error threshold.

摘要： An example method of path planning, comprising at least one of, determining an initial position and at least one vehicle constraint, predetermining a distance to a new position, determining a minimum turn radius based on the at least one vehicle constraint, selecting a vehicle turn radius that is at least as large as the minimum turn radius, determining a candidate position based on the at least one vehicle constraint and the vehicle turn radius, verifying whether the candidate position is valid with respect to the new position and converting the new position to the candidate position.
