Title: SENSOR DATA LABEL VALIDATION
Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium that validates labels associated with sensor measurements of a scene in an environment. One of the methods includes receiving data representing a sensor measurement of a scene in an environment generated by one or more sensors. The sensor measurement can be associated with one or more labels, and each label can identify a portion of the sensor measurement that has been classified as measuring an object in the environment. For each of the labels, a determination can be made as to whether the label satisfies each of the validation criteria. Each validation criterion can measure whether one or more characteristics of the label are consistent with one or more characteristics of real-world objects in the environment. In response to determining that a particular label of the one or more labels does not satisfy one or more of the validation criteria, a notification can be generated indicating that the particular label is not a valid label for any real-world object in the scene of the environment.

Claims: number: 1
text: A computer-implemented method comprising:
number: 2
text: The method of claim 1, further comprising:
providing the notification to a user device for presentation to a user.
number: 3
text: The method of claim 2, further comprising:
number: 4
text: The method of claim 3, further comprising:
prior to including the updated label data in the set of validated label data, determining that the updated label satisfies all of the validation criteria.
number: 5
text: The method of claim 3 or 4, further comprising:
training a machine learning model on training data that includes the set of validated labels for the sensor measurement.
number: 6
text: The computer-implemented method of any preceding claim further comprising:
number: 7
text: The computer-implemented method of claim 6 wherein the indication includes a second label that is different from the label, and modifying the particular label comprises replacing the label with the second label.
number: 8
text: The computer-implemented method of any preceding claim further comprising:
number: 9
text: The computer-implemented method of any preceding claim wherein the data representing the sensor measurement represent at least one object in the vicinity of at least one roadway.
number: 10
text: One or more non-transitory computer-readable storage media storing instructions that when executed by one or more computers cause the one or more computers to perform operations comprising the method of any of claims 1-9.
number: 11
text: A system comprising one or more computers and one or more storage devices storing instructions that when executed by the one or more computers cause the one or more computers to perform operations comprising the method of any of claims 1-9.
