1. A system in a vehicle, the system comprising: a display interface; a perception system configured to receive data indicative of a surrounding environment of the vehicle, and to classify one or more portions of the data as being representative of a particular type of object based on parameters associated with a machine learning classifier, wherein the data indicative of the surrounding environment comprises point cloud data that is representative of the object; and a feedback system configured to determine a confidence level associated with the classification by the perception system based on a relationship between features extracted from the point cloud data and expected characteristics of features for the particular type of object, to request via the display interface feedback from a user of the vehicle regarding the classification by the perception system responsive to determining that the confidence level is below a threshold, and to cause the parameters associated with the machine learning classifier to be modified based on information provided by the user in response to the request.
