Abstract: Techniques are provided for using machine learning techniques to identify predictive features and predictive values for each feature. In one technique, a model is trained based on training data that comprises training instances, each of which corresponds to multiple usage-based features of an online service by a user. For each usage-based feature in a subset of the usage-based features, the model is used to generate a dependency graph, a histogram is generated, and an optimized value is selected based on the dependency graph and the histogram. A user of the online service is identified, along with a usage value that indicates a level of usage, by the user, of a usage-based feature. A comparison between the usage value and an optimized value of the usage-based feature is performed. Based on the comparison, it is determined whether to present data about that usage-based feature to the user.

Abstract: In one embodiment, described herein is a system and method for filtering obstacles to reduce the number of obstacles for an autonomous driving vehicle (ADV) to process in a given planning phase. The ADV can identify a first set of obstacles based on a set of criteria in a first lane where the ADV is travelling, filter out the remaining obstacles in the first lane, and expand each identified obstacle to a width of the first lane from the view of the ADV so that the ADV cannot nudge any of the first set of identified obstacles. When switching from the first lane to a second lane, the ADV can identify a second set of obstacles in the second lane using the same set of criteria, and expand each obstacle in the second set of obstacles to a width of the second lane while keep tracking the first set of identified obstacles. When the lane switching is completed, the ADV can stop tracking the first set of identified obstacles.
