In various examples, a technique for recommending items is disclosed that includes receiving a request to recommend an item. The technique further includes generating, based on the request, one or more query tags, the one or more query tags including one or more preferred tags, at least one of the preferred tags specifying an item of interest. The technique also includes generating one or more subqueries based on the one or more query tags. The technique still further includes generating, based on the one or more subqueries, a query vector in an embedding space of the vector database. The technique further includes identifying, in the vector database and using the query vector, a plurality of candidate items. The technique still further includes selecting a recommended item from the plurality of candidate items based on the request.

Recommendation system using retrieval-augmented generation

In various examples, sensor data representative of an image of a field of view of a vehicle sensor may be received and the sensor data may be applied to a machine learning model. The machine learning model may compute a segmentation mask representative of portions of the image corresponding to lane markings of the driving surface of the vehicle. Analysis of the segmentation mask may be performed to determine lane marking types, and lane boundaries may be generated by performing curve fitting on the lane markings corresponding to each of the lane marking types. The data representative of the lane boundaries may then be sent to a component of the vehicle for use in navigating the vehicle through the driving surface.

Real-time detection of lanes and boundaries by autonomous vehicles

In various examples, a path perception ensemble is used to produce a more accurate and reliable understanding of a driving surface and/or a path there through. For example, an analysis of a plurality of path perception inputs provides testability and reliability for accurate and redundant lane mapping and/or path planning in real-time or near real-time. By incorporating a plurality of separate path perception computations, a means of metricizing path perception correctness, quality, and reliability is provided by analyzing whether and how much the individual path perception signals agree or disagree. By implementing this approach—where individual path perception inputs fail in almost independent ways—a system failure is less statistically likely. In addition, with diversity and redundancy in path perception, comfortable lane keeping on high curvature roads, under severe road conditions, and/or at complex intersections.
