Publication number: 20240367685Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing rare example mining in driving log data. In one aspect, a method includes obtaining a sensor input; processing the sensor input using an encoder neural network to generate one or more feature vectors for the sensor input; processing each of the one or more feature vectors using a density estimation model to generate a density score for the feature vector; and generating a rareness score for each of the one or more feature vectors from the density score. For example, the rareness score can represent a degree to which a classification of an object depicted in the sensor input is rare relative to other objects. As another example, the rareness score can represent a degree to which a predicted behavior of an agent depicted in the sensor input is rare relative to other objects.Type: ApplicationFiled: May 2, 2023Publication date: November 7, 2024Inventors: Wilson Zhao, Chiyu Jiang

Publication number: 20240370695Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing rare example mining in driving log data. In one aspect, a method includes maintaining a plurality of density estimation models that each correspond to a different rareness type with respect to historical sensor inputs in a driving log generated by sensors on-board a vehicle; receiving a query that references a sensor input; generating, from the sensor input, a corresponding density estimation model input for each of the plurality of density estimation models; processing, using each of the plurality of density estimation models, the corresponding density estimation model input to generate a corresponding density score; generating, for the sensor input, and from the density scores, a rareness score associated with each different rareness type; and providing the rareness scores in response to receiving the query.Type: ApplicationFiled: May 2, 2023Publication date: November 7, 2024Inventors: Wilson Zhao, Chiyu Jiang

Patent number: 11915387Abstract: Implementations relate to crop yield prediction at the field- and pixel-level. In various implementations, a first temporal sequence of high-elevation digital images may be obtained that capture a first geographic area and are acquired over a first predetermined time interval while the first geographic area includes a particular crop. A first plurality of other data points may also be obtained that influence a ground truth crop yield of the first geographic area after the first predetermined time interval. The first plurality of other data points may be grouped into temporal chunks corresponding temporally with respective images of the first temporal sequence. The first temporal sequence and the temporal chunks of the first plurality of other data points may be applied, e.g., iteratively, as input across a machine learning model to estimate a crop yield of the first geographic area at the end of the first predetermined time interval.Type: GrantFiled: April 21, 2023Date of Patent: February 27, 2024Assignee: MINERAL EARTH SCIENCES LLCInventors: Cheng-en Guo, Wilson Zhao, Jie Yang, Zhiqiang Yuan

Patent number: 11900560Abstract: Implementations relate to diagnosis of crop yield predictions and/or crop yields at the field- and pixel-level. In various implementations, a first temporal sequence of high-elevation digital images may be obtained that captures a geographic area over a given time interval through a crop cycle of a first type of crop. Ground truth operational data generated through the given time interval and that influences a final crop yield of the first geographic area after the crop cycle may also be obtained. Based on these data, a ground truth-based crop yield prediction may be generated for the first geographic area at the crop cycle's end. Recommended operational change(s) may be identified based on distinct hypothetical crop yield prediction(s) for the first geographic area. Each distinct hypothetical crop yield prediction may be generated based on hypothetical operational data that includes altered data point(s) of the ground truth operational data.Type: GrantFiled: December 27, 2022Date of Patent: February 13, 2024Assignee: MINERAL EARTH SCIENCES LLCInventors: Cheng-en Guo, Wilson Zhao, Jie Yang, Zhiqiang Yuan, Elliott Grant
