The machine learning model may generate an output based on the second contextual data and at least a portion of the first contextual data.

Abstract: Systems and methods are provided to perform retrieval-augmented generation for machine learning models using filtered contextual data. A system can identify data associated with a machine learning model. The data may be associated with one or more first identifiers that may indicate a user, a user computing device, a model, etc. associated with the data. In response to determining that the data satisfies one or more parameters, the system can identify a need for contextual data. The system can compare the one or more first identifiers associated with the data to one or more second identifiers associated with the contextual data. Based on the comparison, the system can filter the contextual data to obtain filtered contextual data. The system may provide the filtered contextual data to the machine learning model for generation of an output.

Abstract: A method for training a machine learning (ML) model for generating a joint particle-based representation of a scene from multi-modality sensor data. The method includes receiving sensor data acquired by a set of optical sensors of different sensor modality, representing the same scene. A joint particle-based representation of the scene covered by the optical sensors is generated. Intersections between rays emanating from a sensor location with the joint particle-based representation are determined, based on which an observation of the scene is rendered. A sensor-specific loss function value is determined by comparing the rendered observation with an observation rendered based on the received sensor data. The ML model is trained by determining the intersections, rendering the observation and determining the value of the sensor-specific loss function for every optical sensor, and by optimizing a combination of the sensor-specific loss functions.
