A computer-implemented method for localizing a vehicle can include accessing, by a computing system comprising one or more computing devices, a machine-learned retrieval model that has been trained using a ground truth dataset comprising a plurality of pre-localized sensor observations. Each of the plurality of pre-localized sensor observations has a predetermined pose value associated with a previously obtained sensor reading representation. The method also includes obtaining, by the computing system, a current sensor reading representation obtained by one or more sensors located at the vehicle. The method also includes inputting, by the computing system, the current sensor reading representation into the machine-learned retrieval model. The method also includes receiving, by the computing system and from the machine-learned retrieval model, a determined current pose value for the vehicle based at least in part on one or more of the pre-localized sensor observations determined to be a closest match to the current sensor reading representation. The determined current pose value has an accuracy of within about one meter.
