An autonomous vehicle (AV) can utilize quantitative data, such as data received from sensors with known intrinsic parameters (e.g., positive data) to determine a second subsequent action from a set of possible actions, using inputs such as an original subsequent action. To improve the decision-making process of the second subsequent action, the AV can utilize qualitative data, such as data received from a data storage system (e.g., negative data). Qualitative data can be text or image based, such as from a crash report or sensor data missing sufficient intrinsic parameters to make a quantitative evaluation. By weighting the quantitative data against the qualitative data, the decision-making process of the AV towards its high-level goal (such as moving toward a parking lot) can be more efficient, such as ensuring lower levels goals are met. The decision process can utilize multi-modal large language models and latent space models to weight data appropriately.

Systems and methods for extracting rule lists from tree ensembles are provided. A system extracts first stage candidate rules from individual trees. The system identifies the first stage candidate rules that satisfy a precision threshold and places those rules in a solution set.
