Abstract: System, methods, and other embodiments described herein relate to improving vehicle routing for a mobility service. In one embodiment, a method includes, in response to receiving a routing request for the mobility service, determining candidate vehicles and candidate routes for the candidate vehicles to fulfill the routing request. The method includes evaluating the candidate routes using a meta-heuristic that modifies and assesses the candidate routes according to at least a fitness function defines attributes for constraining the candidate routes. The method includes providing a solution route from the candidate routes upon the solution route satisfying at least one solution condition.

Abstract: An example operation includes one or more of receiving utterances from a user via an input device, identifying a plurality of sentences spoken by the user from the utterances, converting the utterances into a sequence of tokens and storing the sequence of tokens within a data structure, wherein the storing comprises adding padding tokens to the data structure in between the sequence of tokens to normalize a structure among the plurality of sentences within the data structure, executing a machine learning model on the data structure with the added padding tokens to determine to make a prediction, removing the padding tokens from the data structure, and executing a natural language processing (NLP) model on the sequence of tokens within the data structure with the padding tokens removed to determine a response to the user.

Abstract: An example operation includes one or more of receiving an utterance from a user which is associated with a task, determining, via a machine learning model, that not enough information is available to determine an action based on the utterance, initiating, via a virtual assistant, a dialog with the user and receiving one or more additional utterances from the user via the input device, determining, via the machine learning model, that enough information is available for accomplishing the action based on the one or more additional utterances, determining, via the machine learning model, a task to be performed based on the utterance and the one or more additional utterances, and transmitting an instruction to a system to perform the task.
