1. A method for executing an assistant on a computing device to determine whether or not to act, the method comprising:

  • receiving, by the assistant, streaming evidence from one or more sensors;

    constructing, by the assistant, one or more belief projection models to predict a future belief over a state at a future time, the one or more belief projection models using existing evidence that is collected until a defined period of time to determine a probability of a future state that is based on evidence to be collected between the defined period of time and the future time, the existing evidence comprising the streaming evidence and other evidence obtained prior to the streaming evidence;

    based on the predicted future belief and the one or more belief projection models, determining, by the assistant device, a likelihood of obtaining particular evidence between the defined period of time and the future time to determine whether to act at the defined period of time for a next action or wait for the future time to act for the next action; and

    based on determining to act at the defined period of time or wait for the future time to act for the next action, transmitting, by the assistant device, data using an output device at the defined period of time without obtaining the particular evidence or upon receipt of the particular evidence at the future time.
