Abstract: A single policy can be trained to handle the user selection of parameters across a predetermined range for each component of an artificial intelligent agent within a domain. The agent can be trained across a number of weights within the desired range for each component. These weights determine how much of a reward portion for each component should be considered by the agent during training. Thus, an improved formulation can be realized for UVFA-like goals based on compositional reward functions parameterized by their components' weights. Additionally, a set of reward components has been determined for the domain of autonomous racing games that, when combined with the improved UVFA formulation, allows training a single racing agent that generalizes over continuous behaviors in multiple dimensions. This can be used by game designers to tune the skill and personality of a trained agent.

Abstract: A substantially fluid impermeable textile graft may be produced by selective application of a substantially water-soluble material or masking agent, and optionally selective removal of excess substantially water-soluble material, followed by the application of a substantially water-insoluble sealant. The inner surface of the graft includes a coating of the substantially water-soluble material thereon. The outer surface includes a coating of the substantially water-insoluble sealant disposed thereon. The tubular wall having the coating of the substantially water-insoluble sealant is, after curing thereof, substantially impermeable to liquid. The substantially water-soluble material is removed from the graft after the application of the substantially water-insoluble sealant.
