1. A system comprising: a touch surface configured to receive a plurality of inputs; one or more processors communicatively coupled to the touch surface; and memory storing instructions that, when executed by the one or more processors, cause the system to: implement a first classifier to evaluate information associated with a first input and a second input to determine whether the second input is an intended touch input or an unintended touch input, wherein the first classifier evaluates the information to determine an inter-arrival distance between a first position at which the first input arrives at the touch surface and a second position at which the second input arrives at the touch surface; and in response to the first classifier being unable to determine whether the second input is the intended touch input or the unintended touch input, implement at least one subsequent classifier to evaluate additional information to determine whether the second input is the intended touch input or the unintended touch input, wherein the additional information evaluated is associated with a movement of the first input relative to a movement of the second input.
