Abstract: A method, apparatus, and non-transitory computer-readable medium for generating a hypothesis from a knowledge graph. The method comprises processing the knowledge graph comprising a plurality of fact triples. Each fact triple of the plurality of fact triples comprises two concepts of a set of concepts and one relationship of a set of relationships. Each fact triple is also associated with at least one source. The method further comprises generating the hypothesis from data representing multiple triples, the hypothesis. The hypothesis includes at least one predicted triple having a concept-concept relationship not found in the knowledge graph. The method then outputs at least one source and/or explanation data for the hypothesis.

Abstract: A powertrain for an electric bicycle has: an electric motor; a motor gear driven by the electric motor; a crankshaft adapted for connecting to crank arms; an input shaft having first and second end portions, the second end portion driven by the crankshaft; an input gear connected to the first end portion and being driven by the motor gear, the input gear driving the input shaft; at least one first gear mounted to the input shaft; an output shaft; at least one second gear mounted to the output shaft and being driven by the at least one first gear; a drive sprocket driven by the output shaft; and a torque sensor disposed between the second end portion and the at least one first gear for sensing torque applied to the input shaft. The electric motor is controlled based at least in part on torque sensed by the torque sensor.
