Inference apparatus and learning apparatus

An inference apparatus comprising:

• processing circuitry
• to compute, as a shape similarity, a similarity in shape between a learning movement path curve which is a movement path curve obtained through learning and an observation movement path curve which is a movement path curve obtained through observation;
• to compute, as a position similarity, a similarity in position between the learning movement path curve and the observation movement path curve when the learning movement path curve and the observation movement path curve are placed in a same coordinate space;
• and
• to compute a conformity between the learning movement path curve and the observation movement path curve, using the shape similarity and the position similarity, wherein
• the learning movement path curve is divided into a plurality of curve components constituting the learning movement path curve,
• the observation movement path curve is divided into a plurality of curve components corresponding to the plurality of curve components of the learning movement path curve, and
• the processing circuitry
• computes the shape similarity for each pair of corresponding curve components between the learning movement path curve and the observation movement path curve,
• computes the position similarity for each pair of corresponding curve components between the learning movement path curve and the observation movement path curve, and
• sets a significance level for each curve component of the learning movement path curve based on an attribute of each curve component, and
• computes the conformity, using the shape similarity, the position similarity, and the significance level of each curve component.
