Learning data confirmation support device, machine learning device, and failure predicting device

Abstract

To facilitate confirmation as to whether or not it is data measured by the same operation upon acquiring measurement data in an industrial machine. A learning data confirmation support devicethat facilitates confirmation of contamination of inappropriate data when learning data including only normal data are acquired in advance, in order to detect an anomaly of an industrial machine using machine learning, includes a data acquisition unitthat acquires measurement data including time-series data representing at least one of a predetermined state quantity or control quantity relating to control when the industrial machine is made to perform a certain operation; and a display control unitthat aligns a plurality of pieces of time-series data acquired by the data acquisition unit in a direction of a time axis and, in this state, superimposes a same type of pieces of data of the time-series data to display in a graph.
