Assignee: TOKYO ELECTRON LIMITED
Field: Chemical engineering (Chemistry)
Classification: CPC G  B | IPC B  G

Claim 10:
11. The abnormality detection apparatus of claim 1, wherein the first generation part is further configured to generate multiple pieces of pseudo-normal image data by synthesizing a substantially circular image at a random position of an image for each of multiple pieces of normal image data obtained by photographing a series of operations of the equipment that operates without an abnormality,
wherein the second generation part is further configured to generate the determination model for determining whether the equipment is normal or abnormal by performing learning of the multiple pieces of normal image data and the multiple pieces of pseudo-abnormal image data,
wherein the acquisition part is further configured to acquire multiple pieces of image data obtained by photographing a series of operations of the equipment, and
wherein the detection part is further configured to determine whether the multiple pieces of image data acquired by the acquisition part are normal or abnormal using the determination model, and detect that an abnormality has occurred in the equipment when any of the multiple pieces of image data is determined to be abnormal.
