Classification: CPC G  H | IPC G

Claim 6:
7. A diagnosis system that diagnoses a state of a device for measuring or inspecting a sample, the diagnosis system comprising:
a computer system configured to estimate a cause for an error occurring in the device,
wherein the computer system includes a learning device configured to learn, by machine learning, a correspondence between at least one of a recipe that defines an operation of the device, log data that describes the state of the device, or sample data that describes characteristics of the sample and a type of the error,
when the error occurs in the device after the learning device executes the machine learning, the computer system inputs at least one of the recipe used by the device when the error occurs, the log data when the error occurs, or the sample data when the error occurs to the learning device, so as to acquire an estimation result for at least one cause of the recipe, the state of the device, or the characteristics of the sample among the causes for the error as an output of the learning device and to output the estimation result,
wherein the learning device includes
a first learning unit configured to learn a correspondence between the recipe and the type of the error,
a second learning unit configured to learn a correspondence between the log data and the type of the error,
a third learning unit configured to learn a correspondence between the sample data and the type of the error, and
a fourth learning unit configured to learn a correspondence between an estimation result by the first learning unit, an estimation result by the second learning unit, an estimation result by the third learning unit, and the type of the error,
wherein the learning device outputs the estimation result by each of the first learning unit, the second learning unit, the third learning unit, and the fourth learning unit as an output of the learning device.
