Classification: CPC G  H | IPC G

Claim 3:
4. 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 when the estimation result of the cause for the error is a known cause, the computer system corrects at least one of the recipe or the state of the device and acquires a reinspection result from the device, and
when the reinspection result is normal, the computer system relearns that the error does not occur in association with at least one of the recipe used by the device when the reinspection result is acquired, the log data when the reinspection result is acquired, or the sample data when the reinspection result is acquired.
