Claim 2:
3. A data collecting method for machine learning that collects teacher data or test data of a classification model that classifies a class by machine learning, the data collecting method comprising:
classifying each of a plurality of recorded, learned classification models using data with a label transmitted from a user environment as input data;
presenting an appropriate classification model for the input data to the user environment based on a classification result for each of the classification models, and storing a classification result including at least one of classification correctness or a percentage of correct answers for each input data;
presenting the classification correctness to a user;
detecting whether the classification model is employed or not in the user environment;
recording the input data as teacher data or test data of the classification model when the classification model is employed in the user environment; and
correcting a label of the input data, wherein input data on which the correctness result is reflected is recorded;
wherein the user environment is contained in a machine tool;
the user environment including a machining data obtaining unit for obtaining data during processing by the machine tool;
a machining data storing unit for recording processing data collected by the machine data obtaining unit;
a classification model storing unit for storing a learned classification model for determining a presence or absence and type of abnormality; and
a classification executing unit for determining the presence or absence of abnormality in processing of the machine tool using the learned classification model stored by the classification model storing unit;
wherein a determination result of the presence or absence of abnormality is transmitted to the machine tool to execute a control of machining by the machine tool; and
wherein the processing data recorded by the machining data storing unit is labeled and transmitted to the data collection system to be classified.
