2022 Yangtze River Delta mathematical modeling: Gearbox Fault Diagnosis

Train of thought guide

Just look at this part directly , It's misleading to read too much ：

First question

Data analysis , Read data first ：

      
      

       
       import 
       
       pandas 
       
       as 
       
       pd
       
       

       
       

       
       df
       
       =
       
       pd.
       
       read_excel(
       
       ' The attachment 1.xls')
       
       

       
       

       
       df.
       
       head(
       
       10)

Follow up on your own … You know ： Sichuan rookie , It will be updated later .

Second questions

Second questions ：

That's the judgment based on the first question , Judge whether the data in Annex I is faulty , Evaluate the performance according to these indicators , Evaluation model .

Third questions

Pay attention to see clearly , Build a model to judge what state the data is in , Make another evaluation , This data should be arbitrary , Not necessarily Annex I , But it seems that we can only evaluate the test from the first attachment . It's different from the second question .

Fourth question

Synthesize the previous two questions , Analysis Annex II ：
