Cause When a KNN model is logged, all of the data points used for training are saved as part of the pickle file. If the model is trained with millions of records, all of that data is added to the model, which can dramatically increase its size. A model trained on millions of records...
When training a KNN model using the /_plugins/_knn/models/{model_name}/_train POST endpoint, often the error message returned by GET /_plugins/_knn/models/{model_name} just says Failed to execute training. May be caused by an invalid met...
I am putting together a KNN model and and have it setup to run a Model Comparison node to run K= 5 - 15.I have the Model Comparison node to show Misclassification Rate and Validation instead of Train. When I run the model it goes well but in the Report section and in the O...
These accuracy metrics compare the model predictions for their respective task to the ground truth provided by the empirical test data. To find the best model that reports the highest accuracy or lowest error on the test dataset, run a hyperparameter tuning job for k-NN. Automatic model ...

This example shows how to build a KNN model on the CUSTOMER_CHURN sample data set. First, you create the CUSTOMER_CHURN_VIEW sample data set that is based on the CUSTOMER_CHURN table as follows: CREATE VIEW CUSTOMER_CHURN_VIEW AS (SELECT CUST_ID, DURATION, CASE WHEN CENSOR=1 THEN '...
