====Rebuilding an AI Model=====

If you've made changes to your data and would like to re-train your [[start|AI anomaly detector]] to take advantage of extra context information, you'll need to **erase** and **rebuild** your model.

===Backing Up Training Data===

//This step is optional, but recommended when the AI you're rebuilding has several different training data samples.//

When signed in as an Administrator, open the anomaly display from the asset dashboard.

Then click **Training Data** and **Download Sample Times**.

This downloads a CSV file containing the start and end times of each historical period you're using to train your AI model.

===Erasing a Model===

You can erase an AI anomaly detector model by signing in as an Administrator and choosing **AI Anomaly Detector** in the asset dashboard.

Then press the **Erase Model** button to clear the AI.

===Re-Create the Model===

Follow the [[walkthrough|normal process]] of creating a new AI.

===Upload Sample Data===

//This step is only needed if you backed up your sample times in step 1//.

Next, choose **Training Data** and then **Upload Sample Times**.

Choose the file you downloaded in step 1 and press 'Add Training Data'.

This will then upload the list of sample times - the addon will then re-download the training data and re-train the AI.
