In the world of machine learning, predictions can often be represented by numerical values that require transformation for analysis or decision-making. This article will walk you through a simple code snippet that rotates prediction values from one category to another.

Understanding the Code

The provided code snippet performs a transformation on a list of predictions, changing each prediction value based on specific rules. Here’s the code:

for i in range(len(predictions)):  
    if predictions[i] == 0:    
        predictions[i] = 2  
    elif predictions[i] == 1:    
        predictions[i] = 0  
    elif predictions[i] == 2:    
        predictions[i] = 1

Imagine you are at a circular playground with three distinct swings labeled 0, 1, and 2. As you approach the swings, you decide to switch to the adjacent swing based on the current one you’re on:

• If you’re on swing 0, you hop over to swing 2.
• If you’re on swing 1, you transition back to swing 0.
• If you’re on swing 2, you swing forward to swing 1.

This rotating shift allows each prediction to transform into a different value, essentially scramblig your original predictions while maintaining an organized flow. Now, let’s delve into how to implement this.

How to Implement the Prediction Transformation

1. Start by defining your list of predictions. This could be an outcome from a model predicting different classes.
2. Utilize the provided loop to access each prediction in the list.
3. Apply the conditional transformations as described to change the values in place.
4. After running this loop, your original predictions will be successfully transformed!

Troubleshooting Tips

While implementing this code, you may run into a few common issues:

• IndexError: Ensure that your predictions list is not empty. An attempt to access an index in an empty list will throw an error.
• Unexpected Results: Make sure that all values in the predictions list are either 0, 1, or 2. Values outside this range will remain unchanged.
• If you find that the code is not working as expected, double-check your logical conditions for transformation.
