Once you have trained an AI model, the next step is to test it to see how well it performs. Testing allows you to check if the model can correctly make predictions on new, unseen data and if it is ready to be used in real-world scenarios. It is an important part of ensuring that your model works as expected.

1. Use Unseen Data (Test Set):
   When testing, make sure to use a separate dataset from the one you used for training. This is called the “test set.” The test set should consist of data that the model has never seen before. This helps to check if the model can generalise its learning to new data.
2. Evaluate the Results:
   After testing, look at how the model performed on the test data. Did it correctly identify the objects or make accurate predictions? If the model performs well, it’s ready to be used. If the results aren’t good, you may need to adjust the model, add more data, or improve the training process.

Testing is crucial to make sure that your AI model is effective and ready to be used. By using unseen data and evaluating the model’s performance, you can confidently determine how well your AI works.
