Understand how to measure the performance of each API model and metrics, and how to calculate each metric.
The NLU service uses various metrics to show the performance and characteristics of the model. The correct interpretation of these metrics is vital to utilize the full power of NLU.
The overall metrics we use in NLU are
You can train a model by clicking the 'Train Model' button on the top right corner of the Dashboard. The training process ends with measuring the model's performance using the samples you marked as 'Test' in the Dashboard tab page [Image 1].
