F1 score
The F1 score is a function of Precision and Recall. The score is needed when you seek a balance between precision and recall.
Intent
An intent represents a task or action the user wants to perform. It's a purpose or goal expressed in a user's input, such as booking a flight, or paying a bill.
Model
A model is an object trained to do a certain task, in this case conversation understanding tasks. Models are trained by providing labeled data to learn from so they can later be used to understand utterances.
- Model evaluation is the process that happens right after training to know how well does your model perform.
- Deployment is the process of assigning your model to a deployment to make it available for use via the prediction API.
Overfitting
Overfitting happens when the model is fixated on the specific examples and isn't able to generalize well.
Precision
Measures how precise/accurate your model is. It's the ratio between the correctly identified positives (true positives) and all identified positives. The precision metric reveals how many of the predicted classes are correctly labeled.
Project
A project is a work area for building your custom ML models based on your data. Your project is only accessible for you and others who have access to the Azure resource being used.
Recall
Measures the model's ability to predict actual positive classes. It's the ratio between the predicted true positives and what was tagged. The recall metric reveals how many of the predicted classes are correct.
Schema
Schema is defined as the combination of intents within your project. Schema design is a crucial part of your project's success. When creating a schema, you want to think about which intents should be included in your project
Training data
Training data is the set of information that is needed to train a model.
Utterance
An utterance is a short text representative of a sentence in a conversation. It's a natural language phrase such as "book two tickets to Seattle next Tuesday." Example utterances are added to train the model and the model predicts on new utterance at runtime
