Zero Shot Learning
Zero Shot
Zero Shot is a natural language processing technique that allows intelligent agents to recognize features that have not been previously trained. Zero Shot requires no training data, allowing you to shorten the AI creation process and classify sentences quickly and accurately. Its biggest benefits are: increased customer adoption, better understanding during the conversation with the end user and greater ease in implementing AI in new projects.
Some important information about the model:
- ZeroShot ranks higher in Portuguese, Spanish and English compared to the current market leaders:
Zero Shot | 78.4% Accuracy |
GPT-4-Turbo | 76.8% Accuracy |
Claude 3 (Sonnet) | 77.6% Accuracy |
- At least 3x faster in classification (inference);
- Efficient model included in your Weni plan, without the need for API calls or additional costs;
- Easy and quick implementation.

Application and Features
The way the Zero Shot application works consists of receiving as input a phrase, which will be categorized, and identifying which category this input belongs to according to the customer's context. Categories are defined through Command Phrases, which serve as context to identify and generate the correct classification. From the input data, the model is expected to return the category of the sentence.
When we talk about context, take into account that whenever you use Zero Shot, we must configure the Command Phrases. Command phrases will instruct the intelligence to classify your intentions (called "Classes") according to rules defined by you.
Zero Shot in Practice
There are two ways to create a Zero Shot classification AI on the Weni Platform: through the Classify automatically and Smart Wait for response flow cards.
Smart Wait for response
With the Smart Wait for response card, you can wait for the user's response and send that response directly to your AI Classification, so you can create your categories and treat each intention as you wish:
In the example below, we create intentions and their appropriate contexts so that we can categorize and handle user requests:
Remember, each category must have a Command Phrase. The command phrases will instruct the intelligence and you can use these examples:
Automatic Classiffy
With the Automatic classify card, you can use an expression or variables as the input for classifying user intent (Class). This card is normally used when you already have a text to deal with and do not need to wait for a response from the user before consulting Artificial Intelligence:
Use Cases
Example use case for client context in the financial area:
categories: [{"class":"HumanAssistance","context":"When the user wants to speak with an attendant or human specialist."},
{"class":"Invoice","context":"When the user wants to generate a new payment invoice"},
{"class":"Statement","context":"When the user wants to see their financial status"},
{"class":"Debts","context":"When the user wants to access or renegotiate their debts."}]
expected result: "HumanAssistance"
Example use case for client context in the educational area:
categories: [{"class":"Calendar","context":"When the user wants to know the class schedule."},
{"class":"Subjects","context":"When the user needs to access information about the subjects."},
{"class":"Scores","context":"When the user requests access to their scores"},
{"class":"Teachers","context":"When more information about the teachers is requested."}]
expected result: "Scores"
