Extensions

Instruction Page: Extensions for Your Agent

In this section, we encourage you to think beyond the basic requirements and implement extensions that enhance your agent’s capabilities, user experience, or sophistication. The more creative, innovative, or technically challenging your design ideas are—and the better your implementation—the more credit you will receive.

Even if your extension isn't fully functional or has issues during testing, you can still earn points by explaining your choices, identifying limitations, and proposing fixes in your report. Justify your extensions and provide a clear breakdown of their implementation and evaluation.

Below, we provide suggestions for potential extensions. These are for inspiration only, and you are encouraged to explore ideas beyond this list.

1. Extensions for Dialogue Patterns

To make your agent more conversational and engaging, consider the following:

Refine Responses

• What? Improve the variety, context, and relevance of your agent's responses to avoid repetitiveness and make the agent sound less robotic.

• How?

  • Add multiple example phrases for the same response in the responses.pl file using tools like ChatGPT or manual input.

  • Contextualize responses to specific conversation states, such as providing helpful recovery prompts for misunderstood queries.

• Ideas:

  • Use best practices for repair (e.g., from Google) to refine recovery prompts.

  • Provide more specific feedback during breakdowns, explaining what aspect of the query was unclear or suggesting alternative ways to phrase the request.

  • Enable user-initiated repair, allowing the agent to respond appropriately when users express confusion (e.g., “What do you mean by ‘X’?”).

Introduce Small Talk

• What? Make the agent more engaging by adding small talk capabilities related to the recipe domain.

• How?

  • Add new intents and patterns for small talk initiated by either the user or the agent.

  • Example: The agent could respond to "What’s your favorite recipe?" with a lighthearted answer.

Restart Conversation

• What? Allow the user to restart the conversation at any point.

• How? Add new patterns and intents to handle restart requests.

Enhance Personality

• What? Shape the agent’s responses to reflect a particular personality, conversational style, or social characteristics.

• How? Design responses to convey friendliness, humor, or formality based on user interactions.

• Note: Gordon Ramsey is overdone. Avoid strong stereotypes, think about the ethicality of agent personalities.

2. Extensions for Visual Support

While the primary interaction should remain conversational, visuals can enhance the user experience by providing supplementary information. Consider these ideas:

Extend Visuals

• What? Make visuals more useful by adding interactive or informative elements.

• How?

  • Show a visual progress tracker indicating how far the user has progressed in recipe filtering.

  • Add a filtering history view, allowing users to see and review their past selections.

  • Include a rating system to collect user feedback on the agent’s performance.

3. Extensions for Recipe Filtering and Capabilities

Extend the recipe filtering and selection logic to include new capabilities:

Add More Recipe Filters

• What? Add new filters for recipe attributes not currently supported (e.g., easy recipes, fast recipes, preparation time, number of steps).

• How? Update the recipe_selection.pl file to include the new logic and entities, using attributes from the recipe_database.pl file.

Check Ingredients

• What? Add functionality to verify whether the user has all required ingredients before confirming a recipe.

• How? Create new patterns and intents for ingredient checks, and potentially update visuals to prompt users to verify their pantry.

Additional Features

• Read Out Steps: Add a capability for the agent to read out recipe steps interactively.

• Indicate Servings: Include serving size information in the recipe details.

4. Extensions for Intent and Slot Classification

Enhance the performance of your intent and slot classifier:

Fallback to Probability Threshold

• What? Add a fallback mechanism for classification confidence.

• How?

  • Use a probability threshold to identify low-confidence predictions and trigger fallback responses or recovery prompts.

Classifier Improvements

• What? Improve classification performance by applying techniques from Model Improvement.

• How?

  • Experiment with hyperparameter tuning, training augmentation, or model augmentation to optimize your classifier.

Your Creativity Counts

These suggestions are starting points—your agent is a platform for innovation. Explore ideas that resonate with you and enhance the user experience. Be creative, justify your choices in your report, and strive for thoughtful implementation and testing. Even if some ideas don't fully succeed, demonstrating your problem-solving process will earn you credit.
