Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If current AI tools implement vague corrective utterances or extremely specific corrective instructions, then the AI tools can automatically generate language corrections to a human user, but the corrections do not provide helpful content for training a human user to improve a skill
Solution Approach 1:
The system changes the parameters of corrective feedback by transitioning from vague utterances or overly specific instructions to structured teaching actions with multiple granularity levels. The teacher action model generates corrections that are neither too vague nor too specific, but appropriately tailored to facilitate skill learning by adjusting the information content and instructional depth of the feedback.
Solution Approach 2:
The system implements a feedback mechanism where the AI model generates teaching actions that provide constructive guidance to drivers. The feedback loop includes generating teaching actions based on detected driving behaviors, delivering these actions to the driver, and using the results to continuously improve the model's ability to generate helpful corrections that actually advance driver skills.
2Adaptability or versatility
If AI tools focus on learning control policies that incorporate natural language feedback from users, then the AI tools can carry out interactions with a human user to influence human behavior, but the AI tools fail to provide actionable feedback that improves driver skills
Solution Approach 1:
The system applies local quality by providing differentiated feedback based on the specific driving context and the particular skill being developed. Rather than using generic natural language feedback, the teacher action model generates context-specific teaching actions that are tailored to the immediate driving situation and the driver's current skill level, making the feedback locally optimized for skill improvement.
Solution Approach 2:
The system segments the feedback into structured teaching actions with different components and granularity levels. Instead of providing undifferentiated natural language feedback, the system breaks down corrections into actionable teaching actions that address specific aspects of driving behavior, allowing drivers to focus on and improve particular skills through targeted feedback.
3Adaptability or versatility
If the system encodes driving data from multiple driving scenarios including instructed and uninstructed events, then the AI model can learn from diverse data, but the system must process and analyze complex varied data to determine driving skill transitions
Solution Approach 1:
The system achieves universality by creating a unified encoding framework that handles multiple types of driving scenarios (instructed and uninstructed events) through a common processing pipeline. The behavior model and trajectory estimator are designed to process diverse driving data uniformly, extracting skill transitions across different scenario types without requiring separate specialized processing for each event type.
Solution Approach 2:
The system introduces intermediate processing components (behavior model, trajectory estimator) that act as mediators between the raw diverse driving data and the skill transition determination. These intermediary models transform complex varied data into structured representations that capture essential skill transitions, simplifying the overall processing complexity while maintaining the ability to learn from diverse scenarios.
Data Source
AI summary
A teaching curriculum method for generating teaching actions for drivers, includes obtaining driving data from a plurality of driving scenarios, the driving data comprises vehicle trajectory information and corresponding scene context information, the driving scenarios comprising instructed driving events and uninstructed driving events, encoding, with a behavior model, the driving data, wherein the encoded driving data comprises an indication that a corresponding one of the driving scenarios comprises one of the instructed driving event or the uninstructed driving event, determining, with a trajectory estimator processing the encoded driving data, one or more driving skill transitions based on a presence or an absence of the indication, and generating, with a teacher action model, a teaching action for one of the plurality of driving scenarios.
