Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual evaluation methods are used to assess tutors, then human judgment and flexibility can be applied, but the process becomes inefficient, time-consuming, and prone to bias
Solution Approach 1:
The patent replaces manual human evaluation with an automated machine learning system that uses natural language processing to analyze tutor responses. The system automatically scores and evaluates tutors based on predefined criteria, eliminating human bias and significantly improving evaluation efficiency while maintaining reliability through consistent, objective assessment across all tutors
Solution Approach 2:
The evaluation system performs self-assessment by automatically analyzing tutor performance data, generating evaluations, and providing feedback without requiring manual human intervention. The machine learning model continuously learns from evaluation data and improves its assessment capabilities autonomously, making the system both efficient and reliable
2Speed
If real-time automated evaluation is implemented, then evaluation speed and responsiveness improve, but system complexity and computational requirements increase
Solution Approach 1:
The evaluation system is divided into modular components including natural language processing modules, scoring algorithms, and feedback generation systems. Each module handles specific aspects of evaluation independently, enabling real-time processing while keeping individual components manageable in complexity. The segmented architecture allows parallel processing of multiple tutor evaluations simultaneously
Solution Approach 2:
The machine learning evaluation system is designed as a universal platform that can assess tutors across multiple subjects, languages, and evaluation criteria. The system handles diverse input formats and provides comprehensive evaluations through a single integrated platform, reducing overall system complexity by avoiding the need for separate evaluation systems for different scenarios
3Measurement precision
If comprehensive performance parameters are analyzed, then evaluation accuracy improves, but data processing time and computational resources increase
Solution Approach 1:
The system performs preliminary processing of tutor responses by pre-tokenizing text, pre-processing audio transcripts, and pre-extracting relevant features before formal evaluation. This preliminary action prepares data in advance for rapid analysis during real-time evaluation, enabling comprehensive parameter analysis without excessive processing delays
Solution Approach 2:
The evaluation system implements a two-stage analysis approach where critical parameters are analyzed in full detail while less important parameters use simplified assessment methods. This partial action strategy ensures high accuracy for key evaluation criteria while reducing overall computational burden and processing time
Data Source
AI summary
A system and a method for promoting a tutor on a platform. The system receives a tutor profile from the tutor. The tutor profile comprises a set of information about the tutor and a first cohort of students assigned to the tutor. The system randomly assigns a question received from a student belonging to a second cohort of students to the tutor in real time. The system further receives an answer to the question from the tutor. Further, the system analyses the answer based on a machine learning model. Subsequently, the system requests feedback about the tutor from the student of the second cohort of students. The system evaluates the tutor based on the plurality of parameters and the feedback receiving using deep learning algorithms. Finally, the system promotes the tutor for a group coaching of the students on the platform.
