Summary

TLDRThis video script introduces a machine learning project for subjective answer evaluation using natural language processing (NLP). The project aims to develop an AI system capable of automatically grading answer sheets with high accuracy. The proposed method involves training an RCN (Regional Conversion Neural Network) to understand various topics and grammatical structures, then evaluating answers based on similarity to correct responses and grammatical correctness. The project promises an accuracy of 97-98%, surpassing traditional manual grading methods, and includes a demonstration of the system in action, showcasing its ability to analyze and score answers in real-time.
