What is TheoremExplainAgent?
TheoremExplainAgent (TEA) is an open source multimodal agent system from institutions such as the University of Waterloo and Votee Al. It helps people better understand mathematical and scientific theorems by generating long animated videos. TheoremExplainAgent supports the generation of educational videos longer than 5 minutes, covering multiple STEM fields (such as mathematics, physics, chemistry, and computer science). To evaluate performance, researchers launched the TheoremExplainBench (TEB) benchmark dataset, which contains 240 theorems and evaluates them from multiple dimensions such as accuracy, depth, logical flow, visual relevance, and element layout. Experiments show that TheoremExplainAgent performs well in the success rate of generating long videos, can reveal deep-level reasoning errors that are easily missed in text explanations, and provides new ideas for AI to generate educational content.
The main functions of TheoremExplainAgent
Generate long videos: Generate explanation videos of more than 5 minutes based on the input theorem, covering multiple disciplines such as mathematics, physics, chemistry and computer science.
Multimodal explanation: Combine text, animation and voice to enhance the understanding of abstract concepts in a visual way.
Automatic error diagnosis: Expose reasoning errors in the form of videos to help developers diagnose the logical loopholes of the model more clearly.
Interdisciplinary versatility: Supports theorems of different difficulty levels (from high school to graduate level) and is applicable to a variety of STEM fields.
Systematic evaluation: Based on the TheoremExplainBench benchmark and multi-dimensional evaluation indicators, the quality and accuracy of the generated videos are systematically measured.
Technical principles of TheoremExplainAgent
Planning agent: Responsible for generating the overall plan of the video based on the input theorem, including scene division, goals of each scene, content description and visual layout.
Using techniques such as Chain-of-Thought and Program-of-Thought, we ensure the logical coherence and depth of the video content.
Coding agent: Based on the detailed plan generated by the planning agent, we use Manim (a Python library for creating mathematical animations) to generate animation scripts. Based on the retrieval-augmented generation (RAG) technology, we use Manim documents as a knowledge base to dynamically retrieve code snippets and API documents to improve the accuracy and efficiency of code generation. During the code generation process, we automatically detect and fix errors to ensure that the video is correctly rendered.
Multimodal fusion: The video content combines text narration, animation demonstration, and voice explanation to enhance the understanding of theorems in a visual way. We use image processing technology and natural language processing models (such as GPT-4o and Gemini 2.0 flash) to evaluate the generated videos in multiple dimensions to ensure the accuracy and visual quality of the content.
Systematic evaluation: The TheoremExplainBench benchmark is introduced, which contains 240 theorems covering multiple disciplines and difficulty levels. Introduced five automatic evaluation indicators (accuracy, visual relevance, logical flow, element layout and visual consistency) to comprehensively measure the quality of A1 generated videos
