A teaching assistant that answers from the lecture notes
TalkerAn open source teaching assistant, built as a USC master's capstone, that drafts answers to course-forum questions from the lecture notes, with hybrid retrieval, a reranker, and an evaluation harness that scores its own retrieval.
AI/ML · Open Source
Highlights
- Hybrid BM25 + vector retrieval, so exact course terms and paraphrased questions both find their passage
- Six model providers behind one interface — OpenAI, Anthropic, Gemini, Cohere, Ollama and HuggingFace — with Ollama for a fully local setup, and token cost tracked per provider
- A RAGAS-style LLM-as-judge harness that scores retrieval and answer quality instead of eyeballing it
