Serious Data Science

Serious Data Science is an ongoing data science and machine learning collaborative learning group. This is a group of dedicated learners interested in data science and machine learning. Our focus is on learning and building skills. We are working through Building a Reasoning Model from Scratch by Sebastian Raschka and will go through Appendix C: Qwen3 LLM Source Code and Chapter 4: Improve Reasoning with Inference-Time Scaling.
