Microsoft Data Science - Navigating the hyperparameter maze

“…hyperparameter tuning has become indispensable to model optimization, influencing everything from accuracy and efficiency to scalability and generalization, helping models achieve peak performance without succumbing to issues like overfitting, underfitting, or unnecessary computational waste… we encounter a variety of techniques that serve to streamline the search for the optimal configuration…”

QwQ-32B: Embracing the Power of Reinforcement Learning

“Scaling Reinforcement Learning (RL) has the potential to enhance model performance beyond conventional pretraining and post-training methods. Recent studies have demonstrated that RL can significantly improve the reasoning capabilities of models. For instance, DeepSeek R1 has achieved state-of-the-art performance by integrating cold-start data and multi-stage training, enabling deep thinking and complex reasoning. Our research explores the scalability of Reinforcement Learning (RL) and its impact on enhancing the intelligence of large language models… QwQ-32B is open-weight in Hugging Face and ModelScope under the Apache 2.0 license and is accessible via Qwen Chat.”
