Hyperparameters fine tuning for MARL comparative study [D]
Evaluating multi-agent reinforcement learning (MARL) architectures demands rigorous methodology. A common challenge arises when optimal hyperparameters—learning rates, entropy coefficients, and batch sizes—vary across different model configurations. While unifying hyperparameters can appear advantageous for fair comparison, it risks hindering convergence. This study investigates the robustness of PPO variants (Independent PPO, Graph PPO, etc.) under adversarial attack, necessitating careful consideration of hyperparameter tuning. See "Continual Learning of Frontier Models" for related insights into model development.
Backpropagation Explained for Beginners (Part 3): How Backpropagation Really Works
## Backpropagation Explained for Beginners (Part 3): How Backpropagation Really Works Ready to understand the core of neural network training? This post dives into how backpropagation truly functions, moving beyond the initial concept to explore the cascade of gradients. We'll break down the process of calculating gradients from a single point to every parameter, illuminating how this iterative refinement shapes model learning. For a deeper dive into the broader context of data intelligence and decision-making, see "Before Full Agentic RAG.
Don’t Just “Throw Adam at It”: Misunderstanding Adam Will Cost You
Misunderstanding Adam—our AI-powered data optimizer—can lead to frustrating and costly failures. Don't simply "throw Adam at it"; a shallow approach will likely yield suboptimal results. This post dives deep into Adam's optimization dynamics, explaining precisely *why* it sometimes fails spectacularly and, crucially, how to rectify those issues. We’ll equip you with the knowledge to harness Adam’s full potential and avoid common pitfalls in your data workflows. For broader context on AI agent workflows, see "GM redesigned its engineering workflows around AI agents."
Backpropagation Explained for Beginners (Part 2): There Has to Be a Better Way
Understanding backpropagation is crucial for grasping how neural networks learn, but the underlying concept can feel abstract. This post, "Backpropagation Explained for Beginners (Part 2): There Has to Be a Better Way," clarifies the pivotal idea that makes backpropagation possible – a foundational element for AI advancement. We explore this concept with clarity, building on introductory knowledge.
The qlora 2e-4 default is wrong under 10k samples and nobody talks about it [D]
Fine-tuning QLoRA models on smaller datasets—less than 10,000 samples—often leads to unexpected results. The pervasive default learning rate of 2e-4, widely promoted across tutorials and documentation, can actually trigger overfitting. Extensive experimentation reveals that a starting learning rate of 1e-4 or lower, combined with increased epochs, consistently yields significantly improved evaluation metrics. This adjustment, easily implemented, can save practitioners considerable time and frustration, as detailed in a recent discussion about ECCV expenses.
