Read Full Article: Stabilizing Hyper Connections in AI Models
DeepSeek researchers have addressed instability issues in large language model training by applying a 1967 matrix normalization algorithm to hyper connections. Hyper connections, which enhance the expressivity of models by widening the residual stream, were found to cause instability at scale due to excessive amplification of signals. The new method, Manifold Constrained Hyper Connections (mHC), projects residual mixing matrices onto the manifold of doubly stochastic matrices using the Sinkhorn-Knopp algorithm, ensuring numerical stability by maintaining controlled signal propagation. This approach significantly reduces amplification in the model, leading to improved performance and stability with only a modest increase in training time, demonstrating a new axis for scaling large language models. This matters because it offers a practical solution to enhance the stability and performance of large AI models, paving the way for more efficient and reliable AI systems.

Adapting Agentic AI: New Framework from Stanford & Harvard
Read Full Article: Adapting Agentic AI: New Framework from Stanford & Harvard
Agentic AI systems, which build upon large language models by integrating tools, memory, and external environments, are currently used in various fields such as scientific discovery and software development. However, they face challenges like unreliable tool use and poor long-term planning. Research from Stanford, Harvard, and other institutions proposes a unified framework for adapting these systems, focusing on a foundation model agent with components for planning, tool use, and memory. This model adapts through techniques like supervised fine-tuning and reinforcement learning, aiming to enhance the AI's ability to plan and utilize tools effectively. The framework defines four adaptation paradigms based on two dimensions: whether adaptation targets the agent or tools, and whether the supervision signal comes from tool execution or final agent outputs. A1 and A2 paradigms focus on agent adaptation, with A1 using feedback from tool execution and A2 relying on final output signals. T1 and T2 paradigms concentrate on tool adaptation, with T1 optimizing tools independently of the agent and T2 adapting tools under a fixed agent. This structured approach helps in understanding and improving the interaction between agents and tools, ensuring more reliable AI performance. Key takeaways include the importance of combining different adaptation methods for robust and scalable AI systems. A1 methods like Toolformer and DeepRetrieval adapt agents using verifiable tool feedback, while A2 methods optimize agents based on final output accuracy. T1 and T2 paradigms focus on training tools and memory, with T1 developing broadly useful retrievers and T2 adapting tools under a fixed agent. The research suggests that practical systems will benefit from rare agent updates combined with frequent tool adaptations, enhancing both robustness and scalability. This matters because improving the reliability and adaptability of agentic AI systems can significantly enhance their real-world applications and effectiveness.
