Exploring Llama 3.2 3B’s Hidden Dimensions
Read Full Article: Exploring Llama 3.2 3B’s Hidden Dimensions
A local interpretability tool has been developed to visualize and intervene in the hidden-state activity of the Llama 3.2 3B model during inference, revealing a persistent hidden dimension (dim 3039) that influences the model's commitment to its generative trajectory. Systematic tests across various prompt types and intervention conditions showed that increasing intervention magnitude led to more confident responses, though not necessarily more accurate ones. This dimension acts as a global commitment gain, affecting how strongly the model adheres to its chosen path without altering which path is selected. The findings suggest that magnitude of intervention is more impactful than direction, with significant implications for understanding model behavior and improving interpretability. This matters because it sheds light on how AI models make decisions and the factors influencing their confidence, which is crucial for developing more reliable AI systems.

MIT: AIs Rediscovering Physics Independently
Read Full Article: MIT: AIs Rediscovering Physics Independently
Recent research from MIT reveals that independent scientific AIs are not merely simulating known physics but are also rediscovering fundamental physical laws on their own. These AI systems have demonstrated the ability to independently derive principles similar to Newton's laws of motion and other established scientific theories without prior programming of these concepts. This breakthrough suggests that AI could play a significant role in advancing scientific discovery by offering new insights and validating existing theories. Understanding AI's potential to autonomously uncover scientific truths could revolutionize research methodologies and accelerate innovation.
