Understanding Grokking and Its Role in Automated Circuit Discovery

Leave a Comment / All Post /

Introduction to Grokking The term “grokking” originates from the science fiction novel Stranger in a Strange Land, authored by Robert A. Heinlein, where it conveys a sense of deep understanding or profound insight into a subject. To “grok” something transcends mere knowledge; it symbolizes complete and intuitive comprehension. The concept has since been adopted across

Can Weight Decay Significantly Speed Up Grokking Convergence?

Leave a Comment / All Post /

Introduction to Weight Decay and Grokking Weight decay is a regularization technique widely employed in machine learning to address the issues of overfitting. It works by adding a penalty term to the loss function that scales with the magnitude of the model’s weights. This encourages the model to maintain smaller weights while minimizing the loss,
