Unveiling the Crystal Structure of Neural Networks: A New Perspective on ReLU's Power
Analysis
This article offers a fascinating deep dive into the internal workings of ReLU networks, revealing their topology as a series of interconnected, crystal-like structures. It provides a novel way to understand how these networks process data, moving beyond the traditional view of them as smooth function approximators. The visualizations and code offer a valuable tool for researchers and enthusiasts alike.
Key Takeaways
- •ReLU networks divide input space into crystal-like polyhedra.
- •Each point in the input space gets a 'digital address' based on neuron activation.
- •The article provides code and visualizations to make complex concepts intuitive.
