ArXiv

Analysis

This paper develops a mathematical theory to explain and predict the photonic Hall effect in honeycomb photonic crystals. It's significant because it provides a theoretical framework for understanding and potentially manipulating light propagation in these structures, which could have implications for developing new photonic devices. The use of layer potential techniques and spectral analysis suggests a rigorous mathematical approach to the problem.
Reference

“The paper proves the existence of guided electromagnetic waves at the interface of two honeycomb photonic crystals, resembling edge states in electronic systems.”

Analysis

This article by Andrej Karpathy discusses the historical significance of the 1989 Yann LeCun paper on handwritten zip code recognition, highlighting its early application of backpropagation in a real-world scenario. Karpathy emphasizes the paper's surprisingly modern structure, including dataset description, architecture, loss function, and experimental results. He then describes his efforts to reproduce the paper using PyTorch, viewing this as a case study on the evolution of deep learning. The article underscores the enduring relevance of foundational research in the field.
Reference

“The Yann LeCun et al. (1989) paper Backpropagation Applied to Handwritten Zip Code Recognition is I believe of some historical significance because it is, to my knowledge, the earliest real-world application of a neural net trained end-to-end with backpropagation.”
