+Website generated by Claude from prompt: Including the code in your prompt is a good idea if you want the developers or team working on the project to implement these specific examples in the backend. By providing the exact implementation, you ensure alignment with the article’s experiments and reduce ambiguity. Here’s how you can integrate it effectively: Improved Prompt with Code Integration: Objective: Develop a website that allows users to configure and experiment with parameters of the Attention-KAN approach detailed in this article: Kolmogorov-Arnold Networks: Exploring Dynamic Weights and Attention Mechanisms. Frontend Requirements: 1. Create an intuitive user interface for configuring the parameters of Kolmogorov-Arnold Networks (KAN) and its dynamic weight integration. • Allow users to adjust parameters like the number of inner/outer units, grid points, and spline degrees. • Provide real-time visualizations of the network behavior as parameters are modified. 2. Display metrics (AUC, KS Statistic, Log Loss) after experiments for better user comprehension. Backend Requirements: 1. Implement the following example experiments provided in the article: • Example 1: Training and evaluation of a Dynamic Weight KAN. • Example 2: Training and evaluation of an Improved Standard KAN using spline-based utilities. 2. The backend should run the provided PyTorch code to compute metrics (e.g., AUC, KS Statistic, Log Loss) for user-configured parameters. (Code provided below should be integrated into the backend implementation.)
