TITLE of the website: Evolver AI - Business Lab - KAN Explorer Frontend Requirements: 1. Create an intuitive user interface for configuring the parameters of Kolmogorov-Arnold Networks (KAN) and its dynamic weight integration. • Include all input parameters such as the number of inner/outer units, grid points, spline degrees, learning rate, and other relevant hyperparameters. • Allow users to adjust these parameters via sliders, dropdowns, or input fields. • OBLIGATORY: Provide a real-time reduce-size visualization of the network behavior as parameters are modified. 2. Result Visualizations: • Display metrics such as AUC, KS Statistic, and Log Loss after the experiments. • Generate a chart of the loss function over training epochs (X-axis = epochs, Y-axis = loss). 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: • Use the provided PyTorch code to compute metrics (AUC, KS Statistic, Log Loss) based on user-configured parameters. • Log and output the training loss at each epoch for visualization in the frontend. 3. Ensure the backend is capable of processing user-configured input parameters and reflecting them in the experiment results. (Code provided below should be integrated into the backend implementation.)

parameters of the Attention-KAN approach detailed in this article: Kolmogorov-Arnold Networks: Exploring Dynamic Weights and Attention Mechanisms. TITLE of the website: Evolver AI - Business Lab - KAN Explorer Frontend Requirements: 1. Create an intuitive user interface for configuring the parameters of Kolmogorov-Arnold Networks (KAN) and its dynamic weight integration. • Include all input parameters such as the number of inner/outer units, grid points, spline degrees, learning rate, and other relevant hyperparameters. • Allow users to adjust these parameters via sliders, dropdowns, or input fields. • OBLIGATORY: Provide a real-time reduce-size visualization of the network behavior as parameters are modified. 2. Result Visualizations: • Display metrics such as AUC, KS Statistic, and Log Loss after the experiments. • Generate a chart of the loss function over training epochs (X-axis = epochs, Y-axis = loss). 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: • Use the provided PyTorch code to compute metrics (AUC, KS Statistic, Log Loss) based on user-configured parameters. • Log and output the training loss at each epoch for visualization in the frontend. 3. Ensure the backend is capable of processing user-configured input parameters and reflecting them in the experiment results. (Code provided below should be integrated into the backend implementation.) Below are the code snippet for Backend Implementation of 2 examples ### Code for Example 1: of Dynamic KAN Experiment ==================================================== import torch import torch.nn as nn import torch.optim as optim from sklearn.metrics import roc_auc_score, log_loss, roc_curve from sklearn.model_selection import train_test_split # Dynamic Weight Generator class DynamicWeightGenerator(nn.Module): def __init__(self, input_dim, output_dim): super(DynamicWeightGenerator, self).__init__() self.fc1 = nn.Linear(input_dim, 128) self.fc2 = nn.Linear(128, 64) self.fc_weight = nn.Linear(64, output_dim) self.fc_bias = nn.Linear(64, output_dim) self.softplus = nn.Softplus() def forward(self, x): h = torch.relu(self.fc1(x)) h = torch.relu(self.fc2(h)) weight = self.softplus(self.fc_weight(h)) bias = self.fc_bias(h) return weight, bias # Kolmogorov-Arnold Network (KAN) class KAN(nn.Module): def __init__(self, input_dim, num_inner_units, num_outer_units, dynamic=True): super(KAN, self).__init__() self.dynamic = dynamic self.num_inner_units = num_inner_units self.num_outer_units = num_outer_units if dynamic: self.inner_weight_generators = nn.ModuleList([ DynamicWeightGenerator(input_dim, input_dim) for _ in range(num_inner_units) ]) self.outer_weight_generators = nn.ModuleList([ DynamicWeightGenerator(input_dim, 1) for _ in range(num_outer_units) ]) else: self.inner_weights = nn.ParameterList([ nn.Parameter(torch.randn(input_dim, input_dim)) for _ in range(num_inner_units) ]) self.inner_biases = nn.ParameterList([ nn.Parameter(torch.randn(input_dim)) for _ in range(num_inner_units) ]) self.outer_weights = nn.ParameterList([ nn.Parameter(torch.randn(num_inner_units)) for _ in range(num_outer_units) ]) self.outer_biases = nn.ParameterList([ nn.Parameter(torch.randn(1)) for _ in range(num_outer_units) ]) def forward(self, x): inner_outputs = [] if self.dynamic: for generator in self.inner_weight_generators: weight, bias = generator(x) inner_output = torch.sum(weight * x + bias, dim=-1, keepdim=True) inner_outputs.append(inner_output) else: for weight, bias in zip(self.inner_weights, self.inner_biases): inner_output = torch.sum(torch.matmul(x, weight) + bias, dim=-1, keepdim=True) inner_outputs.append(inner_output) aggregated_inner_output = torch.cat(inner_outputs, dim=-1) outer_outputs = [] if self.dynamic: for generator in self.outer_weight_generators: weight, bias = generator(x) outer_output = torch.sum(weight * aggregated_inner_output + bias, dim=-1, keepdim=True) outer_outputs.append(outer_output) else: for weight, bias in zip(self.outer_weights, self.outer_biases): outer_output = torch.sum(aggregated_inner_output * weight + bias, dim=-1, keepdim=True) outer_outputs.append(outer_output) final_output = torch.sum(torch.cat(outer_outputs, dim=-1), dim=-1, keepdim=True) return final_output # Data generation torch.manual_seed(42) num_samples = 1200 input_dim = 5 # Generate complex non-linear data X = torch.rand((num_samples, input_dim)) * 10 -
