UnverifiedGradient-based attribution methods use the gradient of the neural network output with respect to the input features (∂output/∂input) to measure the contribution of each input dimension to the decision.71% similarUnverifiedExperimental results show that directly using the network's final classification layer as the calibrator yields a model that is both accurate and well-calibrated without introducing additional parameters.69% similarUnverifiedThe core idea of trainable activation functions is to include certain parameters inside the activation function in the gradient descent optimization process, allowing the network to automatically adjust the shape of the activation function based on data.67% similarUnverifiedAnyInit's approach is to automatically estimate the per-layer variance ratio for any layer through numerical or structural analysis and infer the initialization parameters in reverse, thereby bypassing dependence on closed-form formulas.66% similarUnverifiedThe decision head is an additional output layer outside the model backbone, typically receiving the feature vector extracted by the backbone and outputting a judgment result or score.66% similar
