Relative Flatness and Generalization

Neural Information Processing Systems

Flatness of the loss curve is conjectured to be connected to the generalization ability of machine learning models, in particular neural networks.



Flow Matching for Scalable Simulation-Based Inference

Neural Information Processing Systems

Figure 1: Comparison of network architectures (left) and flow trajectories (right). Discrete flows (NPE, top) require a specialized architecture for the density estimator. Continuous flows (FMPE, bottom) are based on a vector field parametrized with an unconstrained architecture.

On Locality of Local Explanation Models

Neural Information Processing Systems

The use of a global population can lead to potentially misleading results when local model behaviour is of interest. Hence we consider the formulation of neighbourhood reference distributions that improve the local interpretability of Shapley values.


A EM-algorithm to fit LDF A-H (Section 2) Initialization Let null ฮธ

Neural Information Processing Systems

Since the MPLE objective function for LDFA-H given in Eq. (9) is not guaranteed convex, an EM-algorithm may find a local minimum according to a choice of the initial value. Hence a good initialization is crucial to a successful estimation. According to the equivalence between CCA and probablistic CCA shown by A. Anonymous, it gives (r 1) (r 1) (r 1) (r 1) Lasso problem is solved by the P-GLASSO algorithm by Mazumder et al. (2010). We simulated realistic data with known cross-region connectivity as follows. Notice that the amplitudes of the top four factors dominate the others.



Understanding the Under-Coverage Bias in Uncertainty Estimation

Neural Information Processing Systems

Estimating the data uncertainty in regression tasks is often done by learning a quantile function or a prediction interval of the true label conditioned on the input.
