• Abstract: In this paper, we use certain norm inequalities to obtain new uncertain relations based on the Wigner-Yanase skew information. First for an arbitrary finite number of observables we derive an uncertainty relation outperforming previous lower bounds. We then propose new weighted uncertainty relations for two noncompatible observables. Two separable criteria via skew information are also obtained.

• Uncertainty relations based on state-dependent norm of commutator [0.0]
  We introduce two uncertainty relations based on the state-dependent norm of commutators, utilizing generalizations of the B"ottcher-Wenzel inequality. The first relation is mathematically proven, while the second, tighter relation is strongly supported by numerical evidence.

  Wigner-Yanase skew information stands for the uncertainty about the information on the values of observables not commuting with the conserved quantity. We present tight uncertainty relations in both product and summation forms for two quantum channels based on the Wigner-Yanase skew information.

• Open Set Relation Extraction via Unknown-Aware Training [72.10462476890784]
  We propose an unknown-aware training method, regularizing the model by dynamically synthesizing negative instances. Inspired by text adversarial attacks, we adaptively apply small but critical perturbations to original training instances. Experimental results show that this method achieves SOTA unknown relation detection without compromising the classification of known relations.

• Monotonicity and Double Descent in Uncertainty Estimation with Gaussian Processes [52.92110730286403]
  It is commonly believed that the marginal likelihood should be reminiscent of cross-validation metrics and that both should deteriorate with larger input dimensions. We prove that by tuning hyper parameters, the performance, as measured by the marginal likelihood, improves monotonically with the input dimension. We also prove that cross-validation metrics exhibit qualitatively different behavior that is characteristic of double descent.

• Dense Uncertainty Estimation via an Ensemble-based Conditional Latent Variable Model [68.34559610536614]
  We argue that the aleatoric uncertainty is an inherent attribute of the data and can only be correctly estimated with an unbiased oracle model. We propose a new sampling and selection strategy at train time to approximate the oracle model for aleatoric uncertainty estimation. Our results show that our solution achieves both accurate deterministic results and reliable uncertainty estimation.
