Learning to (learn at test time): Rnns with expressive hidden states

Y Sun, X Li, K Dalal, J Xu, A Vikram, G Zhang… - arXiv preprint arXiv …, 2024 - arxiv.org
Self-attention performs well in long context but has quadratic complexity. Existing RNN
layers have linear complexity, but their performance in long context is limited by the …

Nonparametric estimation of conditional VaR and expected shortfall

Z Cai, X Wang - Journal of Econometrics, 2008 - Elsevier
This paper considers a new nonparametric estimation of conditional value-at-risk and
expected shortfall functions. Conditional value-at-risk is estimated by inverting the weighted …

Random grid neural processes for parametric partial differential equations

A Vadeboncoeur, I Kazlauskaite… - International …, 2023 - proceedings.mlr.press
We introduce a new class of spatially stochastic physics and data informed deep latent
models for parametric partial differential equations (PDEs) which operate through scalable …

Learning to (learn at test time)

Y Sun, X Li, K Dalal, C Hsu, S Koyejo… - arXiv preprint arXiv …, 2023 - arxiv.org
We reformulate the problem of supervised learning as learning to learn with two nested
loops (ie learning problems). The inner loop learns on each individual instance with self …

Data-driven transient stability assessment based on kernel regression and distance metric learning

X Liu, Y Min, L Chen, X Zhang… - Journal of Modern Power …, 2020 - ieeexplore.ieee.org
Transient stability assessment (TSA) is of great importance in power systems. For a given
contingency, one of the most widely-used transient stability indices is the critical clearing …

On conditional density estimation

JG De Gooijer, D Zerom - Statistica Neerlandica, 2003 - Wiley Online Library
With the aim of mitigating the possible problem of negativity in the estimation of the
conditional density function, we introduce a so‐called re‐weighted Nadaraya‐Watson …

Particle-swarm-optimization-enhanced radial-basis-function-kernel-based adaptive filtering applied to maritime data

N Lopac, I Jurdana, J Lerga… - Journal of marine science …, 2021 - mdpi.com
The real-life signals captured by different measurement systems (such as modern maritime
transport characterized by challenging and varying operating conditions) are often subject to …

Selection of smoothing parameter estimators for general regression neural networks–applications to hydrological and water resources modelling

X Li, AC Zecchin, HR Maier - Environmental modelling & software, 2014 - Elsevier
Multi-layer perceptron artificial neural networks are used extensively in hydrological and
water resources modelling. However, a significant limitation with their application is that it is …
