Eigenvalue Corrected Noisy Natural Gradient

2018 · arXiv (Cornell University)

Variational Bayesian neural networks combine the flexibility of deep learning with Bayesian uncertainty estimation. However, inference procedures for flexible variational posteriors are computationally expensive. A recently proposed method, noisy natural gradient, is a surprisingly simple …

Functional Variational Bayesian Neural Networks

2019 · arXiv (Cornell University)

Variational Bayesian neural networks (BNNs) perform variational inference over weights, but it is difficult to specify meaningful priors and approximate posteriors in a high-dimensional weight space. We introduce functional variational Bayesian neural networks (fBNNs), which …

A Blockchain-Based Fine-Grained Reputation-Enhanced Consensus Mechanism for Secure Health Data Trading

2025 · IEEE Transactions on Computational Social Systems

With the deep integration of wearable devices and information technology, health data collection has become more efficient and accurate. This has brought about significant changes to health management and public health. However, due to the …
