Bayesian robustness
WebBayesian neural networks are a popular type of neural network due to their ability to quantify the uncertainty in their predictive output. In contrast to other neural networks, bayesian … WebThis is especially true of Bayesian analyses. In addition to the usual concerns about the agreement of the data and model, a Bayesian must contemplate the effect of an uncertain prior specification. The degree to which inferences are robust to changes in the prior is of primary interest.
