Marginal-Likelihood Based Model Selection in Deep Learning
Scalable Marginal Likelihood Estimation for Model Selection in Deep Learning
Marginal-likelihood based model-selection, even though promising, is rarely used in deep learning due to estimation difficulties.
Instead, most approaches rely on validation data, which may not be readily available.
In this work, we present a scalable marginal-likelihood estimation method to select both the hyperparameters and network architecture based on the training data alone, and it outperforms cross-validationand manual-tuning on standard regression and image classification datasets, especially in terms of calibration and out-of-distribution detection.
