The proposed neural-g estimator uses a softmax output layer to ensure the estimated prior is a valid probability density. This new approach shows promise in capturing complex prior shapes, including those with flat regions, heavy tails, and/or discontinuities. The authors demonstrate the flexibility of neural-g through simulations and real-world dataset analyses, outperforming existing methods. A software package for implementing neural-g is publicly available.
Low GrooveSquid.com (original content) Low Difficulty Summary
Neural-g is a new way to estimate probability densities using neural networks. It helps make good predictions by accurately estimating how likely something is to happen. This method can learn many different shapes of prior probabilities, including flat regions and heavy tails. The authors tested this approach on simulated data and real-world datasets and found it works well. They even created a software package for others to use.
