Overview
- Research develops a learned version of Bayesian Cramér-Rao bound (BCRB)
- Introduces two approaches: Posterior and Measurement-Prior
- Uses physics-encoded neural networks to incorporate domain knowledge
- Tests methods on signal processing problems including frequency estimation
- Validates approach with real-world underwater ambient noise data
Plain English Explanation
Signal processing experts need ways to measure how accurate their estimates can be. The Bayesian Cramér-Rao bound (BCRB) is like a measuring stick for this purpose, but it requires knowing exact probability distributions beforehand.
This research creates a [learned Bayesian fr...
