It is a common occurrence in practice the need for scalar encoding schemes that can recover from quantizer errors, that also have fast rates of convergence. Recently, DeVore et al. introduced the beta-encoding scheme, that has this type of robustness under certain general conditions. In this talk we will explore this scheme's properties, as well as some modifications to the same that have been obtain on the last few years. In particular: Golden ratio encoders, beta-alpha encoders and sign-beta encoders.
