Time varying dimension models [PDF]
, 2010 Time varying parameter (TVP) models have enjoyed an increasing popularity in empirical macroeconomics. However, TVP models are parameter-rich and risk over-fitting unless the dimension of the model is small.

Model Reduction of LPV Control with Bounded Parameter Variation Rates [PDF]
, 2006 This paper proposes a reduced-order controller of linear parameter varying systems. The parameters are available for measurement while their ranges and rates of variation are assumed to be bounded.

Calibration for Computer Models with Time-Varying Parameter
MathematicsTraditional calibration methods often assume constant parameters that remain unchanged across input conditions, which can limit predictive accuracy when parameters actually vary.

Shrinkage in the Time-Varying Parameter Model Framework Using the R Package shrinkTVP
Journal of Statistical Software, 2021 Time-varying parameter (TVP) models are widely used in time series analysis to flexibly deal with processes which gradually change over time. However, the risk of overfitting in TVP models is well known.
