> Summary of the constrained recursive least squares (CRLS) subspace algorithm (1) Use the CLS subspace algorithm in Section 2 to initialize the parameter vector θ ˆ N f and covariance P ˆ N from a set {u 0, y 0, ⋯ , u N−1, y N−1} of N input–output data. Often the least squares solution is also required to satisfy a set of linear constraints, which again can be divided into sparse and dense subsets. In this paper, we propose an improved recursive total least squares … (2015) A constrained recursive least squares algorithm for adaptive combination of multiple models. The constrained ... also includes time‐varying parameters that are not constrained by a dynamic model. As such at each time step, a closed solution of the model combination parameters is available.

A distributed recursive … Moreover an l1-norm constraint to the combination parameters is also applied with the aim to achieve sparsity of multiple models so that only a subset of models may be selected into the final model.
