Distributed Universal Adaptive Networks
Cassio G. Lopes, Vítor H. Nascimento, Luiz F. O. Chamon
Adaptive networks (ANs) are effective real time techniques to process and track events observed by sensor networks and, more recently, to equip Internet of Things (IoT) application…
Nonlinear Adaptive Algorithms on Rank-One Tensor Models
Felipe C. Pinheiro, Cassio G. Lopes
This work proposes a low complexity nonlinearity model and develops adaptive algorithms over it. The model is based on the decomposable---or rank-one, in tensor language---Volterra…
Geometric-Algebra Adaptive Filters
Wilder B. Lopes, Cassio G. Lopes
This paper presents a new class of adaptive filters, namely Geometric-Algebra Adaptive Filters (GAAFs). They are generated by formulating the underlying minimization problem (a det…
Combination of LMS Adaptive Filters with Coefficients Feedback
Luiz F. O. Chamon, Cassio G. Lopes
Parallel combinations of adaptive filters have been effectively used to improve the performance of adaptive algorithms and address well-known trade-offs, such as convergence rate v…
A Nonlinear Adaptive Filter Based on the Model of Simple Multilinear Functionals
Felipe C. Pinheiro, Cássio G. Lopes
Nonlinear adaptive filtering allows for modeling of some additional aspects of a general system and usually relies on highly complex algorithms, such as those based on the Volterra…
Geometric-Algebra LMS Adaptive Filter and its Application to Rotation Estimation
Wilder B. Lopes, Anas Al-Nuaimi, Cassio G. Lopes
This paper exploits Geometric (Clifford) Algebra (GA) theory in order to devise and introduce a new adaptive filtering strategy. From a least-squares cost function, the gradient is…
