By binarizing the indicator vector, this paper proposes an improved approximate check polytope projection algorithm (I-APPA) to improve projection efficiency. The simulation results indicate that I-APPA can red

Finally, the derived\ell_{p}regularization algorithm with adaptive regularization parameters named ADMM-SpaRe for IFI is stated in Algorithm 1 (shown in Table1). Besides, the Algorithm 1 stops when the relative maximum change of adjacent iterations becomes less than a small value\varepsilon, say\...
A first-order algorithm based on ADMM combining with proximity operator is introduced for the nonconvex model. In addition, the convergence property of the proposed algorithm is analyzed. We note that for the “nonconvex regularization +-norm fidelity” models, the authors in3,26,32also used AD...
In order to improve the tracking ability of autonomous vehicles, fuzzy control is used in combination with MPC to improve the weight of the cost function in MPC through the fuzzy adaptive algorithm. This not only improves the accuracy of trajectory tracking, but also improves the steering ...

Thus, the Nystrom sampling method is utilized to approximate the kernel matrix, which is applied in solving the kernel regression problem. To verify the effectiveness of the algorithm, we performed numerical experiments on the Spark big data platform. The experimental results show that, given ...
FedSplit is only applicable to deterministic algorithms, excluding the random approximate gradient update method commonly utilized in practice. FedPD is a primitive dual-based meta-learning algorithm, which uses the dual variable to calculate the difference between local and server learning [29]. We ...
We examined the performance of the proposed algorithm against the standard multiplicative update [38] and the ADMM [34]. We set 𝜌=1ρ=1 and the maximum iteration to be 1000. The performance results are shown in Figure 3. We can see that the proposed block method can achieve a much ...
An additional observer has been introduced to approximate the generation and load mismatch. In [13], social welfare optimization employs dual decomposition methods to achieve a distributed solution for optimal energy generation and demand. However, this algorithm does not ensure power balance. In [14...
