WebFeb 23, 2024 · Our approach, based on infimal convolution and cone convexity, is straightforward. The results are established under a verifiable Slater-type condition, with relaxed monotonicity and without lower semicontinuity assumptions on the functions in play. The versatility of our findings is illustrated by a series of applications in optimization … WebWe follow the avenue and propose a personalized FL method towards the three goals. When it is time to communicate, our method projects local models into a shared-and-fixed low-dimensional random subspace and uses infimal convolution to control the deviation between the reference model and projected local models. laporan keuangan adaro q3 2022

"WebMay 1, 2024 · In this paper, we propose a non-convex penalty function for sparse signal recovery by using infimal convolution approximation. First, we show that this penalty function is between the ℓ 1 norm and the difference of ℓ 1 and ℓ 2 norm (ℓ 1 − 2 norm), thus it can retain the advantages of these two norms at the same time, which means that it can … " - The infimal convolution
