The evolution-based algorithm uses an iterative procedure to evolve the population from one generation to the next. These algorithms are inspired by the natural evolution of species that tries to reach a better state in successive generations [49]. These algorithms start with random initialization ...
The FTRL-Proximal algorithm uses the updateWt+1=argwmin(g1:t.w+1/2∑ts=1σs||w−ws||22+λ1||w||1)Wt+1=argwmin(g1:t.w+1/2∑s=1tσs||w−ws||22+λ1||w||1),σ1:t=1/ηtσ1:t=1/ηt when we takeλ1=0λ1=0, they produce an identical sequence of coefficien...

of combinatorial optimization problems that admit an FPTAS (fully polynomial time approximation scheme), in which T is the number of rounds of the learning process. In addition to the theoretical analysis, we also conduct a series of experiments to demonstrate the perfor...
FTRLp.py LICENSE.md README.md --- Follow The Regularized Leader - Proximal --- FTRL-P is an online classification algorithm that combines both L1 and L2 regularization and feature based, adaptive learning rates, particularly suited for large data sets with extremely high dimensionality and multi...
The waypoints are then refined using a Follow Shape Rapidly-exploring Random Tree algorithm (FSRRT) for cases that the initial configurations of the CTR cannot completely satisfy the FTL deployment. Simulations and experiments are carried out on a human brain model to validate the proposed methods....
