Optimal margin distribution clustering
WebJul 1, 2024 · Although the optimal margin distribution machine (ODM) has better generalization performance in pattern recognition than traditional classifiers, ODM as well as traditional classifiers often suffers from data imbalance. To address this, this paper proposes a kernel modified ODM (KMODM) to eliminate the side effect of imbalanced data. WebFeb 23, 2024 · In this paper, a method for rationally allocating energy storage capacity in a high-permeability distribution network is proposed. By constructing a bi-level programming model, the optimal capacity of energy storage connected to the distribution network is allocated by considering the operating cost, load fluctuation, and battery charging and …
