local optimum

基本解釋

The results show the optimized BP neural network can effectively avoid converging on local optimum and reduce training time greatly.
實(shí)驗(yàn)結(jié)果證明，優(yōu)化后的BP網(wǎng)絡(luò)可有效地避免收斂于局部最優(yōu)值，大大地縮短了訓(xùn)練時(shí)間。
The registration results showed that the subvoxel accuracy could be achieved and this method can avoid getting into the local optimum.
實(shí)驗(yàn)表明，該算法能避免陷入局部最優(yōu)值，配準(zhǔn)結(jié)果精度達(dá)到亞像素級(jí)。
The adoption of remembrance-guided search method emphasizes local optimum value in each remembrance segment, which avoids the blindness of global search.
算法中采用的記憶指導(dǎo)搜索策略重點(diǎn)搜索了各記憶段的局部最優(yōu)值，避免了全局搜索的盲目性；

局部最優(yōu)
The constriction factor Particle Swarm Optimization(PSO) algorithm is easily trapped in the local optimum and appeared premature convergence.
收縮因子粒子群優(yōu)化算法容易陷入局部最優(yōu)并出現(xiàn)早熟收斂的現(xiàn)象。
局部極值
K-means algorithm is simple and fast,however its result is affected by the initial clustering center and easily falls into the local optimum.
K均值算法簡單快速,但其結(jié)果容易受初始聚類中心影響,并且容易陷入局部極值。
