这也是加快梯度运算的算法之一。 6.8 Adam优化算法(Adam optimization algorithm) 该算法是Momentum算法和RMSprop算法的结合,如下图所示: 关于一些参数的选择参考下图: 6.9 学习率衰减(Learning rate decay) 慢慢减少α的本质在于,在学习初期,你能承受较大的步伐,但当开始收敛的时候,小一些的学习率能让你步伐小一些。
蜂群优化算法(bee colony optimization algorithm) 注意:本文引用自专业人工智能社区Venus AI 更多AI知识请参考原站 ([www.aideeplearning.cn]) 算法引言 自然界的启发:BSO算法的灵感来自于蜜蜂在自然界中的觅食行为。在自然界中,蜜蜂需要找到花蜜来生存。当一只蜜蜂找到一片花丛时,它会返回蜂巢,通过特殊的“摆动...
Search and optimization algorithms are powerful tools that can help practitioners find optimal or near-optimal solutions to a wide range of design, planning and control problems. When you open a route planning app, call for a rideshare, or schedule a hospital appointment, an AI algorithm works ...
