TensorFlow lbfgs参数如何调 tensorflow lstm LSTM,全称为长短期记忆网络(Long Short Term Memory networks),是一种特殊的RNN,能够学习到长期依赖关系。LSTM由Hochreiter & Schmidhuber (1997)提出,许多研究者进行了一系列的工作对其改进并使之发扬光大。 LSTM在解决许多问题上效果非常好,现在被广泛使用。它们主要用于处...

几天遇到了一个巨坑!!! 按照网上说的方法,在RTX3090上装了tensorflow-gpu 1.15.4/1.15.5, 结果只能迭代几次就停了,应该是tensorflow和scipy的接口那里迭代停止条件没有传过来。 最后找了个RTX 2080 的服务器装了 tensorflow-gpu 1.15.0, 才正常运行。。
tf.train.L_BFGS_Optimizer#446 This would be a great addition to tensorflow, and is conspicuously missing. Is there some specific reason it's missing, or is it in the works? 👍11 martinwicke commentedon Dec 26, 2015 martinwicke
The L-BFGS-B algorithm allows to optimize functions with box-constraints, i.e., min_x f(x) s.t. a <= x <= b for some a, b. Given a BoundedProblem-class you can enter these constraints by // init problem YourBoundedProblem f; f.setLowerBound(Vector<double>::Zero(DIM)); f....
(6)newton-cg', 'lbfgs' and 'sag' 只能处理 L2 penalty, 'liblinear' and 'saga' 能处理 L1 penalty。 10.max_iter: 指定最大迭代次数。default: 100。只对'newton-cg', 'sag' and 'lbfgs'适用。 11.multi_class:{'ovr', 'multinomial'}, default: 'ovr'。指定对分类问题的策略。 (1)multi_...
