highly folded data manifolds. At this point, you should have a pretty good intuition as to why deep learning excels this: it takes the approach of incrementally decomposing a complicated geometric transformation into a long chain of elementary ones, which is pretty much a strategy...
and comes out in a more useful form. Precisely, layers extract _representations_ out of the data fed into them -- hopefully representations that are more meaningful for the problem at hand. Most of deep learning really
Learn Deep Learning with Python 3 app introduces the field of deep learning using Python and the powerful Keras library. As you move through this app, you’ll bu…
卷积神经网络学到的模式具有平移不变性(translation invariant)卷积神经网络在图像右下角学到某个模式之后,它可以在任何地方识别这个模式,比如左上角 对于密集连接网络来说,如果模式出现在新的位置,它只能重新学习这个模式 卷积神经网络可以学到模式的空间层次结构(spatial hierarchies of patterns)第一个卷积层将学习较小...
本文中,学习(learning)意味着寻找神经网络中所有layer的权重值的集合,比如正确地将样本数据集的输入和相关的目标映射。这里需要注意的是,一个神经网络可能包含成千上万个参数。修改某个参数可能会影响其它所有的参数,那找到所有参数的正确值看似是个相当艰巨的任务。
