Siamese Network Tensorflow Siamese network is a neural network that contain two or more identical subnetwork. The objective of this network is to find the similarity or comparing the relationship between two comparable things. Unlike classification task that uses cross entropy as the loss function, s...
2.6,Siamese Network是双胞胎连体,整一个三胞胎连体可以不? 这个问题其实已经有人做过了,叫Triplet Network,论文是《Deep metric learning using Triplet network》,输入是三个,一个正例 + 两个负例,或者一个负例 + 两个正例,训练的目的是让相同类别间的距离尽可能的小,让不同类别间的距离尽可能的大。Triplet...

Github实现地址:https://github.com/dhwajraj/deep-siamese-text-similarity 具体实现的是文章SiameseRecurrent Architectures for Learning Sentence Similarity所提出的网络结构,实现代码主要分为模型定义siamese_network.py,数据处理input_helpers.py,模型训练train.py三个部分。
实验的时候要注意,输入数据最好打乱,由于这样去设计数据集后,相同类的样本对肯定比不相同的样本对数量少,在进行训练的时候最后将两者的数据量设置成相同数量。 参考 https://github.com/ardiya/siamesenetwork-tensorflow https://www.jianshu.com/p/1df484d9eba9?utm_source=oschina-app...
plot_model(base_network,show_shapes=True,show_layer_names=True,to_file='base-model.png') 注意:对于 model subclassing 实现的模型,如果只实现了__init__()和call()方法,那么将不能进行可视化,必须再实现build_graph()方法,否则只能看到如下图: ...
只不过画两个网络仅仅只是为了阐明思想而已。同时为了后面的pseudo-siamese network做些铺垫。
