即使你之前了解过逻辑回归,我认为这里还是有些新的、有趣的东西等着你去发现和了解,所以现在开始进入正题 逻辑回归是一个用于二分类($binary\ classification$)的算法。

昨天的周日讨论班讲的是TreeLSTM Sentiment Classification,主讲人:王铭涛 今天我来做一下总结。 下面的图片来自于 王铭涛的ppt 导读 我们一步一步来。
具体示例 说了上面这么多,恐怕很多人还是云里雾里的,我就结合一个具体的示例来说说如何进行image 的classification 假设: 1. 你已经把你的数据训练好了 2....保留了你的网络结构 现在就是来了一堆新图,在某个目录下,你要做的就是进行这些图像的classification,如何做??? 示例: # -*- coding: utf-8 -*- #!...sys.path.insert(0, caffe_root + 'python') # 包含测试image的文件夹 test_dir='/path/to/your/recognition/directory' # classification...caffe_root + sysTXTPath labels = np.loadtxt(imagenet_labels_filename, str, delimiter= ':') # 循环迭代进行每个图片的classification

我们初步的设想是,首先将一个句子输入到LSTM,这个句子有多少个单词,就有多少个输出,然后将所有输出通过一个Linear Layer,这个Linear Layer的out_size是1,起到Binary Classification

这几天看了几篇相关的文章, 写篇文章总结一下,就像个小综述一样, 文章会很乱 1、multilabel classification的用途 多标签分类问题很常见, 比如一部电影可以同时被分为动作片和犯罪片
