用pytorch实现三个模型来做情感分析(检测一段文字的情感是正面还是负面的),既然是情感分析任务,所以这节课依然会有很多pytorch代码,我觉得重点应该放在那三个模型上,分别是Word Averaging模型,RNN/LSTM模型和CNN模型,这三种模型或许不仅适合于情感分类任务,而且可能会迁移到别的任务上去,所以这节课既是学习pytorch得一些...
LSTM原理以及基于PyTorch的LSTM实现MNIST手写数字 循环神经网络让神经网络有了记忆, 对于序列话的数据,循环神经网络能达到更好的效果. 我们将图片数据看成一个时间上的连续数据, 每一行的像素点都是这个时刻的输入, 读完整张图片就是从上而下的读完了每行的像素点. 然后我们就可以拿出 RNN 在最后一步的分析值判断...

在自然语言的示例中,最常见的方法是使一个单词成为一个单元,并在处理该句子时将其视为一组单词。 您展开整个句子的 RNN,然后一次处理一个单词。 RNN 具有适用于不同数据集的变体,有时,选择变体时可以考虑效率。长短期记忆(LSTM)和门控循环单元(GRU)单元是最常见的 RNN 单元。
