[解释] The dimension of word vectors is usually smaller than the size of the vocabulary. Most common sizes for word vectors ranges between 50 and 400. [解释] 过用t-SNE算法来将单词可视化.t-SNE算法所做的就是把这些n维的数据用一种非线性的方式映射到2维平面上,可以得知t-SNE中这种映射很复杂而且很非线性. [解释] Yes, word v…
第一周 循环序列模型(Recurrent Neural Networks) 为什么选择序列模型?(Why Sequence Models?) 在本课程中你将学会序列模型,它是深度学习中最令人激动的内容之一.循环神经网络(RNN)之类的模型在语音识别.自然语言处理和其他领域中引起变革.在本节课中,你将学会如何自行创建这些模型.我们先看一些例子,这些例子都有效使用了序列模型. 在进行语音识别时,给定了一个输入音频片段 \(X\),并要求输出对应的文字记录 \(Y\).这个例子里输入和输出数据都是序列…
由于本章过长,分为两个部分,这是第一部分. 这几年提到RNN,一般指Recurrent Neural Networks,至于翻译成循环神经网络还是递归神经网络都可以.wiki上面把Recurrent Neural Networks叫做时间递归神经网络,与之对应的还有一个结构递归神经网络(recursive neural network).本文讨论的是前者. RNN是一种可以预测未来(在某种程度上)的神经网络,可以用来分析时间序列数据(比如分析股价,预测买入点和卖出点).在自动驾驶中,可以预测路线…
