有两种主要的神经网络结构,即前馈网络( feed-forward network)和循环/递归网络(recurrent/ recursive network),它们可以以各种方式组合。 循环神经网络 (RNN)是适于序列数据的特殊模型,循环网络很少被当作独立组件应用,其能力在于可被当作可训练的组件“喂”给其他网络组件,然后串联地训练它们。例如,循环网络的输出可以“...
hinge loss 在我们想要一个hard decision rule(Soft classifiers explicitly estimate the class conditional probabilities and then perform classification based on estimated probabilities. In contrast, hard classifiers directly target the classification decision boundary without producing the probability estimation ---...

Transformer neural networks are reshaping NLPand other fields through a range of advancements. Introduced by Google in a 2017 paper, transformers are specifically designed to process sequential data, such as text, by effectively capturing relationships and dependencies between elements in the sequence, r...
While powerful, the neural network methods exhibit a rather strong barrier of entry, for various reasons. In this book, I attempt to provide NLP practitioners as well as newcomers with the basic background, jargon, tools, and methodologies that will allow them to understand the principles behind...
Bad: The number of parameters in the models scales with n-gram size. There is a limit on the longest dependencies that an be captured. 3.Recurrent Neural Network LM That is to say, using arecurrent neural networkto build our LM.
Once the network has registered the tokens in the input, that information is passed through the earlier trained hidden layers. The nodes it passes from one layer to the next analyze larger and larger sections of the input. This way, an NLP network can eventually interpret a wholesentenceorpara...

neural network(神经网络): an introduction(一) 当下深度学习技术已经运用到很多领域和任务中,笔者也是一个初学者,主要研究方向是自然语言处理,接触时间大概一年左右,也不算深入,在这里写下一些读书笔记吧,和大家一起学习。鉴于笔者水平有限,难免有些不正确的地方,还望看到的朋友不吝赐教。
Concepts in Neural Networks for NLP byGraham Neubig,Pengfei Liu, and other contributors This is a repository that makes an attempt to empirically take stock of themost important concepts necessary to understand cutting-edge research in neural network models for NLP. You can look at two figures be...
