1. Recurrent neural Network (RNN) Although the expansion from the multilayer perceptron (MLP) to the cyclic Neural network (RNN) seems trivial, it has far-reaching implications for sequence learning. The use of cyclic neural networks (RNN) is used

As an example of the open dataset of the SRL task in CoNLL-2004 and CoNLL-2005 Shared tasks, we practice the following tasks: Given a sentence and a predicate in this sentence, the predicate corresponding argument is found in the sentence by the way of sequence annotation, Annotate their semantic roles at the same time.

containing monthly data for the first five months, data for the first five weeks, and data for the first five days). But the solution is limited: What if last year's detailed data is really important? What if there is a clear event that must be taken into account (e.g. election results) the year before last?In addition to the long training time, RNN faced another problem is the long-running, early memory forgotten. In fact, as the data passes through the RNN, some information is lost at each mo

"This is an analysis of the changed network model, the other writing is not comprehensive" 1, "deep learning approach for sentiment analyses of short texts" Learning long-term dependencies with gradient descent are difcult in neural network language model because of the vanishing Gradients problem The long-term dependence of learning gradient descent is difficult in the neural network language model, because the gradient vanishing problem In we experiments, convlstm exploit
with long-term dependency problems, but in the actual process, RNN does not perform well. But GRU and LSTM can deal with gradient dissipation problems and long-term dependencies. 5. Gated Circulation Unit (Gated recurrent unit,gru) and Long short Memory network The difference between the base Rnn,gru and LSTM is the network structure of the loop body A. GRU and LSTM
input and output are variable, the rnn-recurrent neural network is easier to solve. For a rnn, each cell is usually used with lstm. There is also GRU substitution, GRU accuracy may not be as lstm, but more convenient to calculate, because he is the simplification of lstm. The model of this paper is similar to the model of Encoder-decoder, the parts of enc
information from the past. If the weights change to 0 or 100, the previous State does not matter. In general, rnn can be used in many fields. Although most of the data does not have time series, such as audio and video, they may be represented as sequences. The image and text sequence can be input in the form of one pixel or character each time. In this way, the time-related weights are not from the status that appeared in the previous x seconds, but represent the previous status of the sequenc

differentiate between the output and the state of the RNN . What's the use of doing this? Look first. First look at one of the most basic examples, consider the Vanilla Rnn/gru Cell (Vanillarnn is the most common RNN, corresponding to the TensorFlow), the working process is as follows: At this point, s_t = y_t = h_t, the distinction between these two really useless. But. What if it's LSTM. For LSTM, its

structure is very critical, but also the premise of the next step of semantic analysis. 2. The extent to which syntactic analysis is helpful for these two tasks (original question). The original problem is very good, can expand a lot of thinking. Before the advent of the alchemy, perhaps we could give a very optimistic answer, such as 60%. But now, we need to be thoughtful. The main reason is that the powerful time series model (sequential modeling) such as rnn/
Language modelThe so-called language model refers to the probability of a word appearing in the next position when a number of previous words are learned.The simplest approach is to n-gram the language model, where the current position is related only to the words in the previous n positions. So, the problem is that n is small and the language model is not expressive enough. N is large, it is not possible to characterize the context effectively when it encounters sparsity problems.The
