Let us take for example these two sentences : “On Monday, it was snowing” and “It was snowing on Monday”. RNNs have demonstrated great suc-cess in sequence labeling and prediction tasks such as handwrit-ing recognition and language modeling. Time series prediction problems are a difficult type of predictive modeling problem. in 2015 . This is because of their property of selectively remembering patterns for long durations of time. So, lets start with RNN. On the other hand, convolutional neural networks have a finite receptive field [11].

There's also this paper Noisin: ... LSTM language model not working. Such networks can be roughly structured as architectures containing the input embedding level for continuous representation of words in the vector space, recurrent cells and the output layer for prediction of the next word in a sequence. The classical example of a sequence model is the Hidden Markov Model for part-of-speech tagging. Talking about RNN, it is a network that works on the present input by taking into consideration the previous output (feedback) and storing in its memory for a short period of time (short-term memory).
