The original LSTM model has only one single hidden LSTM layer, but as you know, in cases of simple Feedforward Neural Networks, we usually stack layers to create hierarchical feature representation of the input data. So does this also apply to LSTMs? What if we want to have an RNN with stacked LSTM. For example, a two layer LSTM.

Hierarchical Multiscale LSTM (Chung et al., 2016a) is a state-of-the-art language model that learns interpretable structure from character-level input. Such models can provide fertile ground for (cognitive) computational linguistics studies. This is an example of using Hierarchical RNN (HRNN) to classify MNIST digits. HRNNs can learn across multiple levels of temporal hiearchy over a complex sequence. Usually, the first recurrent layer of an HRNN encodes a sentence (e.g. of word vectors) into a sentence vector. Hidden states of LSTM are used to calculate the correlation score of event pair to infer subsequent events. Hu et al. [20] built an event sequence prediction model based on a hierarchical LSTM ...

Proposed Architecture 3.1. Hierarchical Cascaded Mapping Instead of utilizing a vanilla LSTM-RNN mapping from text derived input features to acoustic output features, for the purpose of unit selection we propose a hierarchical cascaded mapping graph. Long short-term memory is an artificial recurrent neural network architecture used in the field of deep learning. Unlike standard feedforward neural networks, LSTM has feedback connections. It can not only process single data points, but also entire sequences of data. For example, LSTM is applicable to tasks such as unsegmented, connected handwriting recognition, speech recognition and anomaly detection in network traffic or IDSs. A common LSTM unit is composed of a cell, an input gate, an outpu Stacked LSTM is a special version of hierachical recurrent neural networks, where hard-wired memory and gating units help long-term preservation of state information. Hierarchy and recurrence have been explored in many works. LSTM Language Model We learn a language model using LSTMs. Learns to predict the next word given previous words in the sequence.

The first LSTM layer processes a single sentence and then after processing all the sentences, the representation of sentences by the first LSTM layer is fed to the second LSTM layer. To implement this architecture, you need to wrap the first LSTM layer inside a TimeDistributed layer to allow it to process each sentence individually.
