We can easily create Stacked LSTM models in Keras Python deep learning library. The set of images in the MNIST database was created in 1998 as a combination of two of NIST's databases: Special Database 1 and Special Database 3. Encoder-Decoder automatically consists of the following two structures: An autoencoder is a type of artificial neural network used to learn efficient codings of unlabeled data (unsupervised learning). If a multilayer perceptron has a linear activation function in all neurons, that is, a linear function that maps the weighted inputs to the output of each neuron, then linear algebra shows that any number of layers can be reduced to a two-layer input-output model. In the case of image data, the autoencoder will first encode the image into a lower-dimensional representation, then decodes that representation back to the image. This part covers the multilayer perceptron, backpropagation, and deep learning libraries, with focus on Keras.

While TensorFlow is an infrastructure layer for differentiable programming, dealing with tensors, variables, and gradients, Keras is a user interface for deep learning, dealing with layers, models, optimizers, loss functions, metrics, and more.. Keras serves as the high-level API for TensorFlow: Keras is what makes TensorFlow simple and productive. First, you must transform the list of input sequences into the form [samples, time steps, features] expected by an LSTM network.. Next, you need to rescale the integers to the range 0-to-1 to make the patterns easier to learn by the LSTM network using About the dataset.
