Predict responses using a trained recurrent neural network and update the network state

You can make predictions using a trained deep learning network on either a CPU
or GPU. Using a GPU requires
Parallel
Computing Toolbox™ and a CUDA^{®} enabled NVIDIA^{®} GPU with compute capability 3.0 or higher. Specify the hardware requirements using the 'ExecutionEnvironment' name-value pair argument.

`[updatedNet,YPred] = predictAndUpdateState(recNet,sequences)`

`[updatedNet,YPred] = predictAndUpdateState(___,Name,Value)`

`[`

predicts responses for data in `updatedNet`

,`YPred`

] = predictAndUpdateState(`recNet`

,`sequences`

)`sequences`

using the trained
recurrent neural network `recNet`

and updates the network
state.

This function supports recurrent neural networks only. The input
`recNet`

must have at least one recurrent layer.

`[`

uses any of the arguments in the previous syntaxes and additional options specified
by one or more `updatedNet`

,`YPred`

] = predictAndUpdateState(___,`Name,Value`

)`Name,Value`

pair arguments. For example,
`'MiniBatchSize',27`

makes predictions using mini-batches of
size 27.

When making predictions with sequences of different lengths, the mini-batch size can impact the amount of padding added to the input data which can result in different predicted values. Try using different values to see which works best with your network. To specify mini-batch size and padding options, use the `'MiniBatchSize'`

and `'SequenceLength'`

options.

All functions for deep learning training,
prediction, and validation in Deep Learning
Toolbox™ perform computations using single-precision, floating-point arithmetic. Functions
for deep learning include `trainNetwork`

, `predict`

, `classify`

, and
`activations`

. The
software uses single-precision arithmetic when you train networks using both CPUs and
GPUs.
